Double Hung Window Installation

Think of a double-hung window as two moveable sashes—one on top, one on bottom—that open independently. Both sashes tilt inward, so you can clean the outside glass from the comfort of your home. If you’re comparing options for a classic look with modern efficiency, double-hungs are a smart, versatile choice. Viviano Window & Door installs and replaces double-hung windows across Greater St. Louis with a focus on energy performance and value—no obligation, no pressure, just clear options and pricing. Want to explore other styles too? See our Windows & Doors.

We’re a family-owned company of 28+ years (about us) known for no high-pressure sales and fair pricing made possible by low overhead: The Intersection of Price and Quality®. We’ll walk you through side‑by‑side choices (without pushing a single brand) so you get the right window for your home and budget.

Choose from ENERGY STAR–ready packages with Low‑E and gas fills, and made‑in‑the‑USA lines we carry, including Sunrise and Polaris. These windows are built for durability, tight weatherseals, and year‑round comfort in Missouri’s climate. We’ll explain the energy ratings and upgrades so you can decide what’s truly worth it (double‑ vs. triple‑pane explained).

Why Homeowners Choose Double‑Hung Windows

Homeowners across St. Louis pick double‑hung windows for everyday practicality and long‑term value—and because they’re easy to live with year‑round. If you’re exploring options, we can walk you through features and pricing in a quick, no‑pressure visit.

• Ventilation control: Open the top sash for safe airflow while keeping the bottom closed, helpful for homes with kids and pets. Venting warm, humid air up helps balance humidity and reduces the drafty feel on breezy days. During your consultation, we’ll show easy‑vent and child‑safety features across brands.
• Easy cleaning: Both sashes tilt in, so you can clean exterior glass from inside. No ladders needed, even upstairs. Stop by our Shrewsbury showroom (7530 Watson Rd) and we’ll demo the tilt‑in function.
• Energy performance: Continuous weatherstripping, interlocking meeting rails, and insulated glass packages (Low‑E with argon, with optional triple‑pane on select lines) work together to cut winter heat loss and summer heat gain. We’ll help you choose options that meet or exceed ENERGY STAR for our region—and give you clear, side‑by‑side pricing. Learn more about Low‑E and energy efficiency and see a quick double‑ vs. triple‑pane comparison.
• Safety: Vent locks let you leave a sash slightly open without fully unlocking the window. Many lines include multi‑point or dual locks (varies by brand and size). We’ll point out which models include these and why they matter.
• Timeless style: A classic look that fits historic brick, Craftsman, ranch, and contemporary homes, with grille patterns to match your home’s character. Bring a photo of your exterior—we’ll recommend patterns and colors that complement it.
• Low maintenance: Modern vinyl and composite frames won’t rot or peel and never need painting. UV‑stable exterior colors on select brands keep their finish with minimal upkeep. If you’re tired of scraping and painting, we’ll show finishes that hold up to Missouri sun and seasons. See our guide to low‑maintenance window materials.

Because we source from multiple manufacturers, including popular vinyl and composite lines, you get the right mix of features and price—true to our “Intersection of Price and Quality®” promise. You’ll see options, not a one‑brand pitch.

Not sure if double‑hung is the better pick than single‑hung for your project? Check the quick comparison below, then get friendly, no‑pressure advice from our team. Call 314‑353‑8350, request a free quote, or visit our showroom Mon–Fri, 8:00–4:00.

Double‑Hung vs. Single‑Hung: Which Fits Your Project?

Quick difference: a double-hung window has two operable sashes, top and bottom, that typically tilt in for cleaning. A single-hung looks similar, but only the bottom sash opens. Want to see the tilt-in feature in person? Stop by our Shrewsbury showroom (7530 Watson Rd) or ask for a quick demo during your free in-home estimate.

When a double‑hung is the better choice

• Easier upstairs cleaning: Both sashes tilt in, so you can clean exterior glass from inside.
• Flexible airflow: Open the top to vent warm air while cracking the bottom for cool air, helpful for spring and fall comfort without running HVAC as much.
• Historic styling: Double-hungs pair naturally with true or simulated divided lites to match classic St. Louis architecture while keeping modern performance.

When a single‑hung may make sense

• Budget-focused projects: Fewer moving parts can lower cost without changing the look.
• Spaces where the upper sash isn’t needed: First-floor windows you can clean from outside, or rooms that rarely need top ventilation.

Working on a basement? You may want a different style—see the best replacement options for basement windows.

Energy note: Whether single- or double-hung, performance comes from build quality and installation: tight weatherstripping, insulated glass (Low‑E, argon), and careful air sealing during install. That’s what prevents drafts and helps control utility costs, not the sash count alone. We carry multiple trusted brands so you get the right efficiency and features for your home and budget.

Once you’ve chosen the type, we’ll help you dial in size, grille pattern, colors, hardware, and glass to fit your home and budget—then show clear pricing at the intersection of price and quality. Ready to compare options? Call 314‑353‑8350 (Mon–Fri, 8–4) or request a free, no‑pressure quote and we’ll bring samples to you.

Sizes, Styles, and Custom Options

No two St. Louis homes are identical, and neither are their window openings. We measure every double‑hung to your opening, including out‑of‑square frames and non‑standard sizes common in older brick and stone homes, so your new units fit cleanly without forcing existing trim or masonry. Want a traditional “cottage” look with a taller lower sash? We can match that too. Schedule a quick, no‑pressure in‑home measure and we’ll show you what fits best before you spend a dollar. See what to expect with custom‑size replacement windows for older homes.

Make it yours with options across the brands we carry (like Sunrise and Polaris):

• Custom sizing and styles
  • Built to the fraction of an inch for tight fits
  • Equal or cottage/oriel sash splits to match original sightlines
  • Transoms and shaped units paired with double‑hungs for added light
• Colors and finishes
  • Exterior laminates and durable coatings in modern hues (black, bronze, deep greens) built to resist fading, not just white or beige
  • Interior woodgrain laminates that mimic oak, cherry, or maple, or clean painted looks to complement your trim
• Grids and muntins
  • Simulated Divided Lites for raised‑bar detail
  • Grids‑Between‑Glass for easy cleaning
  • Patterns to match your home’s era: colonial, prairie, craftsman, diamond
• Hardware and screens
  • Lock and lift finishes in brushed nickel, oil‑rubbed bronze, matte black, brass, and more
  • Screen options from standard fiberglass to better‑visibility mesh and pet‑resistant choices; half or full screens depending on the line
• Glass choices for privacy and performance
  • Obscure/privacy glass (rain, frosted, reed) for baths and sidelites
  • Tempered safety glass where code requires (near doors, floors, tubs, stairs) — see when tempered is required
  • Laminated glass to reduce outside noise and add security—see noise reduction with new windows
• Low‑maintenance materials and trim/casing options
  • Long‑lasting vinyl or fiberglass frames with tilt‑in sashes for easy cleaning
  • Interior finish work to preserve existing casing or refresh with new stool, apron, and casing profiles; exterior brickmould or flat trim to suit your facade (which window frame material lasts the longest?)

Not sure which package is right for your home and budget? We’ll lay out clear good‑better‑best paths without the sales push, so you can align looks, maintenance, and performance.

Energy Performance for Missouri’s Climate

St. Louis swings from muggy summers to chilly winters. We match your double‑hung window package to both so you stay comfortable and keep energy costs in check—without overspending.

• Low‑E glass that works year‑round: Multi‑layer Low‑E reflects summer heat outside and helps hold winter warmth in. It also cuts UV that fades floors, rugs, and furniture, reducing glare. See our guide to Low‑E glass and how new windows help protect floors and furniture from UV damage.
• Insulated glass choices: For most homes here, double‑pane glass with argon gas offers the best value. If you want maximum performance, triple‑pane or krypton‑filled options further lower heat transfer and can boost comfort in rooms with heavy sun or draft concerns. Get the details in Argon vs. Krypton and Double‑Pane vs. Triple‑Pane.
• How to read the NFRC label:
  • U‑Factor (insulation): Lower is better. In our area, many target about 0.20–0.29 for top‑tier efficiency, 0.30–0.32 for solid, budget‑savvy performance.
  • SHGC (solar heat gain): Lower numbers reduce summer heat. Sunny exposures often do well around 0.20–0.35; shaded sides can be a bit higher to balance light and winter sun.
  • VT (visible light): 0.40–0.60 keeps rooms bright without harsh glare.

  More on ratings: NFRC explained. We’ll walk you through the sticker and help you target the right numbers for each room’s sun and shade.

• ENERGY STAR options: The double‑hung lines we carry include glass packages that meet current ENERGY STAR criteria for Missouri. We’ll show the exact NFRC sticker and include it with your quote so you know exactly what you’re getting.
• Installation matters: Even the best glass will underperform if the unit isn’t air‑ and water‑sealed. Our installers use low‑expansion foam, backer rod, and high‑quality sealants, plus pan and flashing details to direct water out and away—see our article on how installers prevent leaks.

Prefer to see options in person? Stop by our Shrewsbury showroom at 7530 Watson Rd, Mon–Fri, 8–4, or call 314‑353‑8350 to compare glass packages for your home.

Our No‑Pressure Installation Process

Here’s what to expect with Viviano Window & Door for double‑hung replacement: clear steps, clean job sites, and no one‑call‑close pressure. Start with a free, no‑obligation estimate and end with windows installed the right way—on your timeline.

1. Start the conversation or visit our showroom

   Tell us what you want to improve (drafts, noise, cleaning, curb appeal). We’ll show how modern double‑hungs tilt in, seal, and lock. You’re welcome to stop by our Shrewsbury showroom to see options in person. Call 314‑353‑8350 or request a free quote, or visit us at 7530 Watson Rd, Shrewsbury, MO 63119 (Mon–Fri, 8–4).

2. In‑home evaluation and precise measurements

   An estimator visits, checks each opening, and takes exact measurements. We assess sills, frames, and finishes, note any code or safety items (including EPA lead‑safe rules for homes built before 1978), and confirm whether an insert or full‑frame approach fits each window. If HOA approvals or permits are needed, we’ll help you navigate them. See why accurate window measurements matter before you order.

3. Options and quote review without gimmicks

   We walk through glass packages, grids, colors, screens, and hardware from the brands that match your goals and budget. You’ll receive a clear, written quote with line items, installation method, and lead times—no today‑only pricing or bundles you don’t need. Ask about current specials and financing options if you’d like.

4. Custom order and scheduling

   Your windows are built to your measurements. We place the order, track manufacturing, and schedule installation when your units arrive. We’ll keep you updated with realistic timelines, and we can price/schedule your project all at once or in phases.

5. Job‑day protection

   On installation day, we protect floors and walk paths, set up containment where needed, and carefully remove blinds or curtains as discussed. Please move small items and nearby furniture when possible; we can help if needed. Expect courtesy updates and an on‑the‑way call.

6. Professional installation and air/water sealing
   

   

   We complete insert (pocket) or full‑frame replacement as planned. Openings are squared and shimmed. We insulate with low‑expansion foam or fiberglass as appropriate and seal for air and water with tapes and premium sealants per manufacturer specs and local best practices. Most work is done from the inside—see inside vs. outside installs. Winter projects are staged room by room to minimize heat loss—see winter installs.

7. Exterior finishing and interior trim

   We install or preserve interior casing as scoped. Outside, we cap or trim to match your home and seal all perimeters for a finished, weathertight result with clean, color‑matched details.

8. Clean‑up and haul‑away

   We vacuum, remove debris, and haul away your old windows. Materials are recycled when feasible. You’ll get your spaces back the same day—clean and ready to enjoy.

9. Final walkthrough and handoff

   We show how the sashes operate and tilt for cleaning, review care tips, and provide warranty information. You’ll know exactly who to call if you ever need service—no runaround.

Full‑Frame vs. Insert Installation

Choosing the right installation method comes down to the condition of your openings and the look and performance you want. Not sure which path is best for your double‑hung windows? Schedule a free, no‑pressure evaluation—we’ll check your frames and share clear, side‑by‑side pricing for both options so you can choose with confidence. Also see our guide: Full‑Frame vs. Insert.

Insert (pocket) installation

• What it is: A new window unit is placed inside your existing frame. Interior and exterior trim stay in place.
• When it’s ideal: Your current frames are square, solid, and free of rot or water damage.
• Why homeowners choose it: Faster, cleaner, and typically lower cost with minimal disruption to walls, siding, or masonry. Great for preserving original interior casing in older homes.
• What to expect: A slight reduction in visible glass because the new window sits inside the old frame. We air‑seal the cavity with low‑expansion foam and sealants to maintain performance.

Full‑frame installation

• What it is: We remove the entire existing window, including the frame, sill, and exterior casing, down to the rough opening.
• When it’s ideal: There’s rot, water intrusion, out‑of‑square frames, or you want a style change. Also best when you want full control over sightlines and glass area. Considering a larger opening? See making a window bigger during replacement.
• Why homeowners choose it: Lets us repair damage, add sill pans and flashing, insulate the rough opening, and refresh exterior and interior trim. It also gives the most flexibility to maximize visible glass.

Sightlines, energy, and cost—how they differ

• Sightlines and glass: Pocket installs usually reduce visible glass slightly (varies by brand and series). Full‑frame can reclaim or even increase visible glass and tailor trim profiles for a cleaner view.
• Energy performance: Both approaches can meet ENERGY STAR in Missouri with Low‑E and argon. Full‑frame offers the best opportunity to address air and water management at the rough opening with flashing, pans, and insulation.
• Cost and timeline: Pocket installs are generally quicker and more budget‑friendly. Full‑frame costs more due to added labor and materials, but can prevent future repairs if hidden issues exist.

What we look for during your evaluation

• Wood rot, soft sills, water staining, or failed caulking or capping
• Frame squareness (diagonal measurements), sash operation, and drafts
• Evidence of past leaks around headers or under sills
• The condition of interior casing you may want to preserve
• Pre‑1978 paint (we follow EPA Lead‑Safe practices as required)

Special considerations for brick, stone, and stucco in older St. Louis homes

• We typically do not remove brick or stone. Frames are carefully cut out, and new units are anchored to masonry with proper fasteners.
• We integrate sill pans, backer rod, and high‑performance sealants. On stucco, we score and patch for a clean, weather‑tight finish.
• Trim solutions include low‑profile brickmould, color‑matched capping, or sealant‑only finishes to respect historic aesthetics and avoid bulky add‑ons.
• For deep masonry openings or old steel casements, we may add new “buck” framing to create a square, insulated pocket before setting the window.

Compare methods: Full‑Frame vs. Insert

Pricing and How We Keep It Fair

We price double‑hung window installations the way we operate: straightforward and value‑first. Your quote reflects your home and choices, not a generic package. Tell us what matters most—budget, efficiency, or aesthetics—and we’ll tailor options so you only pay for what you want. For general guidance, see window replacement cost in St. Louis.

What affects price

• Size and count of windows (we measure precisely for an accurate, right‑sized order)
• Frame material (vinyl, fiberglass, wood‑clad) and series
• Glass package (double vs. triple pane, Low‑E type, argon or krypton gas, laminated or tempered where required)
• Colors, exterior finishes, and interior woodgrains
• Grids or muntins and hardware upgrades
• Installation method: insert (pocket) vs. full‑frame with new insulation or trim (we’ll price both and explain pros/cons)
• Prep or repair work (rot repair, sill or brickmould replacement, lead‑safe setup and disposal for pre‑1978 homes)
• Access and complexity (upper stories, stucco or brick openings, landscaping, interior trim to preserve)

Why our pricing stays competitive

• Lower overhead: as a family‑owned dealer, we keep advertising light, so more of your budget goes into the window you buy.
• No commissioned‑style selling: no one‑call‑close tactics, just product guidance and a clear, written number.
• Multiple brands and series: we recommend what fits your needs, not a single manufacturer—so you can compare performance and price.
• Transparent line items: easy, apples‑to‑apples details that help you compare any competing quote.

Options to fit your budget

• Phase your project by room or elevation, or do a whole‑home replacement for the best unit pricing and immediate efficiency gains.
• Ask about current specials and available financing.
• Prefer choices? We can show side‑by‑side “good / better / best” packages so you can pick the value sweet spot.

Codes, Safety, and Weather Readiness

From the first measure to final inspection, your new double‑hung windows are planned and installed to meet code and protect your home—no high‑pressure sales, just clear guidance and careful work.

Lead‑safe work for pre‑1978 homes (EPA RRP)

If your home was built before 1978, we follow EPA Renovation, Repair and Painting (RRP) rules. That includes lead‑safe certified crews, proper containment with plastic barriers, PPE, HEPA dust collection, careful waste handling, and cleaning verification before we leave. Read more: lead paint and window replacement.

Safety glazing and egress, handled before you order

We flag locations that require tempered or laminated glass, such as glazing within 24 inches of a door, near floors, or within 60 inches of a tub or shower—see tempered glass requirements. For bedrooms, we check egress: minimum clear‑opening size and maximum sill height. If an opening won’t meet code with a simple swap, we’ll discuss solutions before anything is ordered.

Permits and HOA coordination

Like‑for‑like replacements often don’t need a permit. Structural changes, enlargements, or egress updates usually do. We help you navigate your municipality’s requirements and can supply drawings, specifications, and insurance documents. For HOAs, we provide color samples, grille layouts, and product cut sheets to streamline approvals—more here: HOA approvals and permits.

Built for St. Louis weather, installed in any season

Winter installs are sequenced room by room to limit heat loss—see winter replacement. We use temporary coverings, minimize open time, and apply low‑expansion foam, backer rod, and cold‑weather‑rated sealants. We integrate sloped sill pans, self‑adhered flashing, and head flashing or drip caps in a shingle‑style layer with your existing materials, following manufacturer instructions and industry best practices.

Ready to get started? Call 314‑353‑8350 or request your free quote.

Warranties and After‑Install Support

Your new double‑hung windows come with two layers of protection: the manufacturer’s warranty on the product and our written workmanship warranty on the installation—so you get long‑term peace of mind from a local, family‑owned team. See also: window warranties overview.

What the manufacturer covers

• Insulated glass units (seal failure or condensation between panes)
• Operating components (balances, locks, tilt latches)
• Frame and sash materials and exterior color or finish

Terms and durations differ by material and series. Some offer transferable coverage or optional glass‑breakage protection. We’ll review the exact warranty for the window you choose and provide documentation at purchase. Keep the manufacturer ID or serial sticker on the sash or inside the frame to speed up any future claims.

Our workmanship warranty

• If an issue arises related to how your window was installed, we’ll return to diagnose and correct it in accordance with our written workmanship warranty.
• You’ll receive our warranty terms in writing with your order packet.

How to request service or an adjustment

Call 314‑353‑8350 (Mon–Fri, 8:00 a.m.–4:00 p.m.) or use our Contact Us form. Helpful details: your name/address, install date and invoice (if handy), brand/series, any label info, and a brief description or photos of the issue.

Operation and care (to keep your warranty intact)

• Daily use: We’ll show you how to unlock, raise/lower, and tilt both sashes during your final walkthrough. Always re‑seat sashes fully and lock the window to ensure proper weatherseal contact.
• Cleaning glass: Use mild dish soap and water or a vinegar‑and‑water mix with a soft, lint‑free cloth. Avoid ammonia, abrasives, razor blades, and pressure washers.
• Cleaning frames and screens: Use mild soap and water only; avoid harsh solvents or petroleum‑based cleaners. Remove screens and rinse gently with a soft brush.
• Hardware and tracks: Keep tracks clear. If lubrication is needed, use a light, non‑petroleum spray sparingly and wipe excess.
• Drainage and weeps: Periodically check and clear exterior weep holes so water can exit as designed.

Brand‑specific tips: what to use to clean new windows.

Double‑Hung Window FAQs

Are double-hung windows energy-efficient and will they lower my bills?

Yes—when you choose modern double-hung units with insulated frames, Low‑E glass, and argon (or optional krypton) gas fills. During your consultation, we’ll show you each window’s NFRC ratings and which models meet or exceed ENERGY STAR for our Missouri climate, so you can compare side by side. Real‑world savings depend on your home’s age, air sealing, and HVAC, but customers typically notice fewer drafts, steadier room temps, and less HVAC run time. Start with a free estimate or see how efficient windows affect bills.

Do installers work from the inside or outside, and how long does it take?

Most replacements are installed from the inside to protect your exterior and control dust and debris. Some details, like trim or capping, are finished outside. A typical home project takes 1–2 days depending on scope, with active time per opening often 30–90 minutes. Learn more: inside vs. outside and installation timelines.

Will my interior trim or drywall be damaged during replacement?

For insert (pocket) installations, your existing interior trim usually stays in place with minimal touch‑up. Full‑frame replacements require removing old frames and trim and installing new interior casing. We’ll explain which method fits your home and quote it clearly before you sign—no surprises. See trim and drywall impacts.

Can windows be replaced in winter without losing much heat?

Yes. We work one window at a time, use interior barriers as needed, and keep your heating on. Our foams and sealants are rated for cold weather, and we schedule around extreme temperatures when advisable. Most homeowners are surprised how little the house cools during a winter install. More here: winter replacement FAQs.

What warranties come with my new windows and installation?

Coverage varies by brand and series, but many lines include strong limited lifetime warranties on frames, sash, hardware, and insulated glass seals (often transferable). Viviano also provides an installation warranty on our workmanship. We’ll review the written coverage with you in plain language so you know exactly what’s included. See warranty details.

How do I clean and maintain tilt‑in sashes?

Unlock, raise the sash a few inches, press the tilt latches, and tilt inward while supporting the sash. Clean glass and vinyl with mild soap and water and a soft cloth. Avoid abrasives, ammonia, high‑pressure washing, and petroleum solvents. Wipe tracks, check weep paths, and apply a light silicone spray to moving parts as needed. Return the sash to an upright position and make sure it re‑engages the side balances. Tips: approved cleaning products.

Should I replace all my windows at once or in phases?

Both work. Doing them all at once maximizes consistency and usually lowers the per‑window price. Phasing helps manage budgets. We’ll help you prioritize by biggest drafts, sun exposure, and rooms you use most—and build a plan that keeps styles and finishes consistent. See replace all vs. phase.

Insert vs. full‑frame—how do I know which I need?

Insert (pocket) replacement slides a new unit into your existing frame, ideal when the frame is square and solid and you like your current trim. It’s faster and cost‑effective. Full‑frame replacement removes everything to the studs, best for rot, water damage, out‑of‑square frames, style or size changes, or when you need new flashing and insulation. After an inspection, we’ll recommend the right method for each opening—and we can quote both options where it makes sense so you can compare price and scope. Read more: Full‑Frame vs. Insert guide.
