Window Styles and Design Options

Start with how you want your home to look, feel, and function. As a local dealer, we carry multiple lines, including Sunrise and Polaris, to fit your style, budget, and performance goals. Want to see and operate the options in person? Stop by our Shrewsbury showroom or call 314-353-8350 for a quick, no-pressure design chat. You can also browse our Windows & Doors overview.

Core styles at a glance

• Double-Hung: Classic look with two operable sashes that tilt in for easy cleaning. Great ventilation for bedrooms, living rooms, and traditional facades.
• Slider: Smooth, side-to-side operation for wider openings and tight exterior spaces near decks, patios, or walkways.
• Casement/Awning: Hinged, crank-out operation for excellent ventilation and a tight weather seal. Casements catch breezes; awnings shed light rain and work well over sinks or in bathrooms.
• Picture: Fixed glass that maximizes views and natural light. Often paired with operable flankers for ventilation.
• Bay & Bow: Multi-panel units that project outward to add dimension, seating, and curb appeal. Combine fixed and operable panels to suit the room.
• Hopper/Basement: Compact, hinged designs that provide controlled airflow and privacy for basements, utility rooms, or small baths. See basement window options.
• Specialty Shapes/Custom: Arches, round-tops, triangles, trapezoids, and more to match architectural details or add drama in gables, stairwells, and transoms.

Not sure which style is right for each room? We’ll recommend 2–3 smart options and price them side-by-side during your free estimate.

Custom sizes for older homes

St. Louis has many older homes and unique openings. Most replacement windows are made to order, and we often tailor sizing to fit non-standard frames and preserve original trim. See Custom-Size Replacement Windows for Older Homes: What to Expect. We handle the measurements for you—book a free, no-obligation visit and we’ll make sure the fit is right the first time.

Frame materials for Missouri’s climate

• Vinyl: Low maintenance and strong value with excellent thermal performance, reliable through humid summers and freeze–thaw cycles.
• Composite: Stable, durable frames with slimmer profiles and solid energy performance; usually mid-to-premium price points.
• Fiberglass: Rigid and dimensionally stable for larger openings and sharp temperature swings; resists warping and expands/contracts less.
• Wood-clad: Classic wood interior with a protected exterior; ideal for historic looks. Some upkeep over time. More: Are Wood-Clad Windows Worth It for Replacement Projects?

Prefer to compare materials in person? We’ll bring samples to your home or show you in the showroom and quote multiple options so you can pick the best value.

Design options to match your home

• Interior/exterior colors: From classic whites to modern darks and two-tone combinations. Explore our Color System.
• Glass and grids: Privacy/obscure textures, decorative patterns, and grille styles (between-the-glass or simulated divided lites). See Decorative Window Options, Glass Examples, and Replacement Window Glass Options Explained for Homeowners.
• Hardware finishes: Coordinate locks and levers with your interior metals. View Finishes.

Next, see how the right glass and construction improve comfort, reduce drafts, and help lower energy costs.

Energy Efficiency That Makes a Real Difference

St. Louis has hot summers, cold snaps in winter, and plenty of humidity, so the glass and frame matter as much as the brand. We help you choose proven features that fit your home, orientation, and budget. Want tailored recommendations for each room? Call 314-353-8350 or request a quick, no‑pressure Free Quote.

Low-E coatings

Low-E glass reflects heat to where you want it (inside in winter, outside in summer) and blocks much of the UV that fades floors and furniture. It’s a comfort upgrade you’ll notice. Learn more: What is Low‑E glass and why is it important? and How New Windows Help Protect Floors and Furniture From UV Damage. Not sure which Low‑E is right for your sunniest rooms? We’ll show you options side‑by‑side in our Watson Rd. showroom or during your in‑home estimate.

Gas fills and glazing

Argon is the smart value for most double-pane windows here. Krypton is denser and best in tighter cavities, often in triple-pane units or specialty sizes, when you want top thermal performance. See Argon vs. Krypton Gas in Windows and Double-Pane vs. Triple-Pane Windows. We’ll price out argon vs. krypton (and double‑ vs. triple‑pane) so you can see the comfort and savings trade‑offs—not just hear a sales pitch.

Warm-edge spacers and insulated frames

The spacer between panes affects the temperature at the glass edge. Warm-edge spacers (stainless or foam vs. old-style aluminum) help cut condensation and energy loss at the perimeter. Pair with multi-chambered or foam-enhanced frames and proper thermal breaks to reduce drafts, improve durability, and keep interior surfaces closer to room temperature during cold snaps. Ask us to demonstrate the spacer difference on sample units—we’ll help you choose the right combo for Missouri winters and summer humidity.

How to read the NFRC label (and what it means here)

• U-factor: Heat loss. Lower is better for year-round comfort and winter efficiency in Missouri.
• SHGC (Solar Heat Gain Coefficient): Sun heat passing through. For south- and west-facing windows with strong afternoon sun, aim lower to curb summer heat; on shaded or north-facing windows, a moderate SHGC can allow helpful winter gain.
• VT (Visible Transmittance): Daylight. Higher means more natural light; balance VT with SHGC and privacy goals.

ENERGY STAR helps you spot efficient combinations that meet our region’s criteria. Details: What is the National Fenestration Rating Council (NFRC) rating? and Are replacement windows Energy Star approved? During your estimate, we’ll review actual NFRC labels for your shortlisted products and recommend room‑by‑room glass packages based on your home’s orientation.

Comfort, noise, and bill savings: set realistic expectations

Expect better comfort (fewer drafts and hot/cold spots) and a lower heating/cooling load. Savings depend on your home, current window condition, and glass package. Efficient windows can also reduce outside noise, especially with thicker glass, wider airspaces, or laminated panes, but they won’t soundproof a home. Learn more: Do Replacement Windows Reduce Outside Noise?, How much can I save with energy‑efficient windows?, and Will energy‑efficient windows lower my energy bills? We’ll set clear expectations up front—no pressure, no gimmicks—so you know what comfort gains and savings make sense for your home.

Next, here’s how we install your windows the right way, which method we recommend, and what to expect step by step.

How We Install: Pocket vs. Full-Frame and What to Expect

Every home is different, so we match the installation method and workflow to your house. During your no‑pressure visit, we’ll walk you through options, show photos, and, when it makes sense, price both methods so you can choose what fits best.

Which installation method we recommend

• Insert (pocket) installation: We set a new custom-sized window into your existing frame and interior trim. Best when your current frame is square and sound and you want minimal disruption. It’s faster, cost-efficient, and preserves details you like. During your free estimate, we’ll confirm if your frames qualify and explain how this approach saves time and mess. More: Full-Frame vs. Insert Replacement Windows.
• Full-frame installation: We remove the entire existing window, frame, and trim as needed, then rebuild the opening with new flashing, insulation, and trim. Ideal when frames are rotted, out of square, or you want to change size or style, or maximize glass. We’ll show before/after examples and review trim options so you know exactly what the finished result will look like. Guide: Full-Frame vs. Insert Replacement Windows.

Not sure which route is right? We’ll recommend what’s best for your home and budget—not what’s easiest for us. Ready to talk it through? Call 314‑353‑8350 or request a free quote.

Interior vs. exterior access and site protection

Most replacements are installed mainly from the inside for better weather control and protection, though we may need outside access for sealing and trim. How we keep your space clean and safe:

• Protect: Floor runners, drop cloths, and shoe covers from entry to work areas
• Contain dust: Careful removal, HEPA-vac cleanup, and wipe-downs as we go
• Weather/finish protection: We stage one opening at a time to limit exposure
• Seal and flash: Proper pan/head flashing, shims, low-expansion foam, and sealants to manage water and air. Details: How Window Installers Prevent Leaks and Water Intrusion

Have allergy concerns, pets, or rooms you’d like us to start with? Tell us when you schedule and we’ll plan around your day. Learn where we work from and why: Do replacement windows get installed from the inside or outside? Concerned about interior trim or drywall? Read Will Window Replacement Damage Interior Trim or Drywall?

Lead-safe handling for pre-1978 homes

If your home was built before 1978, we follow EPA Renovation, Repair and Painting (RRP) lead-safe practices, including containment, careful removal, and thorough cleanup. Mention your home’s age when you book so we arrive prepared. Details: Lead‑paint regulations for homes built before 1978.

Brick, stone, and stucco openings

St. Louis has many masonry and stucco homes. These openings often favor insert installs to avoid disturbing the facade, but full-frame can be done with the right plan, flashing, and patching. Some projects need specialized tools, trim details, or minor exterior repairs. Bring photos to your estimate—or we’ll take them on site—so we can recommend the cleanest, most cost‑effective approach. More: Do contractors need to remove brick or stone to replace a window? and Why stucco or masonry windows need special treatment.

Homeowner prep and day-of checklist

• Clear 3–4 feet around each window (inside and, if practical, outside)
• Remove blinds, curtains, and window hardware unless we’ve arranged otherwise
• Take down wall decor near work areas; cover delicate items
• Disarm window sensors/alarms and secure pets
• Reserve a nearby parking spot and identify the best entry path

Prefer we handle blinds or basic furniture moves? Ask about add‑on assistance when you schedule—our goal is to make install day easy. Details and optional services: Do I need to prepare my home before installation? and Will installers need to remove furniture, blinds and curtains?

Timelines: from contract to install, and the day-of

Lead times depend on brand, season, and scope. After final measurements, we place your custom order and schedule installation when your windows arrive. Many projects finish in a day; larger homes may take longer. If you’re coordinating a remodel or have a deadline (listing your home, new baby, etc.), let us know and we’ll do our best to accommodate.

Transparent Pricing, Specials, and Financing

No surprises—just clear numbers and what they include. Your window replacement price comes from:

• Size and count: More or larger units cost more; custom shapes or sizes can add lead time and price. We’ll measure precisely and show how each opening impacts the total.
• Style and material: Double-hung vs. casement vs. slider; vinyl, composite, or wood-clad have different costs and maintenance needs. We’ll lay out side‑by‑side options so you can choose what fits your budget and priorities.
• Glass package: Low‑E coatings, argon or krypton gas, laminated or tempered safety glass, and sound‑control options affect price and performance. We’ll explain what’s worth it for your home—not just what’s “premium.”
• Installation method: Insert/pocket installs are typically faster and lower cost. Full‑frame replacements address framing, flashing, and insulation and can add scope. We’ll recommend the right approach for each opening.
• Trim and exterior work: Interior trim changes, exterior capping, brickmould/sill rebuilds, and any masonry or siding interface work are priced per opening—and itemized on your quote.

Our workmanship warranty (plain‑English summary)

Window Replacement FAQs for St. Louis Homeowners

Have questions? Here are straight answers and quick links to our in-depth guides, written for St. Louis homeowners. If you want answers tailored to your home and budget, schedule a quick, no-pressure visit and we’ll map out options, timing, and pricing.

Timing and logistics

• What is the typical turnaround time from contract to installation? Lead times vary by season, brand, glass package, and whether permits are needed. We’ll give you a clear timeline after final measurements. Read more: here.
• How long will it take to install my replacement windows? Many projects finish in a day; larger homes or full-frame work can take longer. We complete one opening at a time and clean as we go. Read more: here.
• Do replacement windows get installed from the inside or outside? Often from the inside for protection and access, though trim/siding details or full-frame installs may require exterior work. Read more: here.

Tip: Want a project-specific schedule? Book your free in‑home measure and we’ll lock in a clear timeline.

Seasonality

• When is the best time of year to replace windows in St. Louis? We install year-round; spring and fall are popular, but summer and winter work well with the right plan and materials. Read more: here.
• Can I replace my windows in winter without losing heat? Yes. We swap one window at a time, isolate rooms, and minimize heat loss with quick, efficient steps. Read more: here.

Planning around a move, renovation, or energy-bill cycle? Tell us and we’ll schedule accordingly.

Codes and safety

• What is tempered glass and when is it required? Tempered safety glass is stronger and designed to crumble rather than shard. Codes require it in “hazard” locations. Read more: here.
• When do building codes require tempered windows? Common areas include near doors, bathrooms, stairways, and low sills. Your project manager will verify locations. Read more: here.
• Do window companies follow lead-paint regulations for homes built before 1978? Yes. Lead-safe work practices (EPA RRP) with proper containment, HEPA cleanup, and documentation are required and followed. Read more: here.

We handle permits, code checks, and EPA RRP compliance—so you don’t have to.

Energy efficiency

• Are replacement windows ENERGY STAR approved? We offer ENERGY STAR-rated options. Qualification depends on the exact glass and frame package you choose. Read more: here.
• What is the National Fenestration Rating Council (NFRC) rating? It’s the independent label that lets you compare U-Factor, SHGC, Visible Transmittance, and Air Leakage across brands. Read more: here.
• What is Low‑E glass and why is it important? Low-E coatings reflect heat and block UV to keep St. Louis homes comfortable year-round and protect interiors. Read more: here.

Tell us your comfort goals and budget—we’ll recommend the right glass package and ratings for Missouri’s climate.

Costs and promotions

• How much does window replacement cost in St. Louis? Price depends on size, style, material, glass, and installation method (insert vs. full-frame). We provide written, no-pressure quotes. Read more: here.
• Are discounts or promotions available for window replacement? Yes. Seasonal offers come and go; we keep terms simple and transparent. Read more: here.
• Are financing options available for window installations in St. Louis? Yes—ask about current plans and approvals. Read more: here.

Get ballpark pricing fast over the phone, or exact numbers after a free measurement.

Materials and fit

• Which window material is best for Missouri’s climate? Vinyl offers value and low maintenance; fiberglass adds strength; wood-clad delivers warmth. Your goals and budget decide. Read more: here.
• Can my existing windows be repaired instead of replaced? Sometimes a balance, hardware, or glass-only fix is smart. If frames are rotted or inefficient, replacement is better. Read more: here. See also: What Are Sash Replacement Kits and When Should You Use Them?
• Can I purchase windows and install them myself? You can, but precise measuring, flashing, and sealing are critical. DIY mistakes risk leaks and voided warranties. Read more: here.
• Will window replacement damage interior trim or drywall? Generally, no—proper protection and technique minimize risk. Read more: here.

Not sure which way to go? Stop by the showroom to compare frame samples and glass options.

Openings and structure

• Can you make a window bigger during replacement? Often yes, with proper framing, headers, and permits. It adds time and cost. Read more: here.
• Can you add a new window to an existing wall? Yes. Expect framing, flashing, insulation, and sometimes engineering. Read more: here.
• What is the maximum window size that can be installed? It depends on the product, wind load, glass package, and code limits (like egress). Read more: here.
• See also: When you need structural planning before adding or enlarging windows

We’ll confirm feasibility and any permits during your on-site assessment.

Care and ownership

• What products should I use to clean my new windows? Use mild soap and water with a soft cloth; avoid abrasives and harsh chemicals on Low‑E glass and finishes. Read more: here.
• What happens to my old windows after replacement? We remove them and handle disposal. Where possible, components are recycled; ask if you want to keep anything. Read more: here.

On installation day, we’ll show you how to operate and care for your new windows.

For 28+ years, our family has helped St. Louis homeowners choose windows that fit both their homes and their budgets—without the hard sell.

How it works

• Start with a quick call or form: Call 314-353-8350 or send the short form at viviano-inc.com/free-quote/. Share your name, phone or email, ZIP code, and a few notes about your goals, style, or budget. Have photos or rough sizes? Include them—optional but helpful.
• Consult your way: Choose an in‑home visit for measurements and guidance, or stop by our showroom at 7530 Watson Rd, Shrewsbury, MO 63119 (Mon–Fri, 8:00 a.m.–4:00 p.m.; closed Sat–Sun). You’ll talk with a knowledgeable, non‑commissioned team member.
• Get a clear, written estimate: We’ll provide a straightforward quote that spells out brand/model, glass and efficiency options, installation method (insert/pocket or full‑frame), color/finish choices, lead times, and warranty info—so you can compare apples to apples.
• Take your time: Review at your pace. We’re here to answer questions, not to pressure. Quotes are typically valid for 30 days; ask us to confirm the current period. For complete details on any current specials, please call.
