Why Homeowners Choose Viviano Window & Door

For 28+ years, our family has helped St. Louis homeowners get reliable, energy‑efficient windows—without the hard sell. Comparing quotes or just getting started? Visit our showroom at 7530 Watson Rd, Shrewsbury, MO 63119 (Mon–Fri, 8:00 a.m.–4:00 p.m.) or call 314‑353‑8350 to talk through your project with a local, non‑commissioned team member.

We’re a dealer, not tied to a single brand. Because we carry proven manufacturers like Sunrise and Polaris, we can recommend what truly fits your budget, style, and performance goals. Expect clear options, side‑by‑side pricing, and honest pros and cons—so you can decide at your pace.

Your installation is handled by trained and insured installers who follow manufacturer specifications and local codes. For homes built before 1978, we use EPA Lead‑Safe practices. We protect your home, install correctly, seal for performance, and clean up well—so the only thing you notice is the comfort and curb appeal. Curious about our methods? See how we prevent leaks and water intrusion.

We keep overhead low by limiting TV, radio, and billboards, so more of your money goes into better windows and expert installation. Ask for good/better/best pricing to see where the value lands for you.

What We Install

From classics to custom shapes, we install the styles homeowners ask for most—sized to your openings, matched to your home’s design, and installed with care by a local, family‑owned team. Not sure what’s best for your space or budget? Let’s talk during a free in‑home estimate.

• Double‑Hung: Two movable sashes for top/bottom ventilation; tilt‑in sashes simplify cleaning.
• Casement: Side‑hinged, crank‑out operation with a tight seal when closed; great airflow and efficiency.
• Slider: Horizontal gliding that saves space; ideal near patios, decks, and walkways.
• Picture: Fixed glass for wide views and maximum light; often paired with operable flankers.
• Bay & Bow: Multi‑panel projections that bring in light from several angles and boost curb appeal.
• Awning: Top‑hinged to vent during light rain; good higher on walls or over sinks.
• Specialty Shapes: Round‑tops, arches, circles, trapezoids, and more—matched to your home.

Every window we supply is made‑to‑order for a precise fit—even custom sizes for older St. Louis homes with non‑standard or masonry openings. Tailor the look with interior/exterior colors, grille patterns, and glass options like Low‑E packages tuned for Missouri’s climate, argon/krypton gas fills, privacy glass, and tempered safety glass where codes require it.

How Our Installation Process Works

1. No‑pressure consultation
   We start by listening to your goals (comfort, curb appeal, noise), budget, and timeline. We review styles and options across several brands and provide a written estimate without gimmicks. See what the visit includes: What happens during a free window estimate?

2. Professional measurements
   A trained technician verifies each opening, notes wall conditions, and checks code‑related needs (for example, tempered glass near doors). Measurements are precise for a custom build that minimizes gaps and callbacks. Why accuracy matters • What if the wrong size is ordered?

3. Order and scheduling
   We place your custom order and share realistic manufacturing and delivery timelines. Need HOA approvals or permits? We can help coordinate. Learn more: HOA approvals and permits.

4. Installation day
   We protect work areas, replace openings one at a time, and install from the inside or outside as appropriate. For pre‑1978 homes, we follow EPA lead‑safe procedures. Learn more: Inside or outside install?



5. Seal, insulate, finish, and clean up
   We set, square, and secure each unit; insulate with low‑expansion foam; add flashing/trim as needed; and seal with the right caulk for your materials. We reinstall or replace interior/exterior trim per scope, clean up thoroughly, and demonstrate operation and care. Concerned about finishes? See trim and drywall considerations.

Built for Missouri’s Climate: Energy Efficiency

Missouri swings from humid summers to icy snaps. The right glass package matters as much as the frame. We’ll help you choose features that keep rooms comfortable year‑round—without overspending.

Low‑E glass coatings
Invisible layers reflect heat back to its source, helping your home stay cooler in July and warmer in January, while cutting UV that can fade floors and furnishings. How Low‑E works • Protect floors and furniture from UV.

Insulating gas fills
Argon is the common, cost‑effective pick for double‑pane units; krypton performs better in thinner spaces, often in triple‑pane. Argon vs. krypton.

Double‑pane vs. triple‑pane
Double‑pane Low‑E with argon suits many homes. Triple‑pane can add winter comfort and noise reduction but with added weight and cost. Compare panes.

How to compare performance
Use the NFRC label: U‑Factor (lower is better), SHGC, Visible Transmittance, and Condensation Resistance. ENERGY STAR certification is a quick sign the window meets regional efficiency targets. ENERGY STAR info • What makes windows efficient?

Brands and Design Options

We source multiple window lines, including trusted names like Sunrise and Polaris, so we can recommend the best fit for your goals. During your consultation, we compare performance (U‑Factor, SHGC, air leakage), style and sightlines, materials, hardware, warranty terms, lead times, and total budget.

Dial in the details: interior/exterior finishes, decorative or privacy glass, grids/mullions, and hardware. Bring photos or HOA guidelines to our Shrewsbury showroom, or we’ll come to you—no pressure, just options that fit your budget.

Pricing, Quotes, and Financing (No Gimmicks)

After a quick conversation and a site visit or showroom consult, you’ll receive a clear, written, line‑item quote with the exact products discussed, the installation method (pocket vs. full‑frame), and any options you’re considering (full‑frame vs. insert explained).

Warranties and Workmanship

Because we’re a dealer, product warranties vary by brand and model. During your free estimate, we’ll review the exact written warranty—what’s covered (frame, hardware, glass, IG seals), coverage periods, transferability, exclusions, and how to request service.

Quality installation protects your warranty and your home. Viviano arranges professional installation by trained and insured crews who follow manufacturer specifications and local best practices for sealing, flashing, and cleanup. For pre‑1978 homes, we use lead‑safe procedures. At completion, we demonstrate operation and address any punch‑list items.

Window Installation FAQs

• How long will it take to install my replacement windows? Most small projects (4–8 windows) finish in a day; larger projects take 1–3 days depending on site conditions and weather. Details
• Do replacement windows get installed from the inside or outside? Often both, with most work typically inside and exterior sealing outside as needed. What to expect
• When is the best time of year to replace windows in St. Louis? Any season works with proper prep. Spring/fall book early; winter/summer are common, too. Pros and cons
• What installation method will be used: pocket vs. full‑frame? We recommend after inspection. Pocket preserves trim when frames are sound; full‑frame is best for rot, water damage, or new trim. Compare methods
• Do companies follow lead‑paint regulations for homes built before 1978? They must. We use lead‑safe practices: containment, dust control, and thorough cleanup. Learn more
• Will installers need to remove furniture, blinds and curtains? Please clear a few feet around each opening and remove treatments ahead of install. Prep checklist
