Who We Serve
We partner with commercial decision‑makers across Greater St. Louis who want long‑lasting, energy‑efficient windows—without the runaround. If you need clear communication, predictable schedules, and real value, let’s talk about your property and timeline.
- Property managers and building owners who need clear scopes, dependable timelines, and options that meet budgets without sacrificing performance. Send us your scope or bid set for an apples‑to‑apples proposal.
- Multifamily and condos (occupied units and common areas), including HOAs, senior living, and student housing. We phase work stack‑by‑stack or floor‑by‑floor, coordinate unit access, and protect interiors while upgrading windows in lobbies, corridors, stairwells, laundry rooms, and amenity spaces—keeping residents informed and disruptions low.
- Office, retail, restaurants, schools, churches, and light industrial facilities. We plan around class schedules and services, minimize downtime for storefronts and restaurants, and coordinate with facility staff to keep operations moving.
Occupied‑building specialists: coordinated scheduling, safety barriers, minimal disruption. Before we start, we complete a no‑obligation site walk to finalize scope and measurements, then deliver a phasing plan with dates, daily headcounts, and access needs. During install, we set up barricades and signage, protect floors and furnishings, control dust, and perform daily cleanups with debris hauled off site. For sensitive environments, we can work early mornings, evenings, or off‑hours to reduce noise and customer impact. You’ll receive progress updates so managers always know what’s next.

Systems We Install
From offices and retail to multifamily common areas, we install durable, energy‑conscious window systems that fit your building, budget, and schedule. Need pricing or guidance fast? Book a quick site walk and we’ll lay out clear options—no pressure.
- Commercial aluminum windows (retrofit and full‑frame): Choose insert replacements to refresh glazing with minimal disruption and preserve finishes. Use full‑frame tear‑outs when frames are failing or water intrusion is present. Thermal‑break frames with insulated, low‑E glass help cut solar gain and drafts while meeting local energy‑code targets (see double‑ vs. triple‑pane trade‑offs). Not sure which path is right? We’ll verify conditions onsite and provide a side‑by‑side, no‑obligation budget—plus phased installation plans to limit tenant downtime.
- Storefront and entry door upgrades: Ground‑floor and lobby makeovers with new aluminum storefront framing, sidelites, and transoms improve curb appeal and daylight. We install insulated glass packages, heavy‑duty weatherstripping, and commercial‑grade swing or sliding entry doors, with hardware compatibility for panic/exit and access control (by others). We coordinate with your GC and security vendor and schedule work to minimize impact on business hours.
- Security, safety, and sound control glazing: We provide tempered safety glass where code requires it, and laminated options to deter forced entry or reduce shattering. For busy corridors and street‑facing spaces, laminated acoustic interlayers and thicker insulated glass can raise STC/OITC ratings and reduce noise. Tell us your performance targets—we’ll recommend the right package and handle the code details.
- Custom sizing, shapes, and finishes: Built‑to‑order units for non‑standard openings, arches, and round‑tops help you match existing facades. Factory‑applied painted or anodized finishes, interior/exterior color pairing, simulated divided lites, and custom tints align with brand standards or historic details. Finish samples and shop drawings are available to streamline approvals—ideal for St. Louis rehabs and branding updates.
Our Tenant‑Friendly Process
A smooth commercial install starts with planning around your operations and ends with clear documentation and support. Here’s how we deliver that, especially in occupied buildings—so tenants stay happy, spaces stay safe, and your schedule stays on track:
-
Site walk and scope alignment

- Meet with your property manager/owner/GC to clarify goals (energy savings, comfort, sound control, security), budget, timelines, and access constraints (store hours, school schedules, lift access, staging, egress paths).
- Review drawings if available, discuss historic or HOA requirements, and flag permit needs.
- Identify value‑engineered options that protect performance without inflating cost.
Outcome: Clear expectations and fewer change orders from day one.
-
Field verification and phasing confirmation
- Laser‑measure every opening and verify wall conditions, substrates, and anchorage points.
- Note code‑triggered locations (safety glazing near doors, egress paths) and any repair needs to sills or surrounding materials.
- Finalize quantities and confirm phases that minimize disruption.
Outcome: Accurate ordering, cleaner installs, and phasing that keeps businesses operating. Related: Why accurate window measurements matter.
-
Submittals, shop drawings, and product selections
- Provide a submittal package with shop drawings, manufacturer cut sheets, and finish samples.
- Detail glass makeups and performance targets (low‑E packages, laminated/tempered safety glazing, IGU thickness, U‑factor, SHGC, visible light, optional STC/OITC for sound).
- Include sealants, accessories, anchorage details, and color selections for approval. COI and safety plan available on request.
Outcome: Fast approvals and confidence that what’s specified is exactly what gets installed.
-
Schedule and phasing plan
- Build a calendar with day, night, or weekend work as needed. Coordinate tenant notifications and signage.
- Sequence deliveries to reduce clutter. Plan waste handling/recycling and weather contingencies.
- Share a communication cadence for updates and access needs.
Outcome: Minimal downtime for tenants and predictable milestones for your team.
-
Installation with safety and daily turnover
- Set safety barriers and wayfinding. Protect floors and furnishings. Manage dust and debris.
- Install to industry best practices with proper shimming, flashing, backer rod, and sealants—see how pros prevent leaks and water intrusion. Secure and weather‑tight each opening before end of day.
- Perform daily cleanup and brief the PM on progress and next‑day impacts.
Outcome: Safe, orderly jobsites and weather‑tight turnovers every day—no surprises.
-
Punch, sign‑off, and handoff
- Walk the project with your team to complete punch items quickly.
- Deliver the close‑out package: owner’s manuals, care instructions, product and labor warranties, and service contact info.
- Provide disposal/recycling documentation and maintenance plans if requested.
Outcome: Clean close‑out, clear documentation, and a single point of contact for support.

Performance and Technical Options
Make confident, cost‑smart choices that balance energy performance, comfort, and durability—without overspending. Because we source across multiple commercial manufacturers, we’ll design a window package that fits your building, budget, and schedule with no‑pressure, manufacturer‑agnostic guidance.

- Insulated glass units (IGUs) and Low‑E choices
- Double‑pane vs. triple‑pane: double‑pane IGUs are standard for most St. Louis commercial retrofits; triple‑pane is available for high‑noise corridors or specialty energy goals.
- Soft‑coat Low‑E options lower U‑factor and cut solar heat gain. We tune coatings to facade orientation to reduce hot/cold spots and HVAC load—ask for a side‑by‑side U‑factor/SHGC/VT comparison for each elevation.
- Argon‑filled IGUs are recommended in most assemblies for better thermal resistance. Warm‑edge spacers reduce edge‑of‑glass condensation.
- Thermally broken aluminum frames
- Modern aluminum systems with polyamide thermal breaks minimize heat transfer and condensation risk while maintaining strength and slim sightlines.
- Pair thermal frames with properly shimmed and sealed anchors to help prevent cold bridging at rough openings.
- Safety, security, and sound control
- Laminated glass enhances security and provides meaningful sound reduction (higher STC/OITC), ideal for street‑level retail, schools, and multifamily applications—see how windows reduce outside noise.
- Tempered glass is used where life safety requires it, such as doors, sidelites near doors, low sills, and wet areas. We clearly document all safety glazing locations in submittals.
- Glare, privacy, and UV protection
- Tinted and reflective glasses manage glare and improve comfort without overly dark interiors. In‑hand samples or a quick mockup available.
- UV‑protective glass options help protect flooring, furnishings, and merchandise from fading.
- Finishes and hardware to match your brand
- Frame finishes include clear/dark bronze anodized, factory powder coat, and PVDF (Kynar) coatings. Custom colors available.
- For operable windows, specify durable operators, limiters, and custodial locks. For storefront entries, we coordinate matching finishes and ADA‑friendly hardware.
Code, Safety, and Compliance
We treat commercial window work as a code‑driven, safety‑critical scope. Our team coordinates with your GC, facilities staff, or property manager to verify requirements, document submittals, and keep occupied spaces safe and compliant throughout the project.
- Energy code and NFRC documentation
- We select assemblies to meet IECC requirements adopted by your municipality in Greater St. Louis (City/County, St. Charles, Jefferson, and Metro East).
- NFRC‑rated products are specified where applicable. We provide NFRC certificates/labels and manufacturer cut sheets with thermal data in the submittal package.
- Safety glazing in hazardous locations
- We place tempered or laminated safety glass wherever code requires it: in and near doors, large lites near walking surfaces, along stairways/landings, and in wet areas such as shower and locker rooms.
- When security or sound control is a concern, laminated glass can meet both safety‑glazing and deterrence needs without compromising sightlines.
- Lead‑safe practices for pre‑1978 properties
- For schools, child‑occupied facilities, and any pre‑1978 buildings with lead‑based paint, we follow EPA Renovation, Repair and Painting (RRP) protocols: containment, HEPA extraction, safe removal, and cleaning verification.
- Learn more:
- Historic districts, permits, and inspections
- We coordinate with local historic review boards when projects fall within designated districts, matching sightlines, muntin profiles, colors, and reflectivity as required.
- Our office assists with permit paperwork and inspection scheduling. Submittals can include product data, shop drawings, installation details, and safety‑glazing markups for AHJ review.
- Insurance and jobsite safety
- Certificates of Insurance (general liability and workers’ compensation) are available on request, with additional insured/waiver language as specified in your contract.
- Expect clean, organized jobsites: daily housekeeping, debris removal, cordoned work areas, and end‑of‑day walk‑throughs, especially in occupied buildings.

Commercial FAQs
What are typical lead times, and how do seasonality or custom specs affect schedules?
Most standard commercial window packages install about 4–8 weeks from approved submittals, depending on manufacturer lead times and job size. Custom specs (non‑standard sizes, custom colors/finishes, laminated or tempered safety glass, acoustic or high‑performance Low‑E IGUs) can extend procurement to 8–12+ weeks. Spring and summer are peak seasons in St. Louis, which can add time. Have a fixed deadline (tenant turnover, school breaks, store reopening)? Tell us early. We can often phase work or source alternates to keep you on track. Share your target date and plans when you request a quote, and we’ll map a schedule and hold a tentative production slot.
Do you offer night or weekend work, and how do you communicate with tenants/occupants?
Yes. With advance notice, we can schedule off‑hours or weekend work to minimize disruption. For tenant‑in‑place projects, we provide a phasing plan, daily start/finish times, and unit‑by‑unit notifications. We coordinate notices (email, door hangers, lobby signage), maintain clear access paths, set dust barriers where needed, and return each opening to a secure, weather‑tight condition before we leave each day.
What are your warranty terms, service response, and do you provide emergency board‑up?
Product warranties are manufacturer‑backed and vary by system and usage. We include the applicable written manufacturer warranty with your proposal. Viviano provides a workmanship warranty on our installation; the term is stated in your contract. If a service issue comes up, we aim to assess within a few business days and will coordinate any warranty parts with the manufacturer. For unexpected glass damage, we can secure openings and provide temporary board‑up upon request (after‑hours subject to availability).
How do you handle disposal, recycling, and site cleanliness?
We remove and haul away old windows, packaging, and job debris. Where feasible, we recycle materials such as aluminum frames and glass. Crews protect work areas, contain dust, and perform daily cleanup. Openings are left weather‑tight at the end of each shift, and common areas are kept clear and safe. If you have specific sustainability or housekeeping requirements, share them with us and we’ll build them into the plan.
Can you provide insurance documentation (COI), and who handles permits/approvals?
Yes. Certificates of Insurance (with additional insured/endorsement language, if required) and W‑9s are available on request. We follow EPA lead‑safe practices on pre‑1978 properties and comply with applicable safety glazing and energy codes. For permits, we can coordinate with your GC or submit for simple window permits in many St. Louis‑area municipalities. Historic district reviews or complex scopes may require owner/architect involvement. We’ll clarify responsibilities, fees, and timelines during pre‑construction.
What payment methods and invoicing terms do you offer for commercial clients?
We accept company check, ACH, and major credit cards (a processing fee may apply to cards). Standard terms are a materials deposit at contract signing, with the balance due at milestones or completion. Net‑15/30 invoicing is available for approved accounts or through a purchase order. Your proposal will outline the schedule of values and billing cadence. If you need vendor onboarding or PO compliance, let us know and we’ll align our paperwork to your process.
