New construction projects require precise coordination between window systems and the rest of the building envelope. We measure rough openings, review shop drawings, and select window systems suited to the building's fenestration design. Proper flashing and installation sequencing matter here as much as the window product itself, since a correctly installed window performs for decades while a poorly flashed one fails early.
Full-frame replacement makes sense when frames have degraded, seals have failed, or water infiltration has damaged the surrounding wall assembly. Insert retrofit replacement, which fits a new window into the existing frame, works well when the frame itself remains sound. We plan retrofit projects to minimize disruption inside occupied buildings, often working in phases so tenants and staff can keep operating during installation.
Storefront glazing does more than let in light. It shapes how customers see your business from the sidewalk. We work with aluminum framing systems and glazing options, including tempered and laminated glass and insulated glass units, to improve visibility, safety, and thermal performance at retail entrances. Coordination with existing entrance systems keeps the finished look consistent with your building's design.
Planning a new build, retrofit, or storefront upgrade?
Some problems point to a simple repair. Others signal it’s time to replace the window system entirely. Here’s a quick way to tell the difference.
| Symptom | Likely Cause | Typical Fix |
|---|---|---|
| Drafts near the window frame | Air leakage, worn weatherstripping | Repair or full replacement, depending on frame condition |
| Fogged glass between panes | Failed insulated glass unit (IGU) seal | Glass unit replacement |
| Rising heating or cooling costs | Thermal bridging, poor insulation | Upgraded glazing or thermally broken frames |
| Water stains near the sill | Failed flashing or perimeter sealant | Flashing repair or full-frame replacement |
| Visible cracks or corrosion | Aging frames, physical damage | Replacement, evaluated case by case |
Drafty windows let conditioned air escape and let outside air in, which forces HVAC systems to work harder. Thermal bridging through aluminum frames without thermal breaks makes this worse. We can't promise a specific dollar savings, since every building's energy use depends on its own systems, but addressing air leakage is a reasonable first step toward improving occupant comfort.
Condensation on the inside surface of a window usually points to indoor humidity levels, not a product defect. Condensation trapped between the panes of an insulated glass unit is different. It signals a failed seal that has let moisture into the airspace, and that calls for glass replacement.
Cracked glazing, corroded frames, and damaged sashes affect both security and curb appeal. We evaluate each case individually. Sometimes a targeted repair solves the problem, and sometimes the frame's condition makes full replacement the more practical choice.
Extruded aluminum frames offer strength and corrosion resistance, which makes them a common choice for commercial applications. Standard aluminum conducts heat and cold efficiently, which isn't always a good thing for energy performance. Thermally broken frames interrupt that conductivity with an insulating barrier, improving comfort near the window line. Powder-coated finishes add durability against Buffalo's weather.
Fixed windows bring in daylight without opening, which suits spaces that prioritize views or natural light over ventilation. Operable windows, including awning and casement styles, allow fresh air into the space when needed. Custom-sized openings accommodate buildings with non-standard window dimensions or unique architectural features.
Insulated glass units (IGUs) trap air or gas between two or more panes to improve thermal performance, with double- and triple-glazed options available depending on the building's needs. Tempered glass adds safety in high-traffic or impact-prone areas. Laminated glass offers additional security and sound dampening. Not every opening in a building requires the same glazing specification, and we help determine which applies where.
Not sure which frame or glazing specification fits your building?
Western New York winters bring sustained cold, lake-effect snow, and repeated freeze-thaw cycles, all of which put pressure on a building’s window performance. No single product eliminates every energy concern, but the right combination of glazing, frame type, and installation quality makes a measurable difference in comfort and HVAC load.
Low-emissivity (Low-E) coatings reduce heat transfer through the glass, helping keep heat inside during winter. When comparing window systems, ask about U-factor (how well the window resists heat flow) and solar heat gain coefficient, or SHGC (how much solar heat passes through). Both are rated by the National Fenestration Rating Council (NFRC) and give you an apples-to-apples way to compare products. Argon gas fill between panes and thermal breaks in the frame further improve performance.
A high-performance window installed poorly still underperforms. Flashing, weather barriers, and perimeter sealants all need to integrate correctly with the surrounding wall assembly to prevent air infiltration and water penetration. We treat the installation assembly as part of the product, not an afterthought.
Window decisions affect more than the initial invoice. Product cost, installation quality, ongoing maintenance, and HVAC efficiency all factor into the real cost of ownership over a building's life. A slightly higher upfront investment in a better-performing system often pays off through lower maintenance needs and more consistent occupant comfort.
| Property Type | Common Window Needs |
|---|---|
| Retail storefronts | Glazing visibility, entrance coordination, thermal performance |
| Office buildings | Daylighting, noise control, phased installation around tenants |
| Multifamily buildings | Durable, low-maintenance units across multiple openings |
| Industrial facilities | Larger-format glazing, security, weather resistance |
| Institutional buildings | Code compliance, safety glazing, scheduled installation |
Storefront glazing shapes the first impression customers get of a retail business. We work to keep pedestrian-facing glass clear, secure, and well-sealed, while coordinating installation around business hours in active commercial corridors.
Office window replacement often needs to happen with tenants still working inside. We schedule installation to limit noise and disruption, with attention to daylighting and sound control that matters in professional and medical settings.
Apartment buildings, warehouses, and institutional facilities each bring their own scale and scheduling considerations. Some larger or more specialized projects may call for additional design review or coordination with other trades, and we're upfront about when that applies.
Matt Kulhanek founded All Access Builders LLC in 2003, and the company has worked across Western New York’s residential and commercial construction landscape ever since. We’re licensed and insured, and every project comes with a written scope of work before anything begins.
Buffalo's building stock spans everything from century-old storefronts to newer commercial construction. Understanding how different eras of construction handle window replacement helps us plan projects that account for what's actually behind the wall.
We coordinate installation timing with property managers and tenants to limit interruption to daily operations. That includes phased work plans, clear site access arrangements, and safety barriers that keep occupied spaces secure during construction
Every estimate from All Access Builders spells out the scope of work in writing, and our workmanship warranty is documented and reviewed with you before work starts. We confirm manufacturer warranty terms on the specific products used on your project, since coverage varies by manufacturer.
Step 1
We start with a site visit to measure openings, assess existing window and frame conditions, and document any signs of water infiltration or structural concerns.
Step 2
Based on what we find, we recommend window systems and glazing options suited to your building, then provide a written proposal covering cost, materials, and estimated lead times.
Step 3
We test window operation, inspect seals, complete a final punch list, and walk you through your warranty documentation before calling the project done.
Step 4
We test window operation, inspect seals, complete a final punch list, and walk you through your warranty documentation before calling the project done.
As of October 2026, commercial fenestration projects in New York fall under the 2025 Energy Conservation Construction Code of New York State and NYS ASHRAE 90.1-2025. These codes set performance thresholds for U-factor and SHGC that vary by building type and climate zone. We account for current code requirements, not outdated 2020 standards, when specifying window systems.
Certain locations in a commercial building, such as doors and low-level glazing, require safety glass like tempered or laminated products under applicable building codes. Accessible routes near entrances may also factor into storefront design. We review these requirements on a project-by-project basis rather than assuming a single specification applies everywhere, and we follow standard jobsite safety practices consistent with OSHA guidelines throughout installation.
Many commercial window projects in the City of Buffalo require a permit through the local building department, and buildings within historic districts may need additional design review. We confirm permit requirements for your specific address and scope before work begins.
Several variables shape the final estimate, including:
Our written estimate covers site measurements, labor, materials, removal of existing windows, finishing work, and warranty terms. Permit costs, where applicable, are addressed as part of project planning. If we find unexpected substrate damage once work begins, like rotted framing behind an old window, we'll flag it and discuss next steps before proceeding.

Our project photos reflect completed commercial work across the region, not stock imagery. We’re happy to share examples of storefront, office, and retrofit projects relevant to your type of building during your consultation.
This single-story addition was built with oversized black-frame picture windows, a pair of full-lite French doors, and angled transom units set into the gable. Openings of this size call for accurate rough-opening framing, properly sized headers, and careful flashing so the glass stays square and weathertight through Buffalo winters.
With the wall opened up, our crew framed new window openings beneath a steel beam, installed insulation and vapor barrier, and staged the replacement units on site before setting them. Working from the framing out lets us correct the openings, seal the perimeter, and close the wall with the insulation continuous around each window.
On this two-story addition, the window openings were framed and the structure was wrapped before any units went in. Getting the house wrap and sill flashing right at this stage is what keeps water out of the wall cavity once the windows, trim, and siding are installed.
Property owners and managers who’ve worked with us describe clear communication, organized scheduling, and workmanship that holds up over time.
Neighborhoods
Business districts along Elmwood Avenue and Main Street often call for storefront glazing work, while older commercial buildings throughout neighborhoods like Allentown and the West Side sometimes need building-envelope retrofits to address aging frames and failed seals.
