Niagara County's Window & Door Contractor
Express Windows Inc. is based at 3495 Delaware Ave in Buffalo — just minutes from the Niagara County line. We've been serving homeowners throughout Niagara Falls, Lockport, and the surrounding communities with the same energy-efficient products and honest pricing we bring to every job in Western New York. No national call centers, no subcontractors — just our own trained crews doing the work right.
Niagara County Communities We Serve
From the gorge to the farmlands, we cover all of Niagara County.
Niagara Falls
Niagara Falls homes face some of the harshest wind and moisture conditions in Western New York — sitting right on the Niagara River gorge means your windows take a beating year-round. We install energy-efficient vinyl windows and insulated doors built to handle it.
- Wind-rated window packages
- Moisture-resistant vinyl frames
- Entry & storm doors
- Free in-home estimates
Lockport
Lockport's older housing stock — much of it built in the early-to-mid 20th century — is exactly where replacement windows make the biggest difference. Swapping out single-pane originals for insulated double or triple-pane units cuts heating costs dramatically.
- Double & triple-pane windows
- Full-frame replacements
- Vinyl siding
- Same-day estimates
Lewiston
Lewiston's historic village and surrounding neighborhoods have a mix of older character homes and newer builds. We offer custom sizing and grid patterns to match the architectural style of your home while delivering modern energy performance.
- Custom sizing available
- Grid & colonial patterns
- Entry & patio doors
- Manufacturer warranties
Youngstown
A small village at the mouth of the Niagara River, Youngstown homes are exposed to lake-effect wind and cold. Our insulated window and door packages are a natural fit for homeowners here looking to improve comfort and cut utility bills.
- Insulated vinyl windows
- Storm doors
- Energy Star certified
- One-day installs
Wheatfield & Pendleton
Growing suburban communities in Niagara County where newer homes and established neighborhoods both benefit from quality window and door upgrades. We serve the full length of Military Road and beyond.
- Casement & double-hung windows
- Fiberglass entry doors
- Vinyl siding
- Competitive pricing
Niagara Falls suburbs
From Sanborn to Wilson and throughout rural Niagara County, we travel to serve homeowners who want the same quality installations we deliver closer to Buffalo. No extra travel fees.
