Why AVI for your windows

Properly flashed, sealed and finished right.

Every window and door we install is measured, flashed and finished by the same in-house team — no subcontractors.

No subcontractor guesswork. The crew that quotes your windows is the crew that installs them.

02

Quality workmanship

Careful, code-correct installation by our own crews, with manufacturer coverage on frames and glass.

03

Energy efficient

Low-E insulated glass packages that reduce heat transfer and help lower heating and cooling costs through every PA season.

AVI replaced every window in our house in one day. The difference in noise and drafts is night and day — we can actually sleep through garbage truck mornings now. Clean, professional, zero mess.

Beautiful new steel entry door with sidelights. It completely changed the front of the house. The crew was here by 8am and done by noon — perfectly plumb, perfectly sealed. Highly recommend.

Our old patio door leaked air something terrible every winter. New sliding door from AVI — installed right, sealed tight. First winter in years we haven't felt a draft in the family room.

The new bay window in the living room is stunning and the seat they framed underneath is now my favorite spot in the house. Tidy, precise work and they hauled away every scrap of the old frame.

Replaced eight windows and two storm doors over two days. Everything opens and locks like butter, and the house is noticeably quieter and warmer. Straightforward pricing, no pressure at all.

Windows & Doors FAQ

Good questions, answered.

Still unsure? Talk to a real person — no call center, no pressure.

Double-pane is the standard for most PA homes — a great balance of energy efficiency and cost. Triple-pane is worth it for rooms facing prevailing winds or north-facing walls where heat loss is highest.

It depends on window count, style and glass package. After a free on-site visit you get an itemized, fixed quote with no surprises — and we offer financing options.

Most full-home replacements are done in one to two days. Individual windows or doors often finish in a single morning with no disruption to your schedule.

Yes — energy-efficient windows with Low-E insulated glass reduce heat transfer significantly. Most homeowners in Lower Bucks County see a noticeable reduction in heating and cooling costs within the first winter.

We stand behind our workmanship with careful, code-correct installation. Windows also carry manufacturer coverage on frames and glass packages — we'll walk you through the specifics before you sign.
