Professional Window and Door Installation in Connecticut

ES Custom Construction is a licensed window and door installer in Connecticut. We provide professional window and door installation services on residential projects in Connecticut, including replacement windows, new construction windows, entry doors, patio doors, sliders, and storm doors. Every unit gets set plumb, level, and square by our own crew.

Our window installation crew handles every step of the work in Connecticut. We pull old units out clean, square the rough openings, shim and fasten new windows plumb, seal with proper flashing tape, and trim out the interior and exterior cleanly. Connecticut weather seals hold up to winter pressure.

As a Connecticut window and door contractor, we cover Danbury, Stamford, Norwalk, Greenwich, Fairfield, Westport, and the rest of the area. You hire Edwin and the crew direct. No call center, no door-to-door sales pitch, no installer subcontracted out at the last minute on install day.

Every window and door we install in Connecticut gets the same standard: rough openings squared, flashing tape lapped right, fasteners set to manufacturer spec, and the trim cut to close up clean. Connecticut homeowners hire us because windows installed properly stop drafts, leaks, and call-backs.

Why Connecticut Homeowners Choose Our Installation Crew

Plumb Every Time

Every window and door we set lands plumb, level, and square. Latches, locks, and tracks work because the unit was installed right.

Weather-Tight Seals

Connecticut winters test every flashing detail. We tape, seal, and trim every opening to keep cold air, water, and drafts out year-round.

One Crew, One Job

You hire Edwin and the crew direct. The installer measuring on day one is the same person setting windows in the wall.

Window and Door Installation FAQ

How long does window installation take?

Most window swaps run one to three days on a standard home. Bigger jobs with twelve to twenty windows, or new construction openings, can take a week. Door installs add half a day to one full day per opening.

We install most major brands, including Andersen, Marvin, Pella, Harvey, and Provia. We can also frame and install custom or specialty units when the project demands it. Bring us the brand you want or ask us to recommend one.

Yes. Most window swaps in Connecticut do not need a permit, but new construction openings and egress windows usually do. We pull whatever is needed and coordinate the inspection with the local building department.

Yes. We match grid patterns, sash colors, frame finishes, and trim profiles whenever possible. Bring us a photo of the existing window and we will spec a unit that matches close enough to look uniform from the outside.

We handle those carefully. Lead paint requires EPA RRP protocols, which we follow. Rotted framing gets cut back to solid wood, new bucks installed, and the rough opening squared before the new unit goes in.

Costs depend on unit count, brand, glass package, and openings. Standard double-hung replacements run on the lower end. Patio doors and custom shapes cost more. We give itemized quotes after measuring, no guessing on price.
