Window & Door Installation
Replacement windows, entry doors and storm doors, measured right, flashed right, sealed right.
A window is only as good as its installation. The best glass on the market leaks if the flashing is wrong, and a mid range window installed correctly outperforms a premium one installed on a Friday afternoon. We measure twice, flash with the right tape in the right order, insulate the gaps with low expansion foam and cap the exterior in bent aluminum so it never needs paint.
Doors get the same respect. An entry door has one job: close perfectly for decades. That takes a square frame, correct shimming, sill sealing and hardware adjustment. The blue door with the fan transom in our gallery closes with a click you can feel in your teeth, in a good way.
We install windows and doors as standalone projects or as part of bigger remodels across Lancaster and Chester County.

GOOD QUESTIONS
Questions we hear a lot
Insert replacement or full frame: which do I need?
If your existing frames are square and rot free, inserts are faster and cheaper. If there is rot, air leakage or you want more glass area, full frame is the honest fix. We open up one window with you and decide on evidence.
How many windows can you do in a day?
A two person crew installs four to eight insert windows a day depending on size and floor. Your house is never left open overnight. Every opening we start gets finished and sealed the same day.
What is aluminum capping and do I need it?
Capping is color matched aluminum bent to wrap your exterior window trim. It seals the wood from weather and ends trim painting forever. If your trim is peeling every few years, capping pays for itself in skipped paint jobs.
Can you install a door I bought myself?
Yes. We install customer supplied windows and doors regularly. We just ask to confirm the measurements before you order, because a door that is an inch too wide is a very heavy paperweight.
