Full-frame and insert replacements, measured to the sixteenth and set square. Quieter rooms, warmer floors, and considerably more light than you remember being in there.
One room, photographed in the afternoon once the trim went on and before anything got moved back in. We post the light rather than the product β the light is the part you live with.

Measured, ordered, installed and trimmed by the same two people, start to finish.

Vinyl or fiberglass, insert or full-frame depending on what the opening will actually allow. Measured to the sixteenth, shimmed square, foamed low-expansion and trimmed.
From $745 per window
Fiberglass or steel slabs hung in a new frame, with the jamb re-plumbed and the threshold set so it seals without needing a shoulder in it.
From $3,250
Sliders and French units set on a properly levelled sill, so they still roll with one finger in year six the way they did in week one.
From $3,900
The big one on the front of the house β framed, headered, insulated and roofed properly, rather than caulked into an opening and hoped for.
From $3,400
Cut, framed and set to size for a basement bedroom, with the well, the ladder and the cover set outside while we're there.
From $4,600
Full-view storm doors, retractable screens and screen rebuilds. Inexpensive comfort, usually done inside an afternoon.
From $865Photographed in the afternoon, with nothing moved back in yet.








Northlight started in 2015 after fifteen years of hanging other people's orders on other people's schedules. Aaron wanted the person who measured the opening to be the same person who set the unit β a small idea that turns out to fix most of what goes wrong on this kind of job.
So that's how it works here. We measure, we order, we come back and set them. Nothing gets subbed out and nobody hands you off to a crew you've never met. We're slower than the big outfits and we've made peace with it β four windows done right beats fourteen done Tuesday.
β Aaron Vail, NorthlightThree things that are very difficult and very expensive to fix afterwards.
Same hands on the tape and the shims. Nothing gets lost between a salesman and the van.
Most people notice the noise before they notice the draft. It's the first thing you'll hear.
Flashed, foamed and caulked in the right order, so the wall behind it stays dry.
Glass, sashes, packaging and trim scrap all go out in the van the same day.
