Old windows shouldn’t leave you guessing. Too many homeowners deal with drafts, rising energy bills, and installations that don’t hold up—often because corners were cut or work was handed off to subcontractors. The result? Frustration, unexpected costs, and a home that never feels quite right. You deserve a window project that’s clear, reliable, and done properly from start to finish.
We do things the right way – even when no one’s watching.
We don’t believe in cutting corners or passing work off to the lowest bidder. Every project is handled by our in-house team, using trusted products from long-term manufacturing partners.
I was referred to Capital Glass by a friend and based on my experience with them, I will gladly keep the referrals going! It was a pleasure to work with them. Everything was prompt, from first requesting a bid, to scheduling the installation.

Matt at Capital Glass runs a top-tier operation. From start to finish, the entire process was smooth, professional, and impressively efficient. Communication was clear and consistent, timelines were met without delays, and the quality of the work really speaks for itself.
What stood out most was how organized and responsive Matt is—he keeps things moving without cutting corners.

I have a 30 year old Anderson French door that had difficulty opening and closing.
I called Matt and he walked me through the adjustment process and sent me a YouTube with instructions.
Following those instructions the door has never worked easier. Matt was more than happy to guide me through the process even without any monetary benefit to him.

Our work
We specialize in both commercial and residential projects
We can handle all of your window needs: residential, commercial, and new construction too! We take great pride in our installations. The installation process begins with removing your old window and preparing the opening for the new one. This is done by cutting around the exterior of the existing window to expose the nailing flange.
