The window had to be ordered & they were in touch with updates along the way which is very important as I'd never used them before and had paid 50% deposit . They were very very professional & polite & easy to have there doing the work when the work was being done .

They truly became like family by the end of the project and we are so very grateful to have found them. Like with any construction project, there were unexpected things along the way, and they handled them with care and attention as well as clear communication. I felt like they treated our home as they would treat their own. We felt we could trust them to be honest and fair throughout the entire process and that was priceless. I would highly recommend their services for all your Home renovation needs! We couldn't be happier with our investment and with the experience we had working with them. The attic looks fantastic. My two year-old has seen their truck in the neighborhood and said "When are the guys coming back to work on the house?" :)

You ever have a basement window just....sporadically shatter for no apparent reason? Well,…read moreevidently this is just a thing that randomly occurs in this part of town. The last time I had glass shatter spontaneously was back in '24 when our winter storm door screen was completely pulverized by the summer heat, it seems (Pro-life tip: swap out your storm door screens in the summer with mesh ones). On the back of that unforeseen devastation, out went my mass inquiries to all the local shops servicing the Nashua area. Out of maybe 5 (?), 3 responded almost instantly. One sent a quote so high, I was half tempted to reply and ask if I could have some of whatever they were smoking. Another replied with what seemed to be a promising rate, but there was one problem. Their communication was severely intermittent to the point where they inexplicably ghosted me faster than a recruiter responding to a job applicant. Ultimately, I settled on Good Window Works. They offered a fair quote, were easy to get ahold of, and even provided a COI statement as per the request of our housing board. For those unaware, a COI is a Certificate of Insurance. Basically, it's assurance to the board that the contractor in question is insured to complete the job without creating a liability if they, say....jam their thumb beneath a tack hammer or something. With those formalities out of the way, the job was simple enough: Replace the half of the basement window that abruptly disintegrated. All in all, the job took roughly 2 hours. In the end, the window he installed was so transparent, it looked like there was no pane at all in the frame. But no--the glass was just THAT pristine! I don't say this often, but....experiences like these are what I love most about being a Yelp writer. So rarely do I get to be in the position to not only promote another hard working local business, but also pose as the microcosmic advertising vehicle that just might serve as the prompt some very fortunate individual needs to go, "Yeah, I'm hiring this place to work on my house". If you're wondering whether you should hire these guys for your next installation or repair job, the answer is likely yes. Good Window Works is worth 5 window panes clearer than thin air out of 5.

Only Good Windows responded and sent someone out to do an estimate. They just finished the job. The original estimate was done from the ground, however when the technician was able to get the unit out of the frame, (This is an old style window), we both saw that additional work had to be done. The tech did the work and did an excellent job. It was only a bit more over the original estimate, but quite reasonable. I highly recommend Good Window Works.

A massive waste of time. We called and made an appointment with a salesman. On the phone we told…read morehim we were looking for European style doors or something a little more modern styled. He said they sold Marvin doors and that I could look on their site to see if they had the sort of style we were looking for. On the Marvin site they did in fact have the kind of style we were looking for. We came in for our in-person appointment, the salesman showed us French doors, not really what we were interested in so I showed him the Marvin site. He said "we sell Marvin doors but not TruStile." Apparently TruStile was bought by Marvin but for whatever reason Affordable Windows and Doors doesn't sell particular lines in a brand they carry? He didn't offer up any alternatives in a similar style from perhaps another door company and made no attempts to actually help us find something in the style we were looking for. He basically showed us one French door, told us we don't sell doors like the ones on the site he told us to go look on and that was it. Guess I'll order from the door company directly.
