We signed with Zen Windows at the end of July after being told--in writing--that installation would…read morehappen within 4-6 weeks. It's now mid-November, and not only are the windows still not installed, but the installation date was just pushed again to mid-December--almost five months after signing. We specifically reviewed the timeline because we wanted this done before it gets cold. We have booked dog daycare which has to be rescheduled, it affects our schedules, plans, and will massively impact our work, which is WFH. The measuring process was chaotic. The person sent to measure always gave last-minute notice and had to come out multiple times because they kept miscounting the number of windows--always short by one. Communication throughout this process has been terrible. You have to constantly follow up for updates; Zen never reaches out proactively or takes ownership of delays. Every update comes only after you chase them. When we brought up these issues, the company's response was to blame the original sales rep, who is "no longer with them." Convenient excuse, but the timeline and promises were in writing. Zen has taken no accountability for the misinformation or poor service. Yes, they may be cheaper than competitors, but you truly get what you pay for--unreliable timelines, lack of professionalism, and customer service that's downright egregious. Buyer beware!

We were very concerned that so many contractors would not be experienced enough to deal with the challenges that a house, built in 1753 would naturally have. Dave and Mike came into an absolute mess with our post and beam construction since the damage to the fieldstone foundation impacted the entire house. They did a fabulous job, better than any of our expectations. Whenever they encountered a problem we thought would be insurmountable, they calmly figured it out; even as our house was then effected by the Columbia gas explosion, right in the middle of construction. Dave gave us good advice, made solid suggestions on how to maximize our insurance money and was calm even when we were not. The communication was quick and clear even with the other contractors. This was an unbearable situation made bearable only because of Dave and Mike's professionalism, honesty and patience. Highest recommendation for HRH Construction

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.
