My initial conversations with Colin were pleasant -- he said all the right things. The problem was the quality, or lack thereof, of the work performed. I had assumed I got the B team but based on the comments here, it seems this is the work one should expect. Several of the windows leaked. The door installation was a complete disaster with hammer marks left all over the trim. To top it off, on several occasions, I smelled marijuana while the installers were working on my home. Stay away!

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.

Other companies told me not really feasible to fix financially, tried to sell me on new door,sensors and new opener when opener only 2 year's old. This man with Eastgate cleaned sensors, and webs were main reason not working right so recommend I used little paint brush once week to just keep from problems, got a latter,within 30 minutes a few adjustments and brand new working condition. I quote, well ma'am that's the difference between my company and others, my name is everything. My motto is quality over quantity. Yes I have bills to, but I'm in business to stay in business, not to just replace door's that don't need replacing. Garage door's as well as commercial door's are like anything else we have, everything needs maintenance. Things like this needs cleaning,parts replaced from usage and it's also subject to weather. Wow, take a moment to absorb that. I was charged a service call and for a couple small part's, but he didn't charge labor,surcharge, and other charges on my other estimates from other companies. I hope he stays around a long time. I will never use anyone else. Honest was understatement. 2 other neighbors came over seeing him at my home and two more job's because of reasonable, trusting and great feeling of not being taken advantage of. Funny he was on vacation and took care of us on his Time with family but did all three of our door's in about 2.5 hour's. So get estimate if you want, but as we were talking only thing he can't get is huge discounts like bigger corporation do, but after seeing what he charges and others still better deal because if new door is needed he tries to lower cost of service call or gives credit to referrals. So because of other neighbors he didn't charge me for service call. I'm so happy with door now, opening and closing faster,smoothly, omg much more quiet. So if you want to throw money away and support corporate companies taking advantage and charging double what they pay for doors and surcharge ect..save yourself a headache and call this small business owner and support honest,hard working American knowing he's not trying to go out of business. You won't pay for anything you Don't need. Even takes time to show you why, or what your parts look like compared to new part, explains how and why they wear out. So excited. ..everyone else made me think it was going to cost me $2000 - $2500 when after discount barely cost me $120. And other saved at least $1000. That's huge difference. Give him a shout I'm sure you'll be just as excited. Thanks Bill for your great work and kindness a long with all your years of experience we had talked about. Good luck with business. I won't hesitate spreading the amount you saved me and educating me on how to avoid costly repairs. Thank you so much.

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!
