Last summer I used Zen Windows to replace most of our windows and they were great!…read more I am going back to them again now to replace the remaining windows that we skipped last time. I would recommend them again and again, I am very pleased with their work - very professional and quick installation.

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!

I cannot say enough great things about Joe and his team. From day one Joe was very professional,…read morepunctual and responsive. Windows were over 60 years old and had to be replaced asap! Joe explained the whole process from start to finish and also provided recommendations for external trim - game changer! His pricing was consistent if not a tad cheaper than six other quotes I got. His crew covered everything with plastic (Dexter vibes) to make sure furniture did not get damaged. They also cleaned every day before leaving, not just my unit but also neighbors windows and the street - wow! I could not recommend Boston Doors and Windows more! This was my first "big project" experience and I could not be happier! Thank you thank you thank you!

Great experience on all fronts!…read more I was looking to replace an old door inside my individual condo and my HOA was also looking to update a 110 year-old door and frame to our building that had been giving us some issues as it aged. Joe was very responsive, showed up on time, explained everything he'd on both projects like a pro, and he also gave the best quote we received. Hiring him was easy, especially when we saw how positive all the reviews are on him here as well. Joe was in communication with us on what we needed to do, helped guide a novice in me on what type of lock sets to buy, arrived on time and completed the jobs even faster than I expected. The results are great, as seen in the "Before and After" picture included in this review. I can't recommend him enough and when we need any future window or door work we'll definitely go to him again.

This past summer I had a decision to make on siding a small Cape in Andover. There was a tenant…read morefamily with young children living in the home and it was important to me that the work be done well and safely. O'Sullivans price was higher than some but it was very obvious that the quality and workmanship was also going to be much higher. When the work was completed I was very delighted. Tenant told me he had to pick up nails off the driveway. When I told the crew chief this they were over in about an hour to sweep the driveway and the yard for nails. Good decisions often lead to good outcomes and as fate would have it the tenant family wanted to buy the house after it was cited so beautifully. It is now their property and the warrantees have transferred to them for lifetime service.

I had O'Sullivan Installs put siding on my house almost 3 years ago. Shortly after install a few…read morepieces began to warp. I contacted Tim (owner) to report the issue. He told me he would send someone out to match the prices to replace the warped pieces. The exact lot cannot be matched and Tim told me that it would be a warranty issue with the manufacturer. He told me this about a year ago! It is ridiculous! Tim is hoping I forget about this while keeping my money and not standing by his promise. I would not recommend using this company.

Contacting them is easy, place your call or email and it will be returned in a timely fashion. They are polite, patient, provide quality products and do not take short cuts. Dracut window and door provided exceptional value in both products and service. Your window or door will be installed efficiently and with perfection. This is the second time that I used Dracut Window and Door. The first was to install a storm door in a very old house where there was no storm door. They found that the entryway measurements were not even. They did such a great job on replacing the entire entry way correctly that you would never know there wasn't a door there to begin with. No drafts, no leaks, totally an upgrade in energy perfection and efficiency! They provided the same top rate service the second time I called them to install new windows. Steve measured my windows with skill and accuracy. He noticed that my current windows were a half inch to small and had no installation around them. I mentioned this to you because the previous windows in the home were also energy efficient- however that energy was lost because they were never correctly at that time. I saw if you are looking for quality work and with a company you can trust CALL Dracut Window and Door. See for yourself and I am sure that you will be just as happy as I am!
