  • "Could not recommend Harmony highly enough! I recently had recurring wind damage to my roof (installed by a different contractor), which ultimately required a complete roof replacement. Harmony stood out from the first conversation. Dennis was extremely responsive, prompt, worked up a thorough and competitive proposal, and literally went out of his way to assist with the insurance claim. Perhaps most importantly, however, it was the overall customer experience - their attention to detail, low pressure approach, and competence and professionalism - that left you feeling like they were more concerned about servicing the customer than just getting another sale. Suffice to say, the new roof looks great! Harmony will be my first call for any future exterior home improvement projects!"

    - M.F, Jul 6, 2021

  • "We recently had new windows, siding, gutters, and doors installed by Harmony Home Improvement and we couldnt be happier! Our home looks so updated and beautiful! Dennis is very professional and wonderful to work with. He took the time to explain all products thoroughly, and the selection of quality, reasonably priced products was exceptional. He was always available and responsive throughout the process. We are very happy with the quality of work and highly recommend Harmony Home Improvement!"

    - L.M, Jul 5, 2021

  • "I highly recommend Harmony Home Improvement for roofing, siding, and residence upgrading/repair. From my initial meeting with John Kavanagh until all projects were completed, he was always attentive, accessible and courteous. John listened to what we wanted to be done and was very accommodating. He sent us quotes for different scenarios we had envisioned with and without a number of items, such as: roof replacement, siding replacement, and upkeep needed for the house such as shutter and screen door replacement, and minor cosmetic damage to the garage. John was patient and extremely accommodating to us as we finalized what work would actually be done, and he kept in contact with us every step of the way. As far as the Harmony Home improvement crew, they were punctual and adhered to strict safety standards and insured there was always a path of egress for us during the work areas. My wife and I do not hesitate to recommend Harmony Home Improvement to you. Their rates are reasonable for the area and for minor home improvement jobs they are willing to negotiate with you on the charges. As for us, for any home improvements we will not use anyone except for Harmony of South Windsor, Connecticut Donald Chislum New Britain"

  • "We had a fantastic experience with Harmony Home Improvement, who took over an existing deck project that needed to be reworked. My wife and I hired family to complete a pool deck and unfortunately it was not able to be finished. Upon having it inspected, we found that there were numerous structural issues that needed to be attended to in order for it to pass code. Dennis came to evaluate the job and assured us that the deck could be saved, brought up to code and made to look nice. They recently finished the work and it passed inspection and looks fantastic. Throughout the whole process, Dennis was a pleasure to work with. He was attentive to details, responsive to any questions and his team was professional, on-time and diligent. The main crew, led by Billy, has a passion for carpentry and continually expressed how their main goal was to make us happy with the project, which we are! We highly recommend Harmony!"

    - J.W.

  • "If you are looking for professional, courteous and efficacious service, Harmony Home Improvement is the way to go. They do everything they say they are going to do and it’s done a a timely fashion. The workers are mindful, constant and very clean, whatever mess they make, they clean up and leave it as if they were never there. I thought it would take days, they finished the same day they started. Dennis Bellamy, kudos to your ethics and those who work with you."

    - B.C.

  • "I am beyond happy with Dennis and his crew. I looked at many reviews and this company seemed credible. I had a good feeling from day one. I must have met with 10+ companies that put up vinyl siding. Dennis was the only one to not only be on time, but was early and had property reports for pricing, printed estimates and had already walked the property. He was personable and honest. He didn't try to sell the most expensive product. I did find a couple of companies that were less expensive, but he was willing to work with me and get as close as possible to their prices. On the first day of work he introduced the crew. The guys who worked on our home were great and did not fool around or waste time. They did their best to work around plants and shrubs and cleaned up very well at the end of the day and the very end of the job. Dennis was also very responsive to my emails and answered any questions I had. I only write reviews if I am extremely upset or extremely happy. This expensive investment was nothing but positive. I highly recommend Harmony Home Improvement if you plan on having work done to your home. Chances are it is a major investment and nobody wants to be disappointed with the end results."

    - J.P.

  • "On time for the estimate. Very fair prices. The roof gutters and windows were installed on time and done right the first time. Last but not least the owner and his crews were clean and professional. I will definitely be using them again"

    - J.M.

  • "Have you ever had someone come to your home to give you any estimates? It’s never quick and easy. Most of the time you have to listen to a hour long presentation and then get a very high quote. CALL HARMONY HOME IMPROVEMENT before you call any other company! It was fast. It was easy. It took maybe 15 minutes! They did the work before they showed up by measuring our roof using Google Earth. Harmony uses three brands of shingle with several options in each brand. Then you have the quotes based off which brand and style shingle you decide on. The pricing was perfect. Let’s put it this way: I was able to have my roof replaced, two skylights and new gutters for less than what other companies wanted to charge! Dennis is extremely easy to talk to, not pushy and very honest with his recommendations. Everything was installed in one day. The workers are very nice, professional, hard working and efficient. They made this process so easy. I would recommend them hands down to anyone who needs work done on the exterior of your home. Call Harmony first! You will have peace of mind on a job well done."

    - R.R.

  • "We had Harmony Home Improvement replace our roof and shutters and we couldn’t be more happy about the service and the product. We even had Dennis look at our deck for a repair and we learned a great deal about our deck from him. Highly recommend Harmony Home Improvement!"

    - S.P.

  • "Harmony Home Improvement put a new roof on my house and did a outstanding job. The guys were polite and conscientious, of my property. The clean up amazed me. You never would of known they had done such a big job with the exception of the beautiful roof they left behind. I would definitely recommend this company."

    - P.M.

  • "I can't speak more highly of Harmony Home Improvement. I have dealt with several building contractors over the years with mixed results. I have used Harmony now several times for windows, doors, siding and roofing. Competitively priced, professional and work done right the first time. Thank you for being A++ and will surely use Harmony again."

    - J.A.

  • "They go back on their word by canceling projects when you ask them questions. Owner Dennis told me he could not estimate price to install interior door saying there were just too many factors involved. He turned it around on me and asked me what I expected to pay. I said less than $1,000. So he sends sales guy John who immediately tells me $925 before doing any measuring or inspecting. So much for all those factors that he needs to inspect in person. Sounds like they had my $1,000 budget in mind and went straight to the top. Called Dennis and sales guys John back to see if I could save some money by buying my own door and just pay them to install it. Their response was condescending. Dennis said "were not a handyman company." John said, "we need to put our name on the project." This is an interior door, not looking for anything fancy. Not rocket science. I asked them for an itemized list to see what work they were going to perform for the price and they got annoyed and texted me that they were "going to pass" on the project which they verbally agreed to do. I guess they aren't interested in pricing transparency or answering reasonable questions from homeowners."

    - M.C.

  • "We hired Harmony to re-side our house. Dennis was professional and knowledgeable during the quoting process. They were in the same price range as two other companies we had quote the project, but were slightly lower cost. We ended up choosing Harmony because we felt most comfortable with Dennis. The siding team showed up on time everyday and only needed 3 1/2 days to complete the project. The house looks great and there were absolutely no issues throughout the entire project. We would highly recommend Harmony and will use them again for future projects at our home."

    - K.R.

  • "Professional, Responsible, and very knowledgeable. This combination is becoming more and more difficult to find these days. Dennis is a man of his word. I am extremely impressed!!!"

    - K.J.

  • "This company does not stand by their work. We purchased a home with the roof done by this company 7 years ago and there are already numerous leaks that they will not repair without charging an arm and a leg. Already have another company coming out to diagnose free of charge, when Dennis wants $375 just to diagnose his own issues. Good contractors stand behind their work, this one does not. **UPDATE** this was purchased through the Previous owner, not myself as I would not choose a company with an owner that is so rude. Luckily, we hired a very reputable company to fix your issue."

    - J.B.

  • "Just called them and they don’t do free estimates/diagnostic...$375, unheard of . WoW"

    - J.D.

  • "After 9 years of hurricanes, ice dams and falling tree branches our roof had raised shingles and pieces of plywood that had shifted out of place. Dennis and his team were highly professional and did a wonderful job securing everything down again, extending the life of our roof and making it look great in the process. I would highly recommend Harmony Home Improvement and will certainly use their services in the future."

    - R.S.

  • "I’m giving one star because the beginning was ok. Estimate guy was on time, explained everything, all the pieces seemed to be in place. Also they worked with us in terms of rescheduling the installation of the roof. Pricing wise they’re average with everyone else. Now the day of the installation. The dumpster and materials supposed to be deliver first, instead group of guys showed up and started ripping my roof in 22 degrees weather (no dumpster or shingles on site). None of them speak any English to get any explanation. They worked long after dark with flashlights on their heads. I saw the results in the morning when I found my driveway covered in old nails, and front gutter smashed in two spots. Hubby gets in the attic and see the sky in two different places (no flashing on connecting roofs), no ridge vents which according to estimate guy are mandatory and included in price Called them and one guy came back and supposedly fixed it (didn’t have chance to check it yet). Also got extra bill for 16 sheets of plywood replaced (which could be true, my roof was old), but it would be nice to see some kind of receipt/proof of that. Lastly, I had to call the dumpster company for the dumpster pick up cause they just left it behind. After two days of waiting I figured nobody is coming to get it. Sure enough dumpster comp had no clue about picking up their container. I also had to clean my neighbor’s yard covered in plastic shingles wrappers In nutshell, If I could go back I wouldn’t go with them..."

    - J.H.

  • "Harmony has done two homes for me and I highly recommend them. Very professional company. They are quick and clean up is excellent. Their prices are competitive with other companies. Their customer service is wonderful as well. Any issue after they are finished(which is rare) they will come back out to ensure the customer is happy with the service they provide."
