Diamond Construction Inc

Absolutely fantastic experience. Great workmanship. Answered all my questions. And met every expectation. Large crew and finished in a day and a half

The remodeled bathroom is beautiful. Diamond Construction took on a job that other contractors refused to attempt due to its complexity, and did a fine job.

We had our decks demolished and rebuilt by another contractor earlier this Summer. Said contractor, in the process, removed significant portions of our vinyl siding and was not able/willing to replace them. I reached out to numerous Boston-area vinyl siding contractors, only to have almost 100% of them tell me the "job was too small" for them to consider. I was becoming concerned that nobody would be willing to replace our siding when I found Diamond Construction. John came out to assess the project and our needs and spent time speaking with us about the scope/execution of the project. We made him aware of our budget, and he was sensitive and responsive to our financial limitations. The work was completed in a professional, workmanlike, timely manner. John and his staff (Erika and the crew) maintained great communication throughout the entire process from the before we even signed the contract all the way through the end of completion. We were extremely pleased with the results of the vinyl siding repair/replacement performed by Diamond and plan to use them again in the future to replace an old bay window in the front of our apartment, as well as our old sliding glass door in back, once our budget permits. We will also recommend Diamond Construction to friends and family. They are consummate professionals who value their relationships with customers and go above and beyond to ensure projects are completed to customers' satisfaction. Thank you!

Prompt response letting me know that they are not performing this service at this time.

The owner (I believe) came out to do the estimate. He seemed knowledgeable and was nice. I just couldn’t get the estimate after sending messages through the Angie’s List app and even texting. I couldn’t get a response and it has been almost a month. It is a small job so I guess it isn’t important to them. Also hard to say if I would hire again since I never got to make the decision.

Outstanding! Where here on time every day and completed the main project in two days. I had them replace numerous shakes on the house and six rotted window sills so that took a few extra days.

John and Laize from Diamond Construction were great. Excellent communication from start to finish. John and his crew arrived prompt and worked very hard for one and half days to complete my roof and skylights. It was a large roof on a two family house and it came out beautiful. Clean Up was good also.

They came to my house as promised. Job done quickly. Looks good.

Diamond construction company replaced our homes roof and skylights. From start to finish their work was extremely professional and honest and high-quality. Dear owner John walked us through the overall proposal project plan and a economical budget. Dear team work very hard and completing projects on time. Thanks to diamond our house now looks very beautiful from the outside and the comfort level inside the home is much better . We would strongly recommend diamond construction for any home improvement project .

The President and owner, John Malo, had come to my house in late January and gave me a very reasonable quote for the project. We scheduled the work for March 27,2019 but due to weather it was started and completed in just one day on 4/10/19. John had quoted me a price per plywood sheet if there was a need. When they revealed the existing plywood, John called me and said it is all 1/4 inches and is supposed to be 1/2 inches. I gave him my approval to correct this. Still, a reasonable price. They were very organized and did an excellent job and cleaned up. A dumpster was brought in a day before and removed a day after. I am very pleased with the exceptional job they did and would use them again for other projects.

It was professionally done and the customer service was great. The price was very moderate too.

I got several quotes from different roofers before I chose Diamond. John came by himself and gave me a very detailed description on almost everything, from materials they're going choose to the warranties. The price was also the lowest among all quotes. They did a good job overall,. I didn't give the highest rank for quality because some details could have been improved. I noticed the wall siding was not perfect handled, maybe because it was dark at the time when they're about to finish the job.

Roof was replaced; it was done in one day. They crew were very professional and cleaned up after they were done. I am very satisfied with their work.

John, Laize and team were great to work with. They provided a fair quote for the work and the job started on time. We added on some extra work to the project once it started (we planned for a new roof and then had them replace some siding on the back of the house). They were diligent in doing the work and keeping us updated on progress. They did a few extra things for us while there (fixed some shutters and a few boards on our deck) which was super helpful. They cleaned up thoroughly when done and John was very interested in ensuring we were satisfied with the work. We did a complete walk around the house with him once everything was done before paying the balance and he made sure we were totally satisfied. We would certainly recommend them to others and use them again.

Excellent job done. John was very nice,he explained everything from the start of the project.His crew did a nice job and finished the job in one day even thought the weather was bad. The cleanup after the job was very good.

John Malo, the owner of the company came out to give an estimate. He suggested this could be paid by our homeowner's insurance and helped us through the process of submitting a claim and providing supportive documentation. The team kept us informed of each step of the process. They were always puctual and responsive to any communication. The job was done meticulously, and in the promised time-frame. The crew was respectful and hard working. I would highly recommend this company.

Ciro and Rosa were wonderful to work with. They were honest, good communicators and worked incredibly hard to get my roof and my chimney done on time. They responded well to my questions, and let me know what was happening. I particularly enjoyed working with Rosa-- she was professional and really knew the work, worked incredibly hard herself and was easy to talk to...As a female home owner, it was particularly great to work with a woman foreperson as I have found that men who I have hired talk down to me, assume I don't understand the work or don't answer my questions clearly. Rosa was terrific-- she contacted me quickly with any changes, and explained everything to me in detail, showed up early and stayed late. My roommate also loved these guys so I didn't have to worry about them bugging anyone in my household. Overall, it was a really good experience and both the roof and the chimney look beautiful!!

They did good work, on time and hardworking crew, completely new roof and new deck. Removed and hauled away no mess. Very satisfied and will use them again. They did work for my parents and they are happy with their jobs as well. Karen M.

We had set an appointment, and they never showed up or called to cancel/re-schedule

They were great and easy to communicate with. Prompt and completed on time as quoted.

This company was responsive during the estimation phase of my job. They arrived on time for the initial appointment and gave a good impression. They were also on time for the signing of an incomplete, one-sided and typo-filled "contract" and to pick up their initial check. (They also placed an advertising sign on my lawn without permission.) This was a "small job" (to them, if not to me) and they were busy on, I guess, more important jobs. So in early August, 2018 we set a date for early September to do the work. On the morning of the agreed-upon date, I called the company when they didn't show up. It was clear they had no idea who I was. When I asked if they knew where my house was, they gave me the name of a town 20 miles from here. They offered a variety of excuses in the vein of, "My dog ate the homework". In this case it was the weather, When asked why they didn't know a day or two in advance what the weather was going to be so they could email or call, they apologized. After that, they promised to keep me updated. That generated a series of emails that were either odd or badly timed. In one case that someone in the office emailed me a weather forecast, as if I wasn't able to find it myself. Another time, they emailed me at 10pm to say they weren't going to do the job on the day that had just ended. Finally, I received an email that they be doing the job two days in the future, when fine weather was forecast. Instead they showed up the next day, while it was still raining -- though it did clear up eventually later in the day. As to the work itself, the guys who did the work worked hard. But they showed up not knowing that the job was to replace two length of both soffit and fascia boards (a call to the boss apparently cleared that up), Materials for the job weren't purchased in advance. The soffits were supposed to be vented but what was installed wasn't (I didn't make a big deal about this). So, one has to wonder what the work quality is like. Since I am too old to climb a ladder to the highest points of my two-story home, I can only use visual clues as to the quality of the work, In one case, the workers re-hung a gutter that was bowed in the middle, meaning any rain would pool in the center of the gutter. They fixed it after I pointed it out, of course, and they didn't make the same mistake on the other length of gutter. But I wonder what the work was like on areas I can't see from the ground. Bottom line: they were hard to work with and the quality of the job is suspect. Avoid.

Very well. They came when they said they would, completed the job as planned and the leaks stopped! They were also informative about how to care for my attic. Another pro recommended complete roof replacement , but these guys correctly diagnosed the cause of the leaks and made the appropriate repairs for a lot less money than the other company.

These guys were quick, diligent and professional. I’m and out in two days. A job well done.

Diamond contraction Inc. replaced my home roofing at Lowell MA. The employee showed up on time and working hard to get it done as well. the team are organizer , cleaned up all times when they finished. John and Laize easy to communicate and very nice. My roof look nice now with solar vent and ice panel. Today have severe thunderstorm for the new roof test, I have check all around , no leak at all! I am so happy, it is very good company!

Ciro and his team did a fantastic job from start to finish. They took care to clean up after finishing the job. We are very happy with the work they did, they exceeded our expectations.
