"Bob was able to repair the 3 doors in my home that were not closing correctly. Additionally he had time after the initial repair and was able to fix a few other doors that were also giving me some problems. You can tell by the quality of his work that he is very skilled and experienced."

"When we started our plan of remodeling, the first thing we did was the complete roof replacement including kitchen vent & duct pipe installation to the roof, and new installation of attic ventilation. MMP did not only completed it just as agreed but also very efficiently. The crews were friendly, professional, and careful. The jobs were carefully managed and implemented effectively. I was impressed by Matt, who is the manager, and he does an outstanding job in managing the crews and the progress of the situation, and the communication was clear and always to the point. We then moved to initiate a search for a contractor of two bathrooms remodeling after completing the roof and attic vent, MMP was one of the many candidates. Matt has had not only the best idea and proposals but also shown an impressive & professional sense of evaluating the project accurately, including the possible structural modification as well as a competitive estimate of the cost of the build. His proposal included a rebuild of a wall of the bathroom to expand another one adjacent to it. Matt accepted to use my schematic design image (made with a software tool) and a spreadsheet list of the fixtures that I created - as many as fifty items including TOTO, Grohe, American Standard, Panasonic, and IKEA - to start the job (later changed some of them due to local plumbing code compliance) After beginning the bathroom remodel project, Matt shared what jobs will be done with us timely and efficiently via text so that we feel comfortable enough in knowing what is going on while living in the house of dust & noise from remodeling. The crews, Zen and Mark, were very courteous, extensively experienced, reliable, and friendly with excellent communication, sometimes with songs of 80s rock music. They ask me when more precise specifications are needed and notified me when they feel advance notifications are required. When a change is necessary due to inspection, they informed me and clarified what and why. I have never felt uncomfortable in living together with the remodel job which has lasted over four months. The completed two bathrooms were stunning, just as I imagined. Matt, Zen, and Mark have proved their strong & thoughtful expertise and lived up with my request patiently until completion. Great job. A home remodeling project cannot be successful without having a trusted partner, and my experience with MMP has led me to be glad to share my confidence that MMP has a credential to become your reliable partner to manage a construction project together."

"The project went great. On time and within budget. John and John did all the work necessary to remodel a master bathroom, a half bath and a laundry room. This included all the demo, floors, walls, cabinets, plumbing, electrical, shower, tile, painting, etc. Excellent job and we will definitely use them again for our next project!"

"This was our first time using them. We found them on the internet then gave them a call to put an addition on. Everything turned out beautifully. When we called to get pricing and talk about the job they were very friendly and accommodating. They made the process seamless! Their pricing was very reasonable. The workers were prompt, polite and professional. They were very courteous and they were respectful of our home. They also did a great job of being tidy and cleaning up after themselves! I will have to remember next time that remodeling is a bit of a noisy process, but I can handle the noise for such a beautiful outcome! You will not be disappointed!"

"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"We were very happy with the price, product, and process that DiOrio delivered for our project. We had a fairly extensive remodel that required a near demo of our second floor in addition to a complete bathroom remodel with an extended floor plan. Derek & James estimated 2 months for the project and they hit that within about a week, which was appreciated because I know these projects can drag and we were temporarily living offsite. James did most of the work on our project, with support from others as needed. He's a talented carpenter with broad knowledge and good attention to detail. Communication throughout was truly excellent, which is also extremely important for a project with lots of moving parts. Construction projects are typically not typically "fun" but these guys are highly skilled and they work fast. Go in with a clear idea of what you want, realistic expectations (especially if you have an older hours), stay organised, and you will be very happy with result. We would definitely work with DiOrio again."

FAQs for addition and remodeling projects in Nashua, NH

The proper sequence of a kitchen installation starts with laying the foundation and structural framework. From there, you need to establish utilities like plumbing, wiring, and gas lines, then install cabinetry and countertops, and finally finish with flooring, painting, tile backsplashes, and lighting. A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
