Our agency found working with Principal Builders to be a painless experience. Unlike dealing with so many other contractors, Tim and Joe provided timely, professional service and the highest quality work. We are very pleased with the result.

As a facility’s manager I have dealt with more than my fair share of contractors and I can say without question Principal Builders is top on my list. I met with the partners directly as I was in a bit of a bind. I needed to get a computer lab complete over break. Tim and Joe took over the design process and handled every detail and I was kept informed throughout the process. They managed not only to complete the project on time but early and we were able to get the lab operational before the students were back. The new lab exceeded everyone’s expectation. I would highly recommend these guys to anyone interested in renovating or remodeling a space.

We could not have been more pleased with the work of Principal Builders. Joe, Tim & their team not only met our very aggressive timeline, but finished the project several days early. We’ve never before worked with a contractor who made our goals their goals and our schedule their schedule in the way Principal Builders did. Their professionalism, quality work, and commitment to the project and Excel Academy as their client was incredibly refreshing. We will definitely hire them again.

In the summer of 2011, our school needed renovation and repair completed in time for the beginning of our school year. The work had to be completed on a very tight timeline. Principal Builders worked quickly and effectively on our behalf. They started on time, they had excellent workmanship, and they were responsive to our every need. We were very pleased with the results and would work with them again in a heartbeat!

I am THRILLED with the work that Joe and Tim did in my office. We have a staff of 22 people and we had a break room that could accommodate 6. I needed to have a new space for my employees and Joe and Tim came through. Principal Builders renovated our storage space for us into a state of the art staff lounge. Their attention to detail is exquisite and they came through on every aspect of the job. What I appreciated most was their patience and guidance throughout the process as I was indecisive about many aspects of what I wanted done. This was my first experience with contractors and renovations and it couldn’t have been smoother. I would recommend Principals Builders to anyone who needs renovations of improvements in the home or office. These guys are first rate and honest. I would be happy to speak with anyone interested in using them for a project.

We’ve dealt with a few different contractors on several different projects in our home, but we got the feeling that Joe and Tim understood our vision for this particular project more so than anyone we’ve dealt with previously. We were impressed with their professionalism as they never presented us with problems; only solutions. They provided us with daily progress reports and were very positive about executing our plan to the letter. We would recommend Principal Builders, and would use their services again.

We have had a few contractors do work in our home, but when it came time to remodel both our kitchen and basement we wanted to be very selective. We ended up choosing Principal Builders and that was the best decision we could have ever made concerning our home. They truly listened to our ideas and completed both projects on time and on budget. They always treated our space like it was their own. We appreciated their progress reports and attention to every detail. We would definitely recommend them to anyone.

We really appreciate the time and effort put in by Principal Builders. We love every second we spend on the Cape and now we love it even more as our home truly sparkles.

Alan Miller President Dauntless Property ManagementYarmouthport, MA

We were planning a complete kitchen remodel but decided to hold off. Principal Builders did everything they could to spruce up the space with a complete refinishing of our 50 year old birch cabinetry. They replaced the hardware and installed a new backsplash. The kitchen looks great and when we do a complete remodel they will be the first and only contractors we call.

C & P McKennaBillerica, MA

We are incredibly pleased with our basement remodel. It is now the nicest area of the home. Principal Builders design suggestions were excellent and they made use of every possible space. The quality of the work and their professionalism was great. We have little children around and neatness and courtesy were very important to us and that is just what we got.”

We were very satisfied with the new bath Principal Builders built for us. Your quote was right on and there was never an issue with add-ons. Your staff was great, they started and finished when they said they would and cleaned up every day. We look forward to working with you on our next project and will recommend you to our neighbors!

J & M AbramsPeabody, MA

Principal Builders were wonderful from start to finish. We still cannot believe how amazing our new kitchen and dining room look every time we walk in our front door. We feel like we are in a different house. They walked us through designs and options with clarity and patience. They made us feel completely comfortable with their skills and ability to manage our kitchen renovation. They communicated with us throughout the whole project. They brought in a very professional crew. They were extremely neat and understanding that we were still living in the house during the renovation. They completed the work ahead of time and on budget. None of those nightmare project overruns! And we now have a gorgeous new space to entertain and enjoy family time. Thank You, Principal Builders.

Joe & Tim were pros throughout the entire experience – from driving the approval process with permitting, helping us with an Appeal to the Board of Building Regulations, to even going to the meeting in Taunton in our place! These guys totally went above & beyond. Also, their workers Will and Dan (including subs – plumbing and electrical) were top notch. They worked fast, were very flexible with changes, and just generally pleasant, hard working and trustworthy. We are already thinking about our next project with these guys. After our last experience with a GC who went over budget and time (plus shoddy work), this was a refreshing change!
