Client Testimonials


4/3/17, by Kevin in Northborough, MA

Allain Construction provided professional and customized service at our home from start to finish.  As communicated to us, the completion of our hardwood floors was quick from when we hired them to do the job until completion of the job.  The contractors arrived promptly each morning and were a pleasure to work with.  We are extremely happy with the finished product which looks fantastic in our home.  Thank you Allain Construction!

Allain Construction is excellent. Really fantastic.

We hired them in the fall to do a bunch of small jobs around the house, which when considered together turned into a semi-large job. The last of these was an actual large job, specifically, enlarging the usable space in our finished basement, and replacing our boiler and water heater with new, energy-efficient equipment. Peter was so easy to work with, presented us with all of our options, answered all of our questions (of which there were about a million), was very prompt in returning voice mails and/or emails, and never hesitated to meet with us in person if he thought that would be a more helpful way to communicate or answer our question.

Not only that, but the project ended up turning into a two-stage process, with "everything but the boiler and water heater" going first, and then "boiler and water heater" coming a few weeks after, because we were also dealing with securing energy efficiency financing and other stuff. Peter was very understanding about the paperwork that had to be filed, and with the scheduling; he was more than happy to break up the project and work with our schedule, and he was in touch frequently in the interim time, in case we had any questions or needed anything more from him. Ultimately, the job was done beautifully and we were very satisfied with the results.

Fast forward four months and we are searching for a company/contractor to update our first floor with hardwood floors... as coincidence would have it, we had someone at the house at the same time that Peter arrived at the house to follow up on something with the previous project and discuss an aspect of the flooring project that a flooring-only company would not have been able to do (since it was not actually "floors" work). Since he was there anyway, he ended up talking about our new project with us, and suggested a flooring product that we had never heard of but which sounded like it would suit our needs perfectly. Within a few days he was back, with samples, a cost proposal, etc., and we hired him a second time, to do the entire job. Bonus points for not having to coordinate two contractor schedules.

The floors (and a LOT of other small things that went along with them) were done mostly while we were away on vacation, which was fantastic. We came back and it was like a new house! On the days that they were working while we were still home, Peter's team always put furniture back and packed their things away so that our lives were as un-disrupted as possible. They left the house clean (as much as is possible with the sawdust), they followed up with all of my questions (of which there were, once again, about a million), they took care of all the details that we didn't even think of when we set the job up or conceived of it in the beginning. Peter was in regular communication with us to make sure everything was going the way we wanted, explained everything that his team was doing and anything they might need to continue.

The job came out great, and we get tons of compliments on how it looks. I am very happy with it, and next time we have a project that's too big for us we will probably just call Peter first and skip the consultation process altogether.

We hired Peter Allain to remodel our kitchen, family room and deck and we could not be happier with the outcome!  Peter’s talented team of workers were always prompt, clean, courteous and provided a high attention to detail.

Peter is extremely reliable and responsive to all requests and questions. Just as important, the project was on time and on budget.

We would enthusiastically recommend Allain Construction for any home improvement project!

Peter and his team have helped us with several projects around our new home including installation of replacement windows, restoring proper structure of our porch, installing a new expanded closet in our master bedroom, and building a faux-chimney to enclose a central air conditioning duct. The craftsmanship is excellent and Peter and his crew are both amiable and responsive to our ideas and requests. Peter and his team are a pleasure to work with - we recommend Allain Construction for your home improvements!

Allain Construction is excellent - best contractor around. Had them turn a 1/2 bath into a full bath and it was an amazing job. We picked some tough material, like river stone for the shower base and a wall - difficult to work with, but it looks great. Then had them do the upstairs bath. We upgraded this bath to include a Bain air tub. We didn't like the look of a boring white skirt, so Allain Construction worked with us to design a beautiful tiled skirt.

We ended up having them do some additional work like - new interior doors, some wallboard and painting, etc. Everything came out great.  Lastly, I wanted to redo our patio - they put me in touch with a landscaper who is awesome and did a fantastic job.

We would like to take this opportunity to thank you and your crew for the terrific renovation project completed recently at our home in Wellesley. We are very pleased with the final results and have received numerous compliments from visitors to our home. The project went smoothly from beginning to end and we felt we were regularly kept informed of the progress and decisions that were necessary to be made. The skill and craftsmanship you, Russ, and Dave brought to the job was apparent from demolition to completion.
