Modern kitchen remodel in Acton, MA by Thomas Buckborough & Associates, featuring white shaker cabinets, quartz countertops, and pendant lighting

What Our Clients Think

"We are very pleased with our new kitchen! Thomas created a plan that worked well for us, and gave the kitchen the updated and warm look we were looking for. We were very happy with the quality of the work and excellent communication throughout. On time and on budget. Lead carpenter (Jon) was a pleasure to have on the job every day, and did a great job in minimizing the impact on rest of our home. Subs were first rate. And when we couldn’t vent the exhaust fan out the roof, and there were issues with the long run to vent out the back of house, the TBA team persisted and went the extra mile to resolve the issue. Called in an HVAC Co. to make it right. Much appreciated for an unanticipated problem. Highly recommend TBA!"

What Our Clients Think

"We had a very good experience with TBA in the remodel of our kitchen.  I thought having a local designer and a locally available team was a real advantage.  It allowed them to quickly respond to scheduling opportunities and keep the project moving on time and on budget.  I also thought their on-the-ground team was very strong and that they were very good at communication throughout the project, with standard weekly updates.  Overall, we were very happy with both the process and result."

Custom kitchen remodel with blue cabinetry, marble countertops, and sleek stainless steel appliances in Boston, MA

What Our Clients Think

"We bought our house with one big flaw - a cramped, dark kitchen.  We had a vision for how to address this, but it was a tall order, including pulling a chimney out of our house.  Thomas and his team did a great job translating our loose dream into solid plans, and his company did a fine job turning that dream into reality, on time and budget!  I'd recommend his company to anyone looking for remodeling work!"

What Our Clients Think

"If there were a day to give Thomas Buckborough more than five stars, I would do so. We first met him in 1995 when he was newly in business and took on a kitchen renovation (with some side jobs) for us. Since then, we have worked with him on at least five other projects, and each one has been completely successful. He and his crew just finished gutting and updating a bathroom.
Thomas is a skilled designer who listens to our thoughts and then improves them. Every single one of his crew, through the years, has been competent and delightful. We had another bathroom renovation going on during the pandemic, and they managed that with care and attention to safety.
I could not recommend him more highly."

Kitchen & Bathroom Remodel

Warm-toned kitchen remodel in Acton, MA by Thomas Buckborough & Associates, featuring cherry wood cabinetry, quartz countertops, and a functional island

What Our Clients Think

"We have worked with Thomas Buckborough & Associates on several projects over the past eleven years. We have always found Thomas to make excellent design recommendations and to deliver exactly what we requested on time and on budget. Phone calls are returned promptly and questions are quickly answered. Recently Thomas and his team remodeled our kitchen. They always showed up as promised; completed tasks with a minimum of disruption; and came up with excellent solutions to all of the challenges that an older home provides (for example, walls being out of square or discovering hidden behind the wall prior electrical work that had not been done to code and needed to be brought up to current code). They did a beautiful job. Their attention to detail shines through. We couldn’t be happier."
