A homeowner writing in November 2025 said they had been working with this family since 1998 — first the father, and that week the son. William made an old wood floor shine again, they wrote, including rough patches that had sat under carpets soaked by older dogs. Alpha Floor Sanding has been around Boston a long time. The Better Business Bureau lists the business as started in 1984 and incorporated in 1987, run out of Hyde Park by president William Nguyen, and accredited with an A+ since 2010. The company's own site says it has been sanding Boston floors since 1984, describes itself as the first Vietnamese floor sander in Massachusetts, and lists sanding, staining, refinishing, installation and repairs for residential and commercial clients, along with an EPA Certified Renovator credential and a Boston Magazine Best of Boston mention. The customers who keep coming back are the strongest thing here. A March 2025 customer had Alpha install hardwood in their own house, their Cape house and their rental apartments over the years, and got what they called a reasonable price on a floor repair from the new owner. A March 2024 customer, on their second job, had a couple of rooms, two hallways and a set of stairs refinished, with more floors booked for the following month. In a May 2023 review, another said the crew came back over a weekend to finish a piece of floor that had been left out. Two reviews from July 2024 read very differently, and both concern dealing with the owner rather than the sanding. One reviewer, who says they have worked in construction as both a contractor and a homeowner, described repeated attempts to communicate with Quinn Nguyen and the worst treatment they had had from a contractor. The other wrote that the owner lied to them three times and could not be trusted. A March 2025 customer describes Quinn's son as the new owner, and the BBB lists William Nguyen as president. For sanding and refinishing old Boston floors, the repeat business speaks for the work itself. Settle in writing who your point of contact is, what the scope covers room by room, and the dates — and hold the job to that.
I worked with William last week. I've worked with his dad since 1998. They did a sensational job. They made an old wood floor look new. It really shines. They even got some rough areas to shine that had been under carpets soaked from older dogs. William is very easy to work with, accommodating to my schedule and needs, and most of all, they did a terrific job. In the past, they did a job for me to sand the hard wood until tiles that were removed. But the floor under the tiles needed to be replaced. They replaced the flooring right on the spot that day, and did a terrific job for incredible price. I am already planning to use Alpha Sanding again next year, when I m away. I know the job will be complete when I return and I would be surprised if I wasn't thrilled with their work.
We worked with Alpha and the previous owner (Quinn) many times in the past. They installed hardwood floors for our house, our Cape house and our rental apartments. The new owner, Quinn son was also extremely helpful, and gave me a reasonable price for a floor repair. They always showed up on time, and did quality work!
I would highly recommend them, they are fast, clean, very friendly and the quality of their work is exceptional.
William was very responsive and professional. They showed up when they said they would and completed the job on time. They were also very reasonably priced. Would highly recommend!
Do NOT use these guys. The owner lied to me 3 times! They can NOT be trusted!!
