I recently had Garage Doors of Boston help with my garage door issues, and I couldn't be happier with the service. They were prompt, professional, and really took the time to explain everything to me. The quality of their work is top-notch, and I appreciate how they made sure everything was functioning perfectly before leaving. Definitely recommend them if you're needing garage door help.

My 2022-2025 experience hasn't been particularly good or bad. The lines in the tax season, when I mainly used this office, could become quite long, and not all the counters were always open then. Interestingly, the first time I was sending my taxes, the clerk got somewhat irritated that I picked a Priority Mail envelope (mostly to fit everything nicely without folding) and thus paid more than I needed.

Not sure why all the bad reviews, but the girl who served me was extremely kind, helpful and a pocket of sunshine!

This place is a horrific sick joke.
They never have enough staff,
The staff are rude, disrespectful and inept.
Every single time it’s over a 30 minute wait in line, even if there’s one person in line.
I walked up to buy stamps and the clerk just said no
I said what do you mean no
Imagine on a holiday week they had two sheets of stamps at the front counter????? So I said fine you can process them through the machine, and the clerk refused told me to go to the self service machine
Waste your precious time doing something else like eating glass instead of coming here!
It would be hysterical if it wasn’t pathetic.
