Reviews

What people say.

311 reviews across MetroWest.

  • Called at 11pm with water coming through the ceiling. Dave picked up, gave me a price, truck was there in 40 minutes.

    Rob D. Hudson June 2026
  • Flat rate, no surprises. The number he said on the phone was the number on the invoice.

    Priya S. Marlborough May 2026
  • Cleared a main line another company wanted $1,200 to dig up. Mercer jetted it for a few hundred.

    Mike T. Northborough May 2026
  • Old water heater died on a Sunday. New one in by the afternoon. Honest crew, clean work.

FAQ

Questions people ask.

Do you really answer 24/7?

Yes. A live person, not an answering service — nights, weekends, and holidays.

Is the price really flat?

Yes. We quote the whole job before we start. The number we say is the number you pay.

Why do you quote before you start?

Dave spent twelve years quoting jobs he wasn't allowed to price honestly. That's why this company exists. You get the price up front, every time.

How fast can you get here?

Most days, same day. For emergencies, usually within the hour across MetroWest.

Do you charge a trip fee?

Only on emergency dispatch ($250), and it comes off the repair if you go ahead.

Are you licensed and insured?

MA Master Plumber, fully insured. The license number is on every invoice.

Water won't wait. Neither do we.
