About Kevin Monahan

Hi, I'm Kevin Monahan, the plumber behind Straight Plumbing & Heating. I've spent over 10 years in residential plumbing and heating, and I'm licensed and fully insured in Massachusetts.

I built this business on a simple idea: tell people the truth about what their home needs. That means an honest diagnosis, clear pricing before I start, and the repair, replacement, or installation that actually solves the problem — not the most expensive one on the list.

I handle toilets, faucets, sinks, showers and tubs, water heaters, boilers and heating systems, drain clogs, garbage disposals, gas lines, and sump pumps. Anything from a leaking valve to a full water heater swap.
