J. Davis Plumbing and Heating is the call for practical plumbing work around Weymouth, especially water-heater installations, leak repairs, and fixture-related jobs. Customers describe a plumber who steps into difficult situations, explains the work, and leaves the area clean. Angi lists the business as veteran-owned, with 16 years of experience and water-heater services; that profile also lists a Massachusetts trade-license number as a directory claim. The recent written reviews are uniformly positive. Homeowners describe relocating a tankless water heater, repiping a bathroom during a remodel, repairing a ceiling leak on a Saturday, and handling kitchen-sink leaks and bathroom clogs. Speed and follow-through recur: reviewers mention same-day completion, quick response, efficient work, fair or honest pricing, and no pressure for extra work. Angi adds five water-heater reviews from November 2025, including a replacement of a leaking unit and praise for a clean installation. The strongest fit is a homeowner who needs plumbing repairs or water-heater work and values quick scheduling and tidy execution. Before booking, confirm the exact scope and price for the job, and treat the trade-license number shown on Angi as a self-reported listing detail rather than independent verification. For a water-heater replacement, leak, or everyday plumbing repair, the customer accounts give a consistent reason to call. Ask about availability, materials, and the written estimate before work begins.

Great job relocating the tankless water heater. Clean work, efficient setup, and everything runs perfectly. Highly recommend.
My original contractor bailed in the middle of a bathroom remodel, and he stepped in and saved the day. Repiped the bathroom perfectly for the new fixtures, replaced the water heater, and found a restroom leak. You can tell he knows what he’s doing—our bathroom looks awesome!
Reliable, does great work and complete in a timely manner. I highly recommend
Very Professional. Called on a Saturday, for a leak in my ceiling, came right out and fixed it. Guy is a lifesaver!
Justin was great to work with and very responsive. To date, I've contacted Justin for a number of issues I was having with a leak in my kitchen sink and a clog in my bathroom. He works quickly and efficiently. He has fair pricing and I would definitely recommend him to others.
