# Johnstone Plumbing & Heating Inc **Trade:** Plumbing · **Address:** 26 Glenwood Rd, Billerica, MA 01821 · **Phone:** (978) 729-9231 · **Languages:** English **Rating: 3.8/5** (medium confidence) — from 13 reviews across 3 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 0 reviews, 0 negative. ## The honest read Johnstone Plumbing & Heating is the Billerica call for practical plumbing and heating work, from water-heater replacements to boiler installations and household repairs. The company operates from 26 Glenwood Rd, and its Massachusetts plumber license 4640-PL-C is registry-verified active under Johnstone Plumbing Inc. The written reviews, spanning 2022 through 2024, repeatedly describe clean, careful work and unusually direct communication. A 2024 homeowner contacted Dan on a Saturday after a leak-detector warning near a water heater; Dan responded Sunday and arranged the replacement. In 2023, reviewers described a thorough boiler installation completed in a couple of days, and a 2022 review says the company replaced a failed boiler and leaking shower valve after diagnosing the problems by phone. Heating work is a recurring theme, but this is not only a boiler shop. Reviewers also mention water heaters, bathroom renovation estimates, plumbing repairs, and work across multiple properties. A realtor said Dan's work was neat and organized and that clients had good things to say; another customer described fair pricing and quick, clean work. The main limitation is recency: the 13 written reviews run through 2024 rather than the last six months, and the page shows 14 Google ratings overall. Before booking, confirm the current schedule, the exact scope of a larger bathroom or heating project, and the estimate details. The reviews describe prompt communication, but they do not establish a current 24/7 availability policy. Johnstone looks best suited to homeowners who want one plumber for both everyday repairs and heating-system work, with a documented history of tidy installations. Confirm the work plan and price in writing, then verify that the active license holder matches the contracting entity on the proposal. **Strengths:** - Responsive communication — reviewers describe prompt replies and clear updates - Clean installations — boiler and plumbing work is repeatedly described as neat - Heating expertise — reviewers cite boiler and heating-system installations - Fair pricing — a reviewer specifically calls the cost fair ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Massachusetts plumber license 4640-PL-C is registry-verified active under Johnstone Plumbing Inc. _(confidence: high)_ - [State License Registry](https://occupationallicensingandpermitting.mass.gov/madol/s/license-search-page) — “MA plumber license 4640-PL-C registry-verified active — registry holder of record: Johnstone Plumbing Inc” - Google shows 5 stars from 14 ratings. _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=Johnstone%20Plumbing%20%26%20Heating%20Inc&query_place_id=ChIJ96ckikCj44kRpb5DAsHHG3E) — “Google: 5★ from 14 ratings” - Reviewers describe responsive communication, clean work, boiler installations, water-heater replacements, and household plumbing repairs. _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChdDSUhNMG9nS0VJQ0FnSURubjUtNC1nRRAB!2m1!1s0x0:0x711bc7c10243bea5!3m1!1s2@1:CIHM0ogKEICAgIDnn5-4-gE%7C%7C?hl=en) — “5★ I found Johnstone plumbing on Google because I wanted to support a local company .
