# Woelfel Plumbing & Heating **Trade:** Plumbing · **Address:** 432 MA-28, Harwich Port, MA 02646 · **Phone:** (508) 432-8100 · **Languages:** English **Rating: 4.1/5** (low confidence) — from 3 reviews across 4 sources. ## The honest read Woelfel Plumbing & Heating is a family-run plumbing business based in Harwich Port on Cape Cod, working under a Massachusetts-licensed plumber, Derek Woelfel, whose registry license is active and verified. A related entity, Woelfel & Sons Inc., reports being in business since 2003, and a longtime customer describes Derek and his father having serviced their house for decades, pointing to a father-and-son operation with deep roots in the area. Customers who have hired them consistently point to responsive service and fair pricing, and one homeowner singled out a new hot water heater installation as excellent work delivered with professionalism and value. Business listings show a broader plumbing practice that includes gas piping, sewer line work, and fire sprinkler systems, alongside water heater and boiler work. Independent reviews are few, a small handful of five-star ratings on Google and BuildZoom with nothing negative found, and the Better Business Bureau lists the related business as Not Rated, saying only that it doesn't have enough information to issue one. What's publicly known here is thinner than the praise it contains, so it's worth confirming current availability and getting a written estimate before booking. Woelfel looks like a good call for straightforward residential plumbing and water heater work on the Cape from a small, established family shop, just go in with a specific scope and confirm pricing directly, since the reviews on file don't yet cover larger or more complex jobs. **Strengths:** - Water heater installation — customer praised a new install as excellent quality and value - Long-time family plumbers — one reviewer says served their house for decades - Responsive and fairly priced — reviewer highlights promptness and reasonable rates - Registry-verified license — active Massachusetts plumbing license on file **Concerns:** - Thin review base — only a handful of ratings recorded across platforms - No BBB rating — bureau lists the related business as Not Rated **Where sources disagree:** - BBB lists the related entity Woelfel & Sons Inc. with owner Francis Woelfel, while the registry-verified license and BuildZoom profile belong to Derek Woelfel; a Google review referencing 'Derek and his Father' suggests one family plumbing operation, but the two names have not been independently reconciled beyond that review. - BuildZoom's directory data lists a second license number (#20118) as 'Active' despite showing a 2018 expiration date; only the registry-verified license (#10383) is treated as current here. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Holds an active Massachusetts plumbing license (registry-verified), held by Derek Woelfel. _(confidence: high)_ - [State License Registry](https://occupationallicensingandpermitting.mass.gov/madol/s/license-search-page) — “MA plumber license 10383-PL-M registry-verified active — registry holder of record: Derek Woelfel” - A related family entity, Woelfel & Sons Inc., reports operating since 2003. _(confidence: medium)_ - [Better Business Bureau](https://www.bbb.org/us/ma/harwich-port/profile/plumber/woelfel-sons-inc-0021-436157) — “BBB profile for Woelfel & Sons Inc (432 Route 28, Harwich Port, MA), not BBB accredited, BBB rating Not Rated (insufficient information), 23…” - Google shows a 5-star average from 4 ratings. _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=Woelfel%20Plumbing%20%26%20Heating&query_place_id=ChIJby0UT0M--4kRiExaIpgArKg) — “Google: 5★ from 4 ratings” - BuildZoom shows a 5.0-star average from 1 rating. _(confidence: high)_ - [BuildZoom](https://www.buildzoom.com/contractor/derek-j-woelfel) — “BuildZoom: 5.0★ from 1 ratings” - A customer praised a new hot water heater installation as excellent, professional work with good value. _(confidence: high)_ - [BuildZoom](https://www.buildzoom.com/contractor/derek-j-woelfel) — “5★ New hot water heater.
