Hampstead NH Plumbing & Heating
Hampstead is home ground. JP Karos started out of East Hampstead on Webber Road, and a good share of the early customer base is still here: lake houses around Sunset Lake and Angle Pond, older capes along the Route 111 corridor, and newer construction filling in between. The lake properties carry the familiar converted-camp issues, and the older stock is mostly on oil or propane with boilers reaching the age where the repair-versus-replace conversation gets serious. This is the town where people are most likely to have watched our trucks for years, and that is a standard worth holding.
Our first customers are here. That is not a marketing line, it is why a Hampstead call gets taken seriously.

FAQ
Are you still based in Hampstead?
The original shop is on Webber Road in East Hampstead and it is where the business started. We are relocating operations toward the Portsmouth area to serve the whole seacoast better, and Hampstead stays a covered town rather than a dropped one.
What does a boiler replacement cost around Hampstead?
Expect somewhere between $8,800 and $23,400 installed for a gas or propane unit, driven mostly by capacity, zone count, and the state of the existing near-boiler piping. The estimate engine gives you a real range in about ninety seconds, and the site visit confirms the number before you commit.
Do you service the lake properties at Sunset Lake and Angle Pond?
Yes, and they have their own pattern: seasonal-to-year-round conversions, crawl-space plumbing that freezes, and heating sized for shoulder season rather than deep winter. We look at the whole picture instead of just swapping the box that failed.
