What Dorchester homeowners say

Great from quote to handover
In-home measurement, written quote the next day, install two weeks later, and a walkthrough of the controls before they left.

Julia N. · 2025-09-18

Clear commissioning paperwork
Gas pressure, spillage test, CO reading — all recorded and handed over. No other quote even mentioned commissioning.

Colin M. · 2025-11-22

Good install, unit was back-ordered
The install itself was excellent. The unit took an extra two weeks from the supplier, which they kept me updated on throughout.

Lauren F. · 2025-10-30

Wood to gas conversion
Liner, gas line, and a sealed insert. The room is genuinely warm now instead of drafty. Permit and inspection handled without me lifting a finger.
