What London homeowners say

Gas line run cleanly
Long run from the meter through a finished basement and you can barely tell where it goes. Careful work.

Brett T. · 2026-04-11

Annual service, no upsell
Serviced the unit, replaced a gasket, and told me the blower had years left rather than selling me one.

Yasmin H. · 2026-02-02

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

Insert transformed the living room
Open masonry fireplace was a heat vacuum. The insert has cut our furnace runtime noticeably and the fire is far nicer to look at.
