What St. Marys homeowners say

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.

Solid work, arrived late once

One late arrival due to traffic, but they called ahead. The installation quality itself was excellent and the flame calibration is perfect.

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.

Amanda P. · 2026-05-27

Linear insert install

Quoted in writing with every line itemised. Install took one day, the finishing is clean, and they registered the warranty for me.
