What St. Thomas homeowners say

Honest advice on sizing

I wanted a bigger unit. They explained why it would overheat the room and recommended a smaller model — and were right.

Ravi S. · 2026-01-19

Electric unit in the condo

Building would not approve gas. They framed and installed a recessed electric linear unit in a day and it looks built-in, not bolted on.

Chloe V. · 2026-06-09

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.

Marcus B. · 2025-12-04

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.
