What will a fireplace install cost in Langstaff, Richmond Hill?
Five questions, real Langstaff, Richmond Hill pricing. You get an installed price band including venting, gas, finishing and permit — before anyone calls you.
Gas is still the right answer for most homes in Langstaff, Richmond Hill: real heat during an outage-prone winter, no wood to store, and instant control. We install direct-vent sealed-combustion units, run the gas line, handle the permit, and hand you a commissioning sheet with the actual gas pressure and CO readings recorded.
Direct-vent done properly
Termination clearances to windows, decks, and property lines in Langstaff, Richmond Hill are code-controlled and frequently ignored by cheap installers. We plan the termination before selecting the unit.
Gas line and pressure
An undersized line starves the appliance and shows as a lazy yellow flame. We size the run to the appliance's BTU rating and verify with a manometer at commissioning.
Safety documentation
Every install leaves with a commissioning sheet: inlet and manifold pressure, spillage test result, CO reading, and the technician's TSSA number.

What Richmond Hill customers say
4.9 out of 5 from 743 reviews across the GTA. A selection relevant to this service below.
Another company left the vent termination too close to a window. Diamond re-routed it to code and documented the correction.
Quoted in writing with every line itemised. Install took one day, the finishing is clean, and they registered the warranty for me.
One late arrival due to traffic, but they called ahead. The installation quality itself was excellent and the flame calibration is perfect.
In-home measurement, written quote the next day, install two weeks later, and a walkthrough of the controls before they left.
