Gas fireplaces need less attention than wood-burning units, but they still need attention. Pilot assemblies get dusty, burners drift out of adjustment, glass hazes over, and vent components accumulate lint or spider webs that quietly reduce output. Our annual gas fireplace maintenance service in St. Thomas restores every one of those systems to factory spec and hands you a fireplace that lights on the first try and burns like it did the day it was installed.

Why gas fireplace maintenance matters in St. Thomas

Reliable Ignition

A cleaned pilot assembly and freshly tested thermocouple means no clicking, no missed lights, and no frustration on the coldest night of the year.

Clean Combustion

Adjusted burners and clean logs produce a real flame pattern and prevent black soot streaks on the glass or masonry in St. Thomas.

Longer Unit Life

The number one thing homeowners can do to keep a gas fireplace running for 20+ years is book a proper service every year.

Our gas fireplace maintenance process

  1. 1

    Full Shutdown And Inspection

    We isolate the gas, open the unit, and inspect every internal component for wear, corrosion, or dust buildup.

  2. 2

    Pilot And Burner Service

    Pilot orifice, thermocouple, thermopile, and main burner all get cleaned or replaced as needed.

  3. 3

    Glass, Log, And Ember Cleaning

    Glass panes come out for proper cleaning, logs get re-positioned to manufacturer spec, and the ember bed is refreshed.

  4. 4

    Venting And Combustion Check

    Direct vent or B-vent components are inspected and cleared. We also verify pressure and CO output.

  5. 5

    Test And Sign-Off

    The unit runs through three full cycles before we hand it back to you. You get a stamped service report.

Common findings in St. Thomas

  • Pilot orifices clogged with dust or spider webs
  • Log positions drifted from spec — the number one cause of soot
  • Cracked glass gaskets letting combustion air in
  • Sluggish thermocouples on the edge of failure

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

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. - Brampton - 2026-05-27
Fixed a bad previous install
Another company left the vent termination too close to a window. Diamond re-routed it to code and documented the correction.
Stefan G. - Richmond Hill - 2026-03-16
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.
