About us

15 years under GTA houses, roofs and chimneys

Diamond Home Services was built around a simple frustration: homeowners were paying three different contractors to look at three parts of one system, and nobody was looking at how those parts interact.

A furnace, a water heater and a fireplace can all vent through the same chimney. Change one and you change the draft on the others. Most companies are licensed for only one of those appliances, so the interaction never gets checked — and that is exactly where carbon monoxide problems come from.

We hold gas, HVAC and chimney certifications together on purpose. Our technicians can service the furnace, inspect the flue it vents into and check the fireplace on the same shared chimney, in one visit, with one set of readings recorded against your address.

We also refuse to quote before diagnosing. The industry norm of a phone-quote followed by an on-site upsell is the single biggest reason homeowners distrust this trade. You get a written, itemised price after we have measured something, and nothing gets replaced without your approval.

Every visit ends with a written safety report in plain language: what we measured, what we changed, what is fine, and what will need attention in the next season or two. It is yours to keep, and it is what you hand the next technician or the next buyer of your home.
