Our story

A Hamilton trades company built on one rule

Cornerstone Home Services started in 2007 with a single rule: write the estimate before you touch anything. Nearly two decades later we still run the same way, seven certified technicians, a fully stocked service fleet, and every job backed by a written quote your approve before we begin. We look after plumbing, HVAC, electrical, and general home repairs so Hamilton homeowners have one reliable company to call. Our clients bring us back year after year and refer their neighbours because they know the price they see is the bill they pay.

Customer reviews

What Hamilton homeowners say

Called on a Tuesday morning about a burst pipe under the sink. A technician was at my door by noon, showed me the problem, and had it fixed before dinner. No upsell, no surprises on the bill.

My furnace quit on the coldest day of the year. Cornerstone had a tech out the same afternoon, found a faulty igniter, and replaced it on the spot. The written estimate matched the invoice to the dollar.
Darnell Whitmore · Google
Excellent experience from start to finish. They patched three leaky faucets, replaced a corroded shut-off valve, and even noticed a small issue with our water heater that they fixed while they were there. Priced fairly and honest throughout.

Good to know

Common questions

Do you offer same-day or emergency service?
We do our best to offer same-day appointments for urgent issues like burst pipes or a heating system that has stopped working. Call us as early as possible and we will fit you in. Emergency after-hours calls are available for serious water or heating emergencies.
Are you licensed and insured?
Yes. All of our plumbers hold a valid Ontario plumbing licence, our electricians are ESA-licensed, and our HVAC technicians are TSSA-certified. We carry full liability insurance and WSIB coverage on every job.
How does your written estimate process work?
A technician diagnoses the problem first, then writes you a complete estimate: parts, labour, and timeline, before touching anything. You approve it or walk away at no charge. Nothing goes on your invoice that was not on that estimate.
What areas do you serve?
We serve Hamilton and the surrounding area including Ancaster, Dundas, Stoney Creek, Waterdown, and Burlington. Call us to confirm we can reach your address.
What does your warranty cover?
Every repair is backed by a 2-year parts and labour warranty. If anything we fixed fails within that period, we return and make it right at no charge to you.
