Cornerstone
Trade Solutions
One call. Three trades. Plumbing, HVAC & Electrical — all under one roof. Serving Guelph & the Waterloo Region since 2009.
One Call. Three Trades. One Accountable Team.
Managing multiple contractors is frustrating and expensive. Cornerstone Trade Solutions brings licensed plumbers, HVAC technicians, and electricians together under a single company. That means coordinated scheduling, unified accountability, and a team that knows your home or property across all three systems.
Whether you need a furnace installed, a bathroom roughed-in, or an EV charger wired — we have the licensed tradespeople on staff, not subcontracted. One call reaches all three.

What Our Customers Say
"Called Cornerstone for a furnace issue in the middle of January. They had a tech at our door within a couple of hours. Fast, professional, and the price was exactly what they quoted. Highly recommend."
— Sarah M., Guelph
"We used Cornerstone for a full bathroom renovation — plumbing, electrical, and the new in-floor heating. Having one company coordinate everything made the project so much smoother. No finger-pointing between trades."
— Dave & Christine L., Kitchener
"Finally got our EV charger installed properly — permitted, inspected, done right. The electrician explained everything clearly and cleaned up perfectly. This is the kind of service that keeps you calling the same company."
— Michael T., Waterloo
