Cornerstone Trade Solutions
Plumbing, HVAC & Electrical Services in Guelph
One call. Three trades — 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.

Mechanical Contractors in Guelph for Connected Trade Work
Many home and property projects are not only plumbing, HVAC, or electrical. A water heater can involve plumbing, gas, venting, water treatment, electrical clearances, and future service access. A heat pump can affect ductwork, panel capacity, controls, drainage, and comfort in older Guelph homes. A basement renovation can bring drains, waterproofing, heating, ventilation, lighting, and inspection requirements into the same plan.
Cornerstone is built for that overlap. Instead of asking a homeowner, builder, or property manager to coordinate separate contractors, our in-house trades look at the full mechanical system and plan the work together.

"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
