What Hamilton clients say
We had Jopie do a tenant fit out for our retail space in Hamilton. Biggest thing for us was staying open during construction, and they scheduled around our hours so we barely lost any business days. Communication was solid, got updates without having to chase anyone down.
We recently hired Jopie Construction Group to renovate our detached home, and they exceeded every expectation. The project included demolishing our old kitchen and three outdated bathrooms, installing a beautiful new kitchen, laying new bathroom tiles, installing a new bathtub, completing drywall repairs and mudding, and painting the entire home, including all walls and ceilings. The quality of their workmanship is outstanding. Every detail was completed with care, and they took the time to fix and touch up areas that needed attention instead of cutting corners. They were punctual, professional, respectful of our home, and kept us informed throughout the project.
Really happy with the results. We needed some structural and finishing work done, and Jopie Construction Group was meticulous about the details. Everything feels solid, precise, and looks fantastic. We will definitely be calling them again for future projects.
They are dependable, reliable, produce top notch work. I was not disappointed when I used them, use them you will not regret.

A company that is new to Ontario, and a founder who is not new to construction
Johnpaul Guminkiriza founded Jopie Engineering Group in Kampala, Uganda in 2016 and has been a project manager on developments including NSSF Solana Lifestyle Residences (approximately US$400 million) and Acacia Mall. After relocating to Canada he founded Jopie Construction Group to give Ontario homeowners and businesses the same schedule and budget discipline.
Read our storyQuestions to ask before you hire a contractor
How do I know if my contractor is properly insured in Ontario?
Ask for a certificate of liability insurance and a WSIB clearance certificate, and check that both are current before work starts. Contractors should provide both without hesitation. Fully insured and WSIB-covered. Documentation provided before work begins.
What happens if my project runs over budget?
Most overruns come from unclear scope and hidden conditions, not from the work itself. We give a written quote with inclusions, exclusions and allowances. If something unexpected turns up, such as old wiring or rot, we explain it and price it before proceeding, and nothing is added without your written approval. In older homes we recommend a contingency.
Do you handle permits and inspections?
Yes. When work needs a permit, such as structural changes, plumbing relocation, egress windows or secondary suites, we prepare and submit the application and book the inspections into the schedule. Cosmetic work like painting or flooring does not need one.
How soon can you start?
Most projects start after a walkthrough and a signed written quote. Timing depends on our current schedule and on material lead times — custom cabinets and specialty tile can add weeks. We give you a start window with the quote, and smaller jobs such as painting can often be scheduled sooner than large renovations.
What does your one-year workmanship warranty cover?
It covers defects in our labour and workmanship for one year after completion — for example a failed joint, poor finish or installation error — and we return to fix them. Materials are covered by the manufacturer's warranty, not ours, and normal wear, misuse and damage caused by others are not covered.
