Built on Trust.
Proven by Results.
Pro Seel was founded by Berry Welsh with a simple belief: homeowners and businesses deserve honest, high-quality asphalt protection at a fair price. Over 25 years later, that commitment hasn't changed. What started as a one-truck operation in Hamilton has grown into the region's most trusted sealing company — completing more than 36,000 jobs across Hamilton, Oakville, Burlington, and Caledonia. We're still family-owned, still hands-on, and still obsessed with doing the job right the first time. No shortcuts, no upsells, no surprises.
