Why TriCity?
The Concrete Sealing Specialists of SW Ontario
Unsealed concrete is porous. It absorbs road salt, oil, water, and UV rays — all of which cause staining, cracking, spalling, and fading. Proper sealing stops that cycle and extends your concrete's life by years.

How It Works
Our 4-Step Sealing Process
Every project follows the same proven process — no shortcuts, no skipped steps, no surprises.
Free Site Assessment
We visit your property to inspect the concrete surfaces, assess their condition, measure the area, and identify any preparation needed. You'll receive a detailed written quote — no surprises.
Surface Preparation
We deep-clean the surface using professional equipment, removing dirt, oil stains, moss, and any previous failed sealer. Hairline cracks are addressed before sealing begins.
Premium Sealer Application
Using professional sprayers and rollers, we apply an even, streak-free coat of premium sealer. Every application is inspected in real time for full coverage and proper penetration.
Quality Inspection & Warranty
We walk through the finished work with you to ensure complete satisfaction. Your 5-year written warranty starts from this point — you're protected from day one.
Industry-Leading Protection
Backed by a 5-Year Written Warranty
We don't just seal your concrete — we stand behind it. If there's an issue with our workmanship or materials within 5years, we'll fix it. No questions.

“TriCity sealed our driveway last spring and it still looks brand new. Zero staining from our vehicles and it survived a brutal winter without a single crack. Absolutely worth it.”
James T. — London, ON
“The crew was on time, professional, and the stamped concrete on our backyard patio looks incredible now. The colour really popped after sealing. Highly recommend them!”
Karen M. — Woodstock, ON
“We had our walkway and front steps sealed. The whole job took about 3 hours and the results are stunning. Great communication throughout and the pricing was fair.”
Derek L. — Brantford, ON
“After years of oil stains on my driveway I finally got it professionally sealed. TriCity cleaned everything up and applied a gorgeous semi-gloss finish. No more embarrassing stains!”

Common Questions
Straight answers about concrete sealing — from process and timing to cost and warranty.
Concrete sealing is the process of applying a protective liquid coating to concrete surfaces. Without sealing, concrete is porous and absorbs water, oil, road salt, and other substances that cause staining, cracking, spalling, and fading. Sealing locks out these damaging elements, extends the life of your concrete by years, and keeps it looking like new.
