Basement Floor Coating in Markham
Finish your basement floor properly — sealed, decorative, and ready for everyday use.
Basement Floor Coating in Markham — what to know
The Decor Coatings crew installs basement floor coating for homeowners and businesses in Markham. Finish your basement floor properly — sealed, decorative, and ready for everyday use. Markham homes trend toward high-spec finishes and larger-than-average garages and basements — making it one of our most frequent sources of garage epoxy, basement coating, and decorative concrete feature requests.
Markham sits in the York region, and our scheduling runs same-day for consults. Local building eras range from mid-century bungalows to modern custom builds, which is why our quoting process always starts with an in-person slab inspection. For basement coating specifically, that means comprehensive moisture testing before quote, moisture-tolerant primer when vapour emission is high, matched to the actual condition of your slab or wall.
Our quotes include a written specification: what system, what thickness, what cure time, what warranty. Most residential jobs are booked within two weeks of quote acceptance.

Common questions
What if my basement had moisture problems before?+
We moisture-test first, always. If vapour emission is high, we spec a system that tolerates it. If there's active water intrusion, we'll flag that and recommend addressing the water source before coating.
Can I put furniture back right away?+
Light furniture after 48 hours. Heavier items (sofas, treadmills, dressers) after 5 days to let the floor fully harden under load.
Do you serve all of Markham?+
Yes — we work across every neighbourhood in Markham, including Unionville, Thornhill, Cornell, and surrounding areas. Scheduling is same-day for consults.
How does Markham's climate affect basement coating?+
The GTA's humidity swings and winter heating cycle affect substrate moisture, which is why we moisture-test every slab before scheduling. Basement Coating systems are selected to handle the conditions we find — including the salt and freeze-thaw stress that garage floors see from November through April.
