Deck Refinishing & Staining in Thornhill
UCO Construction Group refinishes and restores decks across Thornhill. Every project on this page is a real Thornhill job with before and after photos.
Nearly every Thornhill deck we have worked on had the same problem: a coating that peeled. Some were painted, some had a red or brown stain lifting in sheets, and a few had boards that had split or gone soft underneath.
We replace the damaged boards first, sand the whole deck back to bare wood and refinish it with a stain that soaks in and wears gradually. Most jobs take one to two days.

Questions and answers
How much does deck refinishing cost in Thornhill?
It depends on the size of the deck, the railings and stairs and how much old coating has to come off. We give you a written quote after seeing it.
Why did my deck stain peel?
Coatings that sit on top of the wood crack, let water in and lift. A stain that soaks into the wood has no surface layer to peel.
Can a painted deck be stained?
Yes, once the paint is sanded off completely.
Can you replace a few bad boards?
Yes. We replace them before sanding so they blend into the finished deck.
