Deck Cleaning & Staining in Ajax, ON

Strip the grey. Seal the wood.

Deck staining comes up on a lot of our Ajax calls, usually once the wood has gone grey and rain soaks in instead of beading. Our deck cleaning & staining in Ajax starts with a wash to lift dirt and mildew, then sanding once the boards are dry, then one or two coats of stain laid on without lap marks. On a standard 10x12 deck, cleaning plus staining usually runs $400 to $800.

Bringing Grey Ajax Decks Back to Colour

Ajax decks tend to be compact, because the lots are. A smaller deck is a quicker job, but it also takes concentrated wear: the same path from the patio door to the barbecue gets walked every day, and that's where the stain wears through first. Once bare wood shows there, water gets in, and the boards start to cup and check along the grain. A quick look at that worn path tells us whether a maintenance coat will do or the whole deck needs stripping.

The right stain depends on the deck. Semi-transparent stain shows the grain and is what we usually suggest for Ontario weather on a deck in decent shape. An older deck with replacement boards from past repairs often looks better in a solid stain, which evens out the patchwork. If the fence beside it is already stained, we can pick a tone that sits well with it so the yard looks like one piece.

Townhouse complexes add one more step. If yours has a property manager or a board, ask whether there's a set stain colour before we start, because redoing a deck in the wrong shade means paying twice. If the finish is still holding and the deck only needs a clean this year, a power wash on its own starts at $150.

How deck cleaning & staining works

  1. Power wash

    First we clean the deck with a pressure washer to get rid of dirt, mildew, old stain residue and surface grime.

  2. Sand

    Once the deck has dried, we sand it to knock down raised grain and give the stain a smooth, even base.

  3. Apply stain or sealant

    One or two coats of deck stain go on, applied carefully so you don't end up with lap marks or patchy spots.

  4. Dry and inspect

    The deck needs 24 to 48 hours to cure. If needed, we come back for a final look.

Deck Cleaning & Staining in Ajax: FAQ

Do you offer deck cleaning & staining in Ajax?

Yes. Ajax is part of our Durham Region service area, and we work there from our base in Bowmanville. Call or text (289) 928-5689, or request a free estimate online.

Can you do deck staining at a rental we own in Ajax between tenants?

Yes, as long as the weather cooperates. The deck has to be clean and dry before stain goes on, and it should stay clear of foot traffic for 24 to 48 hours afterward, which is a lot easier with nobody living there. Send us the dates the unit will be empty and we'll watch the forecast for a dry stretch inside that window.

What happens to the plants and patio stones when you wash and stain a deck in a small Ajax yard?

We cover nearby plants, the bottom of the siding and the patio before we start, and we aim the wash away from the fence so the neighbour's side stays dry. Close to the house and fence, stain goes on by brush or pad, where a drip or overspray would show. Anything that does land on stone gets wiped up before it sets.
