How long does a deck cleaning and power washing take?

A standard 200–400 sq ft deck takes 1–2 hours for the cleaning and washing, plus 24–48 hours of drying time before you can seal or stain. We'll give you the exact drying window based on the forecast.

Can you wash and stain in the same visit?

No. The wood needs to dry fully, usually 24–48 hours, before a penetrating stain can absorb properly. We'll schedule the washing and staining as two visits, typically 2–3 days apart.

What's the difference between power washing and soft washing?

Power washing uses higher pressure (1,500–2,500 psi) to remove built-up grime, mildew, and loose wood fibres. Soft washing uses lower pressure with chemical cleaning, it's gentler but doesn't remove as much. We use power washing for most decks, then a brightener to finish.

Deck Cleaning & Power Washing in Winnipeg

Deck cleaning and power washing in Winnipeg runs $150–$400 for most residential decks, with the final price driven by deck size, surface condition, and how much prep the wood needs before sealing or staining. A standard 200–400 sq ft deck lands between $250–$350; small balconies start at $150; heavily weathered or larger decks push toward $400.

What's Included

A deck cleaning and power washing from Deck Staining Winnipeg isn't a quick spray-down. It's a thorough process:

Full deck inspection, we check for rot, loose boards, popped nails, and structural issues before we start.
Pre-treatment, we apply a mildewcide and wood cleaner to kill algae, moss, and mildew so the pressure wash actually lifts the grime instead of pushing it around.
Pressure washing at the correct PSI, we use 1,500–2,500 psi depending on the wood. Cedar gets a softer touch; pressure-treated pine gets more. We never use a zero-degree tip, which gouges the surface.
Brightening, we apply a neutral oxalate brightener to restore the wood's natural colour after washing.
Debris removal, we rake up the lifted wood fibres and haul them away.
Drying guidance, we tell you exactly how long to wait before sealing or staining (usually 24–48 hours, depending on weather).

Pricing Breakdown

Deck size	Typical price	What drives cost
Under 100 sq ft	$150–$200	Small balconies, single-level step-downs
200–400 sq ft	$250–$350	Standard residential decks in Winnipeg
Over 400 sq ft	$350–$400	Large multi-level decks, wrap-around exterior

What pushes the price higher:

Heavy grime or algae, if your deck hasn't been cleaned in 3+ years, we may need a second pass. Add $50–$100.
Access, ground-floor decks are fastest. Second-storey decks or tight side yards add setup time.
Repairs, if we find loose boards, rot, or popped nails during the wash, we'll quote those separately. Washing doesn't fix structural issues.

Honest pricing: if you're bundling a wash with our staining service, the cleaning cost is often discounted, we'll give you a combined quote.

The Process

1. Inspection & fixed quote, we walk the deck, measure the square footage, and give you a fixed price. No hourly billing, no surprises.

2. Pre-treatment, we spray a mildewcide and wood cleaner across the entire surface. It kills organic growth and opens the wood pores so the pressure wash works in one pass.

3. Power washing, we use a 15-degree fan tip at 1,500–2,500 psi, working with the grain of the boards. We keep the pressure even so we don't etch the cedar or create furrows. For composite decks, we drop the pressure to around 1,200 psi and use a wider tip to avoid scuffing.

4. Brightening & drying, we apply a brightener to restore the wood's natural colour. Then we leave the deck to dry and give you clear instructions on when to seal.

Why Choose Us

We're a deck-only crew. We don't paint houses or wallpaper rooms. Decks are all we do, every job on our calendar is a deck. That means our crew knows the exact pressure settings, nozzles, and chemicals for cedar, pressure-treated pine, and composite. We're not general painters who do the odd deck; we're the specialists.

We know Winnipeg's climate. Freeze-thaw winters, gumbo clay, UV summer, your deck fights all of it every year. We clean and seal for the specific conditions of this city, not a generic national standard.

We use premium penetrating stains. We use Sikkens and TWP penetrating stains that flex with the wood as it contracts and expands through the seasons. No film-forming paint that peels by spring.

Full prep, not just a coat of paint. We sand, brighten, repair, and seal. You're paying for a deck that survives the next Manitoba winter, not a quick wash-and-paint.
