Interlock driveway being pressure washed with a surface cleaner in Ottawa

Seasonal: April–October

Power Washing & Pressure Washing in Ottawa

Ottawa winters are hard on hard surfaces. By April, driveways and walkways are coated in grey road salt, interlock joints are full of grit and weeds, and the north side of the house has a green film of algae. Power washing strips all of that away in an afternoon and makes a tired property look years newer.

Why it matters

Professional Power Washing in Ottawa

AV Group uses the right pressure for each surface: rotary surface cleaners for even, stripe-free concrete and interlock, and low-pressure soft washing for siding, where high pressure would force water behind the panels. The result is a deep clean that protects your surfaces instead of damaging them.

What's included in our power washing service

Driveway power washing: asphalt and concrete, with oil stain pre-treatment
Interlock cleaning: joints flushed of salt, grit, moss, and weeds, with optional polymeric sand re-sanding
Deck and patio washing: wood, composite, stone, and pavers, ready for stain or sealer
Siding soft washing: vinyl, aluminum, stucco, and brick, using low pressure and biodegradable cleaners
Fence washing: wood, vinyl, and metal
Walkways, front steps, porches, and garage pads
Surrounding plants pre-wet and rinsed, with all debris cleaned up before we leave

Who it’s for

For Homes and Businesses

Residential

Homeowners getting ready for patio season, preparing to list a house, or restoring a deck before staining. Spring washing after the snow melts is the most common time to book.

Commercial

Plaza sidewalks, storefront entrances, restaurant patios, dumpster pads, and parking-garage entrances. We schedule early mornings or after hours so customers are never disrupted.

Local knowledge

Why Ottawa properties need power washing every spring

Ottawa uses a lot of road salt, and it doesn't stay on the road. Every car that pulls into your driveway drops salty slush that soaks into concrete and paver pores. As it dries and re-crystallizes, it flakes the surface (called spalling) and breaks down the sand between interlock pavers. Washing that residue out each spring is one of the cheapest ways to protect a driveway that cost thousands to install.

Shaded siding and decks in older neighbourhoods like Nepean, Alta Vista, and Manotick also develop algae and mildew from humid summers. Soft washing kills the growth at the root instead of just blasting the surface, so it stays clean longer. We work from late April, once overnight temperatures stay above freezing, through October.

FAQ

Power Washing Questions, Answered

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

The terms are used interchangeably in Ottawa. Technically, power washing uses heated water, while pressure washing uses cold water at high pressure. We choose the right pressure, temperature, and cleaner for each surface.

Will power washing damage my siding or interlock?

Not when it is done properly. We soft wash siding with low pressure and cleaners, and use rotary surface cleaners on interlock and concrete to avoid stripes or gouging. Joints are flushed gently so pavers stay in place.

Do you re-sand interlock after washing?

Yes. Washing removes old, salt-damaged joint sand. We can sweep in new polymeric sand once the surface is dry, which locks pavers in place and discourages weeds and ants.

When is the best time to power wash in Ottawa?

Late April to June is ideal for driveways and interlock (after the salt season). July and August suit siding and decks, and September–October is great for pre-winter cleaning.

Do I need to supply water or be home?

We connect to your outdoor tap. You don't need to be home as long as we have access to the tap and the area being cleaned.

Are your cleaning products safe for pets and gardens?

We use biodegradable cleaners and pre-wet and rinse surrounding plants. Keep pets inside until surfaces are dry.
