If your siding has gone from beige to faintly green and your driveway looks like a chalkboard, you're not slacking. You just live in Chatham-Kent. Between farm dust, river humidity and a winter's worth of road salt, exteriors around here get dirty faster than almost anywhere else in Ontario. The good news is that most of it comes off in a single afternoon if you use the right pressure and the right chemistry.
This guide walks through what pressure washing actually costs locally, why soft washing matters more than horsepower, and when to book so you're not waiting three weeks in the middle of June.
What Pressure Washing Costs In Chatham-Kent
Pricing in a small market is more honest than pricing in a big city, because everybody talks. Here's the range we quote most often across Chatham, Wallaceburg, Blenheim and Tilbury:
- Single storey house wash: $300 to $500
- Two storey house wash: $450 to $750
- Standard two car driveway: $180 to $350
- Roof soft wash, average bungalow: $500 to $900
- Gutter cleaning: $150 to $300, depending on height and debris
- Exterior window cleaning: $6 to $12 per pane
Three things move those numbers. Square footage is the obvious one. Access is the sneaky one, because a house tight to a fence line or a walkout with steep grade takes longer and needs more gear. And time since the last cleaning matters, since ten years of algae takes more dwell time and more product than eighteen months of dust.

Why Local Siding Turns Green So Fast
That green film isn't dirt. It's algae, and it's alive. It needs moisture, shade and a food source, and Chatham-Kent hands it all three. Humidity rolls off the Thames River and Lake St. Clair, our tree canopy keeps north and east walls damp well into the afternoon, and airborne organics from surrounding farm fields settle on every horizontal surface during harvest.
This is why a rinse never lasts. If you knock algae off with water alone, the root structure stays in the pores of the siding and it recolonizes within weeks. The fix is a cleaning solution that kills the organism, then a gentle rinse. Same principle applies to roofs, fences and north facing brick.
A rinse cleans what you can see. A soft wash kills what you can't, which is why it lasts three or four times longer.
Soft Washing Versus Pressure Washing
People use the words interchangeably and shouldn't. Pressure washing is mechanical, using force to blast material off a surface. Soft washing is chemical, using a low pressure application to kill growth and then rinsing it away. Choosing wrong is how exteriors get wrecked.
Soft wash these surfaces
- Vinyl, aluminum and painted wood siding
- Asphalt shingles and metal roofing
- Stucco, EIFS and older brick
- Cedar fencing and composite decking
- Awnings, soffit and fascia
Pressure wash these surfaces
- Concrete driveways, walkways and patios
- Interlocking brick and stone pavers
- Foundation walls and garage floors
- Commercial dumpster pads and drive through lanes
Roofs deserve their own warning. Those black streaks are an algae that feeds on the limestone filler in asphalt shingles. Hitting them with a pressure washer strips granules, voids most shingle warranties and can take years off a roof. Shingle manufacturers and roofing associations recommend low pressure chemical cleaning, which is exactly what a proper roof cleaning service uses.
The Best Time Of Year To Book In Chatham-Kent
Our season effectively runs April through October, with two clear rushes. Spring is the bigger one, because everyone sees salt haze and pollen at the same time. Fall picks up again when leaves drop and people start thinking about gutters and holiday lighting.
- April: best availability, salt and winter grime removal, perfect for concrete.
- May and June: busiest weeks of the year, book two to three weeks ahead.
- July and August: ideal for roofs and decks, since surfaces dry fast.
- September and October: gutters, final window cleaning and holiday light installs.

Road Salt, Concrete And Spring Cleanup
Chatham-Kent crews spread a lot of salt, and they should. What that means for your property is chloride sitting in concrete pores through every freeze and thaw cycle. Water gets in, freezes, expands and starts pushing the surface apart. That's spalling, and once it starts you're looking at replacement rather than cleaning.
Washing concrete in spring isn't purely cosmetic. Getting chloride residue out before the summer heat bakes it in extends the life of the slab. If your driveway is newer, a penetrating sealer after cleaning is the cheapest insurance available. Municipal winter maintenance details are posted by the Municipality of Chatham-Kent, and it's worth knowing which routes near you get treated most heavily.
How To Hire A Pressure Washing Company In Chatham-Kent
Exterior cleaning has a low barrier to entry. A used trailer and a box store washer is all it takes to print business cards, which is why quality swings wildly. Five questions sort the pros from the rest:
- Can you send a certificate of insurance?
- Do you soft wash siding and roofs, or pressure wash everything?
- Is the quote written and itemized, or a number over the phone?
- How do you protect landscaping, and do you rinse at the end?
- What happens if I'm not happy with a section?
Look for local references too. Small business standing in the community is easy to verify through the Chatham-Kent Chamber of Commerce, and Ontario consumer protection basics are worth a skim on the Consumer Protection Ontario site before you hand over a deposit. For the record, we don't take deposits on residential work.
Renting A Washer Versus Hiring A Pro
A rental washer runs roughly $70 to $110 a day around here. Add fuel, a surface cleaner attachment and detergent and you're at $150 or more before you've cleaned anything. For a small patio or a set of steps, that math works fine and you should absolutely do it yourself.
Where it stops working is height and chemistry. Rental units come with a pressure wand and no soft wash capability, so people end up doing exactly the wrong thing to their siding. Add ladder work at roof height and the risk changes completely. Falls from ladders are one of the most common serious home maintenance injuries in Canada, and no clean gutter is worth a hospital visit.
The honest split is this: hard, low, small surfaces are great DIY projects. Anything above your head, anything with living growth on it, and anything you'd be upset to damage is worth a professional.
Frequently Asked Questions
How much does pressure washing cost in Chatham-Kent?
Expect $300 to $500 for a single storey house wash in Chatham-Kent, $450 to $750 for a two storey, and $180 to $350 for a standard driveway. Access, square footage and how long it's been since the last cleaning are the main variables, which is why we quote in writing rather than over a hunch.
Do you serve Wallaceburg, Blenheim, Tilbury and Ridgetown?
Yes. Those towns are part of our regular Chatham-Kent routes, along with Dresden and the rural roads in between. We also run scheduled trips into Windsor, Sarnia and St. Thomas.
Can pressure washing damage vinyl siding?
It can. High pressure at the wrong angle forces water behind siding and into wall cavities, and it can crack older brittle vinyl. That's why siding gets soft washed with low pressure and a cleaning solution instead.
How often should a house in Southwestern Ontario be washed?
Most homes here look best on an every 12 to 18 month cycle. Properties with heavy tree cover, north facing walls or lots near farm fields tend to need it annually because organic growth comes back faster.
Is soft washing safe for gardens and pets?
When it's done properly, yes. We pre-wet plants, use the lowest effective mix and rinse everything down at the end. Keep pets indoors during the wash and let surfaces dry before they're back out.
Do I need to be home for the appointment?
No. We need an outdoor water spigot and clear access around the house. Plenty of Chatham customers leave a gate code and come home to a finished job with photos already in their inbox.
