Quick answer
Professional house soft washing in Halifax, NS typically costs $249–$899 in 2026, with most two-storey homes landing around $399–$449. The exact price depends mainly on your home's size, with small bungalows at the low end and larger executive homes at the high end.
If those black streaks running down your siding have you searching "how much does house washing cost," you're not alone — Halifax's salt air and humidity feed algae and mildew on exterior siding faster than almost anywhere else in the country. Here's exactly what to budget for a professional soft wash in 2026, and what actually moves the price up or down.
Average House Soft Washing Cost in Halifax, NS (2026)
Pricing scales primarily with home size and number of storeys. Here's what that looks like for common Halifax home sizes:
| Home Size | Typical Cost |
|---|---|
| Small bungalow (<1,500 sq ft) | $299–$449 |
| Mid-size two-storey (1,500–2,500 sq ft) | $450–$699 |
| Executive home (2,500–4,000+ sq ft) | $700–$999 |
Most two-storey homes in the HRM land around $399–$449. Where you fall within your size bracket depends on how much algae, mildew, or oxidation has built up, and how accessible your home's exterior is.
What Affects the Cost of House Soft Washing?
- Home size and storeys. More square footage and height means more surface area and more time on site.
- Siding material and condition. Vinyl, wood, stucco, and brick each need slightly different chemistry and dwell time. Chalky, oxidized vinyl needs extra treatment (more below).
- Amount of buildup. A home that hasn't been washed in several years takes longer to bring back than one cleaned annually.
- Accessibility. Tight side-yard access, dense landscaping, or a home backing onto woods all add time to the job.
- Add-on services. Gutter brightening, deck cleaning, or roof washing are priced separately from the house wash itself.
What's Included in a Professional House Soft Wash
At WashCrafters, every house soft wash starts with a walk-around to check siding material and condition, then a pre-rinse to protect nearby landscaping. We apply a biodegradable, pet-safe cleaning solution, let it dwell to break down algae and oxidation at the root, then rinse at low pressure from the ground up — never a high-pressure wand aimed at your siding.
Chalky or oxidized vinyl may need an add-on treatment
Older or sun-faded vinyl siding can develop a chalky, oxidized surface that a standard soft wash alone won't fully restore. If we spot heavy oxidation once we're on site, we'll point it out and quote a separate specialty treatment to fully restore it — it's not automatically bundled into your house wash price, and we'll never add it without your sign-off first.
DIY vs. Professional House Washing: Cost Comparison
A pressure washer rental runs roughly $60–$100 for a weekend, which can look like an easy way to save a few hundred dollars. In practice, that math often doesn't hold up on vinyl siding:
- High-pressure water can force its way behind vinyl panels, trapping moisture that leads to mold growth you can't see or reach.
- Pressure strong enough to strip algae can also crack, warp, or blow panels clean off older or brittle siding.
- Many vinyl manufacturers explicitly warn against high-pressure cleaning in their care guidelines — doing it yourself (or hiring a pressure-only company) can put your warranty at risk.
- A two-storey home is a multi-hour, ladder-heavy DIY project versus a professional visit usually wrapped up in 1.5–3 hours.
For homes with real algae buildup, older vinyl, or anywhere near ladders and second-storey siding, the $249–$899 professional cost is the safer value once you weigh the risk of siding damage against the DIY savings. If you want the fuller breakdown of why low pressure matters for vinyl specifically, we cover it in our soft washing vs. pressure washing guide.
Is House Soft Washing Worth the Cost?
Yes, on both curb appeal and protection grounds. Those black streaks are gloeocapsa magma algae, which spreads and worsens the longer it's left, eventually staining porous siding materials permanently. Regular soft washing keeps it from taking hold, protects your siding investment, and matters for resale — a streaked, neglected exterior reads poorly to buyers even when the home underneath is in great shape.

Frequently Asked Questions
How much does it cost to soft wash a house in Halifax?
Most professional house soft washing in Halifax costs $249–$899, with most two-storey homes landing around $399–$449. The exact price depends on your home's size, siding material, and how much algae or oxidation has built up.
Is soft washing more expensive than pressure washing?
Pricing is usually similar or even lower for soft washing, since it's the correct method for vinyl and painted siding. What raises cost isn't the method — it's home size, storeys, and buildup. Using high pressure on siding isn't actually cheaper; it's just riskier.
How often should I get my house soft washed?
Once a year is typical for most Halifax homes. Properties close to trees, shaded north-facing walls, or homes near the harbour often see algae and mildew return faster and may benefit from washing every 8–10 months.
Does house soft washing remove black streaks and mold?
Yes. Those black streaks are typically gloeocapsa magma algae, and our biodegradable solution kills it at the root rather than just knocking it off the surface, so results last longer than a simple rinse.
What's included in the price of a house soft wash?
A full exterior soft wash of all sides of the home, pre-rinse and protection for landscaping, a biodegradable pet-safe cleaning solution, a final rinse, and a walk-around inspection. If we notice heavy oxidation on your siding during the wash, we'll flag it and quote a separate add-on treatment to fully restore it — that's priced separately from the base wash, not bundled in automatically.
