TLDR
Pressure washing a single surface in Montclair — a driveway or a deck — typically costs $120–$400. A whole-property package (house, driveway, walkways) runs $500–$900. Older wood siding, cedar shake, and asphalt roofs need soft washing, not high pressure, to avoid stripping paint or forcing water behind the surface.
How Much Does Pressure Washing Cost in Montclair, NJ?
Pressure washing a driveway or deck in Montclair costs $120–$400, and a full exterior package covering the house, driveway, and walkways runs $500–$900. The bigger question for Montclair's older housing stock usually isn't price — it's method. Wood siding, cedar shake, and asphalt shingle roofs need a gentler soft wash, not blasted with high pressure, or you risk paying for damage instead of a clean.
Pressure Washing Cost by Surface
Most companies price by surface and square footage, not a flat rate. Here's what Montclair homeowners typically pay per job:
| Surface | Typical Size | Cost |
|---|---|---|
| Driveway (1-car) | 400–600 sq ft | $120 – $220 |
| Driveway (2-car) | 600–900 sq ft | $180 – $320 |
| Walkways / paver patio | Varies | $150 – $300 |
| Wood deck (wash + brighten) | 300–500 sq ft | $200 – $400 |
| Composite deck (soft wash) | 300–500 sq ft | $150 – $300 |
| House siding — vinyl/aluminum | Whole exterior | $300 – $550 |
| House siding — wood/cedar shake | Whole exterior | $400 – $700 |
| Roof soft wash (algae/moss) | Whole roof | $350 – $650 |
| Whole-property package | House + driveway + walks | $500 – $900 |
Wood siding and cedar shake cost more than vinyl to wash — not because the job is bigger, but because it has to be done slower and at lower pressure to avoid damage, which adds labor time without adding square footage.

These are two different techniques, and the right one depends entirely on the surface:
Pressure washing (high PSI)
Uses 1,500–3,000+ PSI of water pressure alone to blast off dirt and stains. Good for concrete driveways, brick pavers, and stone — surfaces tough enough to take direct force.
Soft washing (low PSI + solution)
Uses low pressure combined with a biodegradable cleaning solution that kills algae, mold, and mildew at the root rather than just knocking off what's visible. This is the correct method for painted wood siding, cedar shake, stucco, and asphalt shingle roofs — anything that high pressure could strip, crack, or force water behind.
If a quote doesn't specify which method they're using on your siding or roof, ask. A company that treats every surface the same — full pressure, every time — is the one most likely to leave you with a repair bill.
Before You Paint or Sell: Why Timing Matters
Paint applied over dirt, chalking, or mildew residue fails early — often within two to three years instead of the seven to ten you'd expect from a quality job. If a repaint is on the calendar, our house painting cost guide covers pricing, but the sequence matters as much as the paint itself: wash first, let the surface dry fully (2–3 days minimum, longer in humid weather), then paint.
The same logic applies before a sale. A clean exterior is one of the cheapest ways to improve curb appeal photos and first impressions, and it also gives you an honest look at what's underneath — sometimes a wash reveals soft or rotted trim that a fresh coat of paint would have hidden until an inspector found it.
How Older Montclair Homes Change the Job
Montclair's tree-lined streets are part of what makes the town attractive, but they're also why algae and green staining show up faster here than in newer, more open subdivisions — shaded, north-facing walls stay damp longer after rain, which is exactly what algae needs. Homes on heavily wooded lots are the ones that most often need a wash more than once a year.
If your home is in one of Montclair's historic districts, that's a reason to be more careful about method, not less — original wood clapboard, shingle siding, and old mortar joints on brick foundations are more vulnerable to high pressure than modern materials, and damaging original material during a cleaning is the kind of mistake that's expensive to fix and hard to match. For siding condition questions beyond just dirt, our siding replacement cost guide covers when a wash won't be enough.
Older driveways and walkways — Belgian block, brick, or original poured concrete — also respond differently to pressure than modern asphalt. If your driveway project involves resealing afterward, see our driveway paving and sealing guide for how washing fits into that timeline.
How Often You Actually Need It
Once a year covers most Montclair homes — spring is the most common time, after winter grime and before outdoor entertaining season. Decks get an added benefit from a spring wash: it's also the right moment to check whether the wood needs re-staining, since our deck and patio cost guide covers what that refresh typically runs.
Skip the annual "just to be safe" wash if your siding and driveway still look clean — over-washing wastes money and, on some materials, accelerates wear. The signal to book is visible green or black staining, not the calendar.
How to Hire a Pressure Washing Pro in Montclair
- Confirm they use soft washing on painted wood, cedar shake, stucco, and roofing — not just high pressure on everything.
- Ask for proof of liability insurance. Cracked windows, stripped paint, and damaged trim are the most common claims in this trade.
- Get the PSI and method in writing for each surface being cleaned, especially on older homes.
- Ask what cleaning solution they use near plantings and lawn — some detergents damage landscaping if not rinsed properly.
- For a full exterior refresh, ask whether they bundle house, driveway, and walkway pricing — it's usually cheaper than booking separately.
Frequently Asked Questions
How much does pressure washing cost in Montclair, NJ?
A single-surface job — just the driveway or just the deck — typically runs $120–$400 depending on size and material. A whole-property package covering the driveway, walkways, and house exterior runs $500–$900. Roof soft washing for moss and algae is usually priced separately, at $350–$650.
What's the difference between pressure washing and soft washing?
Pressure washing uses high water pressure (1,500–3,000+ PSI) to blast away dirt and works well on concrete and masonry. Soft washing uses low pressure combined with a cleaning solution to kill algae, mold, and mildew at the root, and is the right method for painted wood siding, cedar shake, asphalt shingle roofs, and stucco — surfaces that high pressure can strip, crack, or drive water behind.
Will pressure washing damage the old wood siding on my Montclair house?
It can, and it's the single most common complaint homeowners have after hiring the wrong company. High-pressure water forced against old clapboard or cedar shake can strip paint, split wood, and push water behind the siding into the sheathing — leading to rot you won't see for a year or two. A soft wash at low pressure with the right cleaning solution handles algae and grime without that risk, and any pro who's worked on Montclair's older housing stock should default to it without being asked.
Should I pressure wash before or after painting my house?
Before, always, and with enough dry time between. Paint applied over dirt, mildew, or chalking residue fails early — often within two to three years instead of seven to ten. Plan the wash at least 2–3 dry days before a painting crew starts, longer in humid stretches, so the surface is fully dry before primer goes on.
How often should a Montclair home be pressure washed?
Once a year is standard for most homes. Properties shaded by mature trees — common on Montclair's older, tree-lined streets — often need it more like every 8–10 months, since less direct sun means algae and green staining come back faster on the north- and east-facing walls.
