How Much Does Power Washing Cost?

You walk outside, look at your siding or driveway, and — yep — it’s seen better days. The winters in Massachusetts are rough, summers bring humidity, and before you know it, you’ve got a cocktail of dirt, mildew, moss, and stains. The fix? Power washing. But here’s the question most homeowners ask first — how much does power washing actually cost?

The short answer: usually a few hundred bucks. The long answer: well, it depends on your house, your surfaces, your location, and whether you’re doing it yourself or calling in the pros. Let’s dig in.

Average Power Washing Prices in Massachusetts

Now, this isn’t a one-price-fits-all type of service. Every house and every project is different. But after scanning what local companies charge and listening to homeowners from Walpole to Worcester, here’s what you can expect:

House Exterior

anywhere from $250 to $750 for a typical 1,500-2,000 square foot home. Smaller homes can be closer to $250-$350, while larger or three-story houses can break past $900.

Decks

$100-$200 for a small deck, $200-$350 for a medium-sized deck, and up to $500+ if it’s a big one with stairs and rails.

Driveways

$200-$700, depending on length, concrete vs. asphalt, and whether oil stains need extra treatment.

Per Square Foot

many pros in Massachusetts work around $0.15-$0.30 per square foot, or in some cases, $0.60-$0.70 when they factor in materials and tougher cleaning.

So if you’re budgeting, think a few hundred bucks, not thousands - unless you’ve got a very large property.

Factors Affecting Power Washing Cost

This is where it gets interesting. You might call three power washing companies and get quotes that are $200 apart. Why? Here are the big factors:

  • Size & Complexity: A one-story ranch with easy access is simple. A tall colonial in Newton with landscaping all around? More ladders, more time, more money.
  • Level of Grime: Light dirt is quick. Heavy moss, mildew, or years of buildup need special soaps, scrubbing, and repeat passes.
  • Hot vs. Cold Washing: True ‘power washing’ uses heated water, which can cost 10-20% more than basic cold-water pressure washing. Sometimes you need that heat to deal with grease or heavy mold.
  • Surface Type: Vinyl siding is straightforward. Old brick, cedar shingles, or delicate stone patios take extra care (translation: extra cost).
  • Location: Boston and nearby towns often run a little higher than Worcester, Springfield, or the Cape. Demand, overhead, and travel time all factor in.

Extra Services That Add to Cost

Sometimes a company’s base price looks great - but then you realize extras are separate. Watch for these:

  • Gutter Cleaning: often $100-$200 more.
  • Roof Washing: $300-$800, depending on size and moss issue.
  • Fence Washing: $150-$300, depending on length.
  • Special Detergents or Eco-friendly : A small surcharge, but worth it if you’ve got kids, pets, or a garden nearby.
Regular power washing helps extend the life of siding, decks, and driveways while boosting curb appeal and preventing costly repairs.

Is Power Washing Worth It?

Think about the Massachusetts weather - snow, road salt, humid summers, falling leaves clogging gutters. Surfaces take a beating. Power washing isn’t just about looks - it helps:

  • Extend the life of siding, decks, and driveways by removing damaging buildup.
  • Boost curb appeal if you’re selling (a clean exterior is basically free staging)
  • Prevent repairs - moss and mold hold moisture that can eat at wood or shingles over time.

Spending a few hundred bucks every couple of years? Cheaper than siding replacement or a new deck.

DIY or Hire a Pro?

Massachusetts homeowners are split on this. Renting a pressure washer for the weekend is tempting - it’s usually $50-$100/day at Home Depot or Lowe’s. If you buy one outright, expect to pay $200-$500 for a basic consumer model.

Here’s the catch: these machines aren’t always as powerful as pro gear, and it’s easy to cause damage if you don’t know what you're doing. Too much pressure and you can etch wood, chip paint, or force water behind siding. And ladders plus a pressure washer? Let’s just say not everyone’s comfortable with that combo.

Hiring a pro means:

  • Faster Work (they can do in hours what might take you a whole Saturday).
  • Safer for your property.
  • Often a better finish since they use professional soaps and equipment.

So yes - you’ll spend more, but many Massachusetts homeowners agree it’s ‘money decently spent’.

How to Choose a Power Washing Company in MA?

If you’re leaning pro, don’t just grab the first name on Google. A few things to ask:

  • Do they use soft washing techniques on delicate surfaces?
  • Are they insured? (Important if they’re climbing ladders around your property.)
  • Do they include detergents and rinsers in their base price?
  • Will they walk around with you afterward for inspection?

Get at least two or three quotes - you’ll quickly see the fair range for your project.

In a Nutshell

On average:

  • Houses:$250-$900
  • Decks$100-$500+
  • Driveways:$200-$700

Yes, there are exceptions, and yes, you can DIY it for less. But for most homeowners, hiring a pro means less risk, less hassle, and a sparkling clean property.

And here’s the kicker - what feels like ‘just cleaning’ is actually a maintenance investment. Done regularly, it keeps your property looking sharp, your surfaces lasting longer, and your weekends free.

So next time you catch yourself staring at green siding or a dingy deck, remember - it’s not just dirt, it’s dollars slowly slipping away. Power washing fixes that.
