The Pacific Northwest problem

Rain Doesn’t Clean
Your Windows. We Do.

Pacific Northwest weather creates a cycle that works against your home’s exterior — constant moisture, algae, moss, and hard water deposits build up season after season. Rain doesn’t wash it away. It bakes it in. Our professional wash removes years of buildup and restores the look your home had when it was new.

The Highest-ROI Thing You Can Do
Before Listing Is Wash Your Home.

Real estate agents consistently rank exterior cleaning as one of the best pre-listing investments a homeowner can make. First impressions drive offers — and curb appeal starts the moment a buyer pulls up. If you’re preparing to sell, refinance, or simply protect your investment, a professional exterior wash is the smartest place to start.

  • Clean exteriors photograph better — better photos mean more showings
  • Buyers perceive a clean home as a well-maintained home
  • Removes the objections buyers use to negotiate your price down
  • We work with homeowners exploring all selling options — traditional market or otherwise

“Our home looked like a new build after they finished. The windows were so clean I forgot we had a view. Genuinely couldn’t believe the difference — and they were done in half a day.”

“We were getting ready to list our house and our realtor told us to get the exterior cleaned first. North Coast did the windows, siding, and gutters in one visit. Our listing photos looked incredible.”

Common questions

FAQ

How much does window and siding washing cost?
Most residential window jobs run $150–$350. Full exterior siding wash typically runs $250–$600 depending on home size and condition. We always quote before starting — no surprises.
What’s the difference between soft wash and pressure wash?
Soft wash uses low pressure and biodegradable cleaning solution — safe for painted siding, wood, and delicate surfaces. Pressure wash uses high pressure and is best for concrete, driveways, and decking. We select the right method for each surface.
Do you clean interior windows too?
Yes. Interior window cleaning is available as an add-on to any exterior job. Just let us know when you book.
How often should I have my exterior washed?
In the Pacific Northwest, once a year is the minimum — twice a year (spring and fall) is ideal for properties with significant moss, algae, or tree coverage.
Is soft washing safe for my plants and landscaping?
Yes. We pre-wet all surrounding plants and landscaping before applying any cleaning solution, and rinse thoroughly afterward. We’ve never had a plant casualty.
