What is soft washing and why is it better than pressure washing for roofs?

Soft washing uses low pressure and biodegradable cleaning solutions to kill moss, algae, and lichen at the cellular level. Unlike pressure washing, it does not damage shingles, void warranties, or strip granules. Results last 12-24 months vs 3-6 months with pressure washing.

How much does roof moss removal cost in Portland Oregon?

Soft wash roof moss removal in Portland typically costs $650 to $1,350 depending on roof size and moss density. PDX Exterior Cleaning offers free quotes for all Portland metro area homes.

What is RO/DI water and why does it matter for window cleaning?

RO/DI stands for Reverse Osmosis / Deionization. It removes dissolved minerals from water, creating pure water that dries completely spotless on glass — no streaks, no mineral deposits. Most window cleaners use tap water which leaves residue. Our pure water system delivers a better result that lasts longer.

How often should I have my windows cleaned in Portland?

Portland's rain, pollen, and tree debris means most homes benefit from window cleaning 2-3 times per year — spring, summer, and fall. Our biannual and triannual maintenance plans offer significant savings over one-time pricing and include priority scheduling.

The math every Portland homeowner needs to see

Moss is quietly destroying
a $20,000 asset.

Portland's tree canopy creates year-round moss conditions. Left untreated, moss rhizoids physically lift granules off shingles, trap moisture, and accelerate aging — stripping 8–12 years from a roof that should last 25. One full replacement runs $15,000–$25,000.

Why our window cleaning is different

Pure Water.
Zero Streaks.

Most window cleaners use tap water and a squeegee — and leave behind mineral deposits that attract grime within days. We use onboard RO/DI filtration to produce near-zero TDS pure water. It clings to dirt, lifts it off the glass, and dries completely spot-free. No streaks. No residue. No revisits.

How We Work

The PDX Exterior Cleaning Signature Method

Most exterior cleaners spray and leave. We follow a proven 6-step process that protects your home, delivers lasting results, and treats your property with the care it deserves.

Property Assessment & Protection

Before we touch anything, we walk your property and identify every surface — siding material, window type, roof age, landscaping near work zones. We cover or pre-wet plants and bushes that will be near our cleaning solutions. Your property is protected before a single drop of water hits it.

🛡️ Fully Insured on Every Job

Soft Wash Pre-Treatment

For roofs, siding, and organic growth (moss, algae, lichen), we apply our low-pressure soft wash solution — a biodegradable, EPA-compliant mix that kills biological growth at the root. This isn't a temporary blast; it's a treatment that prevents regrowth for months longer than pressure washing alone.

🌿 Soft Wash — Safe for All Surfaces

Pure Water Window Cleaning

Our onboard RO/DI (Reverse Osmosis / Deionization) system filters your tap water to near-zero dissolved solids. This pure water naturally pulls dirt from glass and dries completely spotless — no squeegee streaks, no mineral deposits, no chemicals. We reach 1, 2, and 3-story windows safely from the ground using water-fed poles.

⚗️ RO/DI Pure Water Technology

Targeted Pressure Washing

Hard surfaces like concrete driveways, brick walkways, and wood decks get targeted pressure washing calibrated to the surface material. We don't use one setting for everything — concrete gets aggressive cleaning while wood surfaces get precise lower-pressure treatment to avoid fiber damage.

💧 Surface-Specific Pressure Calibration

Detail & Rinse

After the main cleaning, we detail tracks, sills, screen frames, and gutters edges. Every surface gets a final rinse to clear any residual cleaning solution. We also flush downspouts to confirm drainage is clear. The details are what separate a great job from a good one.

✔ Detail-Cleaned, Not Just Sprayed

Walk-Through & Sign-Off

We walk the entire property with you before we leave. We point out anything we noticed — potential gutter issues, roof areas needing attention, caulking that may need resealing. You only sign off when you're 100% satisfied. If anything isn't right, we fix it on the spot, no questions asked.

The honest reason plans exist: Portland has three real window-cleaning seasons — spring pollen (April–May), summer dust and wildfire smoke (July–September), and fall debris before the rains set in (October). Our triannual plan is built around exactly those three windows. Customers on a plan never have to remember to call — we reach out to schedule each visit. And hard water mineral deposits become permanent after 2–3 years of buildup, so regular cleaning protects your glass long-term.

All plans include our 100% satisfaction guarantee. Not happy after any visit — we come back free of charge.

🔒

Simple, secure plan billing

We keep a card on file and charge automatically 24 hours before each scheduled visit — so there's nothing to remember and no invoices to chase. You'll always get a reminder text before any charge. Cancel anytime with a single text to Enrique.

Common Questions

Answers From Enrique Directly

Why soft wash instead of pressure washing on my roof?

Pressure washing strips granules off shingles, voids most manufacturer warranties, and only removes the surface layer of moss — it grows back in months. Soft washing kills moss, algae, and lichen at the cellular level using low pressure and biodegradable solution. Results last 12–24 months and your roof stays fully intact.

How much does roof moss removal cost in Portland?

Our soft wash roof treatment runs $650–$1,350 depending on roof size and moss density. Most Portland two-story homes fall in the $850–$1,100 range. Every quote is free — call or fill out the form and we'll give you an exact number after a quick property assessment.

Are you licensed and insured?

Yes — fully licensed and insured on every single job. We carry general liability insurance so your property is completely protected. Never hire an exterior cleaner without verifying this — uninsured contractors leave you exposed if anything goes wrong.

What is RO/DI water and why does it matter?

RO/DI stands for Reverse Osmosis / Deionization. It strips all dissolved minerals from water, producing pure water that pulls dirt off glass and dries completely spotless — no squeegee marks, no mineral deposits, no streaks. Most window cleaners use tap water which leaves residue. Our system delivers results that last longer and look better.

Do you serve Lake Oswego, West Linn, Beaverton and Tigard?

Yes — those are four of our most active service areas. We also serve all Portland neighborhoods, Hillsboro, Gresham, Tualatin, Happy Valley, Milwaukie, Oregon City, and Vancouver WA. If you're in the Portland metro, we almost certainly cover you.
