The honest call

Soft wash or pressure, surface by surface?

The machine everyone rents is the wrong tool for most of the house. Here is which surface gets which treatment, and why it matters.

Siding

Soft wash. Always.

Method: Low pressure, cleaning solution does the work, thorough rinse
Why: High pressure drives water BEHIND siding and strips paint

If someone points a pressure tip at your siding, the algae comes back and the water damage stays. It’s the trade’s number-one amateur tell.

Roof

Never pressure. Ever.

Method: Soft wash treatment, moss and algae die off over weeks
Why: Pressure strips the granules that ARE the shingle’s lifespan

A roof that looks perfect an hour after “cleaning” was probably blasted. Treated moss lets go slowly, that’s the correct kind of slow.

Concrete & stone

Where pressure belongs.

Method: Surface cleaner for even coverage, pre- and post-treatment
Why: Wand-only jobs leave zebra stripes you’ll see for a year

Honest expectation: deep oil stains lighten dramatically, they don’t always vanish. Anyone promising 100% hasn’t met your driveway.

Wood & decks

Gentle, or forever fuzzy.

Method: Low pressure, right distance, with the grain
Why: Etched wood fibers never lie flat again

A blasted deck feels like felt and drinks twice the stain. Wood forgives dirt, it doesn’t forgive pressure.

One question sorts every company in this trade: “what pressure do you use on siding?” The right answer talks about the solution, not the machine.

Straight pricing

One number. In writing. It doesn’t move.

No hourly meter, no surprise line items, no “while we’re at it”. You approve one clear quote before a single nozzle opens, so you know the cost up front.

The exterior check

We visit, measure every surface and listen to what you actually want. Free, and it stays free.

Your clear quote

Every surface, its method and the haul-away, one line, one price. Approved by you before anything starts.

Signed & guaranteed

The number lands in writing with a 7-day re-wash promise. If a spot isn’t right, we come back and make it right.

The breakdown

What moves the number.

No mystery math. Four things decide what a wash job costs, and we walk every one with you before the quote lands.

Condition & prepPatching, sanding and priming take the time, wash takes the credit. Honest prep is most of the price.

Surface & heightSquare footage, ceiling height and how much furniture has to move.

Trim & detailCrisp lines around trim, windows and built-ins are hand work, and worth it.

TimingFlexible scheduling costs less. A hard deadline can be met, priced plainly.

Whatever the mix, you get one clear quote, in writing, before any work starts.

What a serious wash quote includes, ours or anyone’s:

Each surface listed, with the method per surface
What’s in the solution, and the plant-protection plan
Windows, seals and fixtures: how they’re protected
Water source: yours or theirs, stated
Honest stain talk: what lightens vs. what vanishes
Re-treatment terms if growth returns early

“We pressure wash everything” is not a method, it’s a warning. The method line per surface is what you’re paying for.

Recent jobs

Real work, in plain numbers.

Three jobs from the past few months, what they were, where, and how long they actually took.

House softwash, siding

Sellwood·1 day

Two-story cedar-lapped bungalow soft washed at low pressure with a sodium-hypochlorite mix to lift the north-side algae and mildew. Windows and plant beds rinsed down and pre-wet before and after so nothing got burned.

Roof moss removal

Laurelhurst·2 days

Heavy moss on a north-facing composition-shingle roof cleared by soft wash only, no pressure that would strip the granules. Gutters flushed after and zinc strips set along the ridge to slow regrowth.

Driveway spot restore

Montavilla·3 hours

Oil-stained concrete driveway degreased, then run with a surface cleaner for a stripe-free even finish. Rust marks near the gate pre-treated by hand before the final rinse.

Where we work

Proudly serving the Portland metro

A lot of our work comes from a neighbor who watched us wash the house next door. If you're in the metro, we're just around the corner.

Nine damp months grow algae on every north-facing wall in town — the green film isn’t dirt, it’s alive, which is why treatment beats blasting and fall is the smartest wash on the calendar.

How it goes

From first call to done.

No mystery in the middle. This is the path the job actually takes, start to finish.

The walkthroughday 1

We come out, walk the whole property with you, and test-wash a small hidden patch so you see exactly how the siding, roof or concrete reacts. You point out the stubborn spots, we note surface types, water access and anything fragile like light fixtures or plantings.

Quote lands in writingwithin 48 hours

You get a clear quote by email that lists every surface, the wash method for each (soft wash vs. surface cleaner) and what is and isn't included. No hourly guessing, no day-of surprises on the number.

We lock the date1-2 weeks out

Once you approve, we schedule around the weather since soft-wash chemicals need dry conditions to work right. You get a confirmed day and a heads-up the evening before so you can move cars and pull in patio furniture.

Job dayday of the job

The crew arrives in the morning, tarps or wets down plants first, and works top-down: roof and gutters, then siding, then flatwork. We stay on soft-wash pressure where the surface calls for it so nothing gets etched or stripped.

We walk it before we leavebefore we leave

We rinse down, pack up, and walk the finished property with you spot by spot until you're happy, re-hitting anything that needs it. You leave with the written soft-wash and moss-treatment warranty in hand and the site cleaner than we found it.

Before you hire anyone

Five questions for every wash company.

Including us. The equipment costs $300 at the hardware store, which is why this trade has more vans than professionals. Five questions find the pros.

01What pressure goes on my siding?

The right answer talks about soft wash and solution, not machine horsepower. Pride in PSI is pride in the wrong number.

02How do you treat a roof?

Anything with the word “pressure” in it ends the call. Roofs get treated, not blasted, the moss dies over weeks, on purpose.

03What’s in the mix, and what about my plants?

A pro names the solution and the protection plan, pre-rinse, covers, post-rinse, before you ask twice.

04Are you insured for water damage?

Water in the wrong place is this trade’s whole risk. The certificate should arrive faster than the quote.

05Will my driveway have stripes?

Ask if they use a surface cleaner on flatwork. Wand-only concrete jobs autograph themselves for a year.

Bring this list to the call. We’ll answer all five before you ask.

Good to know

Questions, answered

Getting started

Do you charge for estimates?+

No. Written estimates for houses, roofs, concrete and commercial exteriors are always free, we visit, measure, talk through surfaces and scope, and email you a clear, itemized quote with no obligation.

How soon can you start?+

Most estimates go out within a day, and typical projects are scheduled within one to two weeks. For urgent rewashes, before a move, a sale or an event, just tell us the date and we'll do our best to fit you in.

What does “free estimates” mean?+

Before any work begins, we give you one clear quote to approve, prep, materials and labor included. No hourly meter, no surprise add-ons at the end. You always decide before we start.

What should I do before you arrive?+

Close the windows, move cars off the driveway and leave the hose bib on, that is genuinely everything. Pets stay inside while solutions dwell.

How do you price a wash?+

Surfaces, square footage and buildup, one clear quote in writing after the free exterior check. Packages for house+roof+concrete save real money.

Can you give a price over the phone?+

A fair range from photos and your address on the map. The quote lands after eyes on the buildup, that check is free and quick.

What happens during the free exterior check?+

We walk the exterior, test a discreet patch, note delicate spots and pick the method per surface, ten minutes, then a flat quote with everything listed.

Are you insured for this work?+

Fully, liability and workers comp, certificates on request before we start. Ladders and water demand nothing less.

Soft wash & your surfaces

Will the solutions hurt my plants?+

No, because we pre-rinse beds, dilute correctly and rinse again after. Landscaping survives every wash or we have failed at the job.

Soft wash or pressure, who decides?+

The surface does. Siding and roofs get soft wash only, concrete gets a surface cleaner, wood gets low fans. We test a patch at the free check and show you.

Is my roof safe to clean?+

Only without pressure, which is exactly how we do it. Treatment kills the moss, weather carries it off, granules stay where the manufacturer put them.

Which surfaces does my home need?+

Tap through the Surface Studio above, siding, roof, concrete, deck, and the page takes each tone. The free check turns it into one flat plan.

Results, weather & durability

How long do results last?+

Houses stay bright two to three years here, roofs longer once treated, concrete depends on trees and traffic. Prevention advice comes free with every job.

Do you work in rain?+

Light Portland drizzle, happily, it even helps rinsing. Storms and freezing days move the appointment, your surfaces do not care about our schedule.

When will I see the roof results?+

Streaks fade in days, moss browns within weeks and sheds with weather. Roofs are the slow, safe reveal, we tell you the timeline up front.

Do you offer maintenance plans?+

Yes, annual refresh plans hold the bright at a lower rate, most homes alternate house wash and roof treatment years.

Is the Care Plan worth it?+

For most homes, yes: an annual inspection, free scuff and touch-up visits, priority scheduling, and 15% off future projects typically pay for the membership the first time you use it, and keep every finish looking new.
