Pro­fes­sion­al Exte­ri­or Sur­face Clean­ing in Seattle

Refresh Your Home­’s Exte­ri­or Surfaces

Remove years of buildup, moss, mildew, and grime from your home­’s exte­ri­or sur­faces. All Cov­ered Paint­ing pro­vides safe, effec­tive pres­sure wash­ing and soft wash­ing ser­vices tai­lored to the Pacif­ic North­west­’s unique challenges.

Why Pro­fes­sion­al Exte­ri­or Wash­ing Matters

Restore Your Home­’s Appearance

Years of Pacif­ic North­west mois­ture cre­ate moss, mildew, and algae growth that dulls your home­’s beau­ty. Pro­fes­sion­al wash­ing instant­ly restores orig­i­nal col­ors and finishes.

Pro­tect Sur­face Integrity

Organ­ic growth isn’t just unsight­ly, moss and algae retain mois­ture against sur­faces, caus­ing pre­ma­ture dete­ri­o­ra­tion. Reg­u­lar clean­ing extends the life of sid­ing, decks, and walkways.

Pre­vent Slip Hazards

Moss and algae on walk­ways, dri­ve­ways, and decks cre­ate dan­ger­ous slip­ping haz­ards. Thor­ough clean­ing makes out­door sur­faces safer for your fam­i­ly and guests.

Increase Prop­er­ty Value

A clean, well-main­tained exte­ri­or dra­mat­i­cal­ly improves curb appeal and demon­strates pride of own­er­ship, essen­tial for lux­u­ry properties.

Pre­pare for Refinishing

Plan­ning to paint or seal? Pro­fes­sion­al clean­ing pro­vides the clean sur­face nec­es­sary for coat­ings to adhere prop­er­ly and last longer.

Pres­sure Wash­ing vs. Soft Washing

We use the right method for each sur­face to ensure safe, effec­tive clean­ing with­out damage.

Pres­sure Washing

Best for hard, durable surfaces:

• Con­crete driveways

• Stone walk­ways

• Paver patios

• Con­crete foundations

• Mason­ry surfaces

How it works: High-pres­sure water (1,500−3,000 PSI) blasts away stub­born stains, deeply embed­ded grime, and years of accu­mu­la­tion from durable surfaces.

Soft Wash­ing

Best for del­i­cate surfaces:

• Vinyl sid­ing

• Wood sid­ing and decks

• Stuc­co

• Paint­ed surfaces

• Roof clean­ing (see our ded­i­cat­ed Roof Clean­ing page)

How it works: Low-pres­sure appli­ca­tion (under 500 PSI) com­bined with spe­cial­ized clean­ing solu­tions safe­ly removes organ­ic growth with­out sur­face damage.

Our expe­ri­enced team assess­es each sur­face and uses the appro­pri­ate method for opti­mal results.

Rec­om­mend­ed Clean­ing Frequency

Annu­al Clean­ing (Stan­dard)

Most Seat­tle area homes ben­e­fit from annu­al exte­ri­or washing:

• Spring or ear­ly sum­mer pro­vides the longest-last­ing results

• Removes win­ter mois­ture buildup and spring pollen

• Pre­pares sur­faces for enter­tain­ing season

Semi-Annu­al Clean­ing (Enhanced)

Homes with spe­cif­ic con­di­tions ben­e­fit from twice-year­ly service:

• Sig­nif­i­cant shade or tree canopy (accel­er­ates organ­ic growth)

• North-fac­ing sur­faces prone to moss and mildew

• High-mois­ture areas near water features

• Homes in heav­i­ly wood­ed areas

Your Home­’s Spe­cif­ic Needs

Clean­ing fre­quen­cy depends on:

• Sun expo­sure (shad­ed areas require more fre­quent cleaning)

• Sur­round­ing vegetation

• Sur­face mate­ri­als and age

• Pre­vi­ous main­te­nance history

• Your stan­dards for appearance

Your Home Care Advi­sor will rec­om­mend the opti­mal sched­ule based on your prop­er­ty’s conditions.

Ser­vices We Provide

Dri­ve­way Cleaning

Remove oil stains, tire marks, moss, and years of grime from con­crete or paver dri­ve­ways. Pro­fes­sion­al clean­ing restores appear­ance and pre­vents organ­ic growth from caus­ing sur­face deterioration.

Best tim­ing: Spring or ear­ly sum­mer, after win­ter weath­er ends

Walk­way & Path­way Cleaning

Clean con­crete, stone, or paver walk­ways to elim­i­nate slip haz­ards and restore beau­ty. We remove moss, algae, and organ­ic buildup that makes paths dangerous.

Best tim­ing: Ear­ly spring, before out­door enter­tain­ment season

Deck Wash­ing

Gen­tle clean­ing removes mildew, algae, and accu­mu­lat­ed grime from wood or com­pos­ite decks with­out dam­ag­ing sur­faces. Prop­er clean­ing pre­pares decks for seal­ing or staining.

Best tim­ing: Late spring or ear­ly sum­mer, before deck usage peaks

Sid­ing Washing

Soft wash­ing safe­ly cleans vinyl, wood, or fiber cement sid­ing, remov­ing mildew, algae, and oxi­da­tion with­out harm­ing sur­faces or forc­ing water behind siding.

Best tim­ing: Spring or fall, avoid­ing extreme heat

Patio & Porch Cleaning

Clean con­crete, stone, or paver out­door liv­ing spaces to cre­ate invit­ing enter­tain­ment areas. Remove years of buildup and organ­ic growth.

Best tim­ing: Spring, before out­door enter­tain­ing season

Fence Clean­ing

Wood, vinyl, or com­pos­ite fenc­ing ben­e­fits from peri­od­ic clean­ing to remove mildew, algae, and weath­er­ing. Gen­tle meth­ods pre­serve fence integri­ty while restor­ing appearance.

Best tim­ing: Spring, espe­cial­ly before stain­ing or seal­ing wood fences.

Our Clean­ing Process

Step 1: Sur­face Assessment

We inspect all areas to be cleaned, iden­ti­fy­ing sur­face mate­ri­als, con­di­tion con­cerns, and the appro­pri­ate clean­ing method for each area.

Step 2: Preparation

We pro­tect land­scap­ing, remove loose debris, and pre­pare the work area for safe, effi­cient cleaning.

Step 3: Pre-Treat­ment (When Needed)

Heav­i­ly soiled areas or sur­faces with organ­ic growth receive spe­cial­ized clean­ing solu­tion appli­ca­tion before washing.

Step 4: Pro­fes­sion­al Washing

Using appro­pri­ate pres­sure and tech­niques for each sur­face type, we thor­ough­ly clean all des­ig­nat­ed areas.

Step 5: Detail Work

We address edges, cor­ners, and areas requir­ing spe­cial atten­tion to ensure com­plete, even cleaning.

Step 6: Post-Clean­ing Rinse

Sur­faces receive final rins­ing to remove all clean­ing residue and ensure even results.

Step 7: Prop­er­ty Cleanup

We remove any debris, inspect our work, and ensure your prop­er­ty is clean and ready to enjoy.

Pacif­ic North­west-Spe­cif­ic Challenges

Moss Growth

The Seat­tle area’s mois­ture cre­ates ide­al moss-grow­ing con­di­tions. Our clean­ing meth­ods don’t just remove vis­i­ble moss, we treat sur­faces to slow regrowth and pro­tect against future buildup.

Algae & Mildew

Green and black algae thrive in Pacif­ic North­west humid­i­ty. Soft wash­ing with appro­pri­ate solu­tions kills organ­ic growth at the root lev­el, pro­vid­ing longer-last­ing results than pres­sure alone.

Con­stant Moisture

Year-round damp­ness accel­er­ates dete­ri­o­ra­tion. Reg­u­lar pro­fes­sion­al clean­ing removes mois­ture-retain­ing organ­ic mate­r­i­al and pro­tects your sur­faces from pre­ma­ture aging.

Shade & Tree Canopy

Many lux­u­ry prop­er­ties fea­ture mature trees that cre­ate beau­ti­ful shade and per­fect con­di­tions for organ­ic growth. We address these high-chal­lenge areas with proven techniques.

Sur­face-Spe­cif­ic Expertise

Con­crete & Masonry

Dri­ve­ways, walk­ways, patios, foundations

High-pres­sure wash­ing removes deeply embed­ded dirt, oil stains, and organ­ic growth. We adjust pres­sure based on con­crete age and con­di­tion to avoid sur­face dam­age while achiev­ing thor­ough cleaning.

Com­mon issues we address:

• Oil and grease stains

• Tire marks

• Moss and algae in cracks

• Years of accu­mu­lat­ed grime

• Sur­face oxidation

Wood Sur­faces

Decks, fences, wood siding

Gen­tle soft wash­ing pre­serves wood grain and integri­ty while remov­ing mildew, algae, and weath­er­ing. Prop­er tech­nique is essen­tial, too much pres­sure dam­ages wood fibers and rais­es grain.

Com­mon issues we address:

• Mildew and algae growth

• Weath­ered gray appearance

• Tan­nin staining

• Sur­face prepa­ra­tion for stain­ing or sealing

Vinyl & Composite

Sid­ing, decks, fencing

Low-pres­sure wash­ing with appro­pri­ate solu­tions safe­ly cleans with­out dam­ag­ing mate­ri­als. We avoid high pres­sure that can force water behind sid­ing or dam­age vinyl surfaces.

Com­mon issues we address:

• Oxi­da­tion and chalking

• Mildew streaks

• Dirt accu­mu­la­tion

• Col­or fad­ing from buildup

Stone & Pavers

Walk­ways, patios, retain­ing walls

Con­trolled pres­sure wash­ing cleans deep into porous stone and paver joints with­out dis­plac­ing sand or dam­ag­ing sur­faces. We adjust tech­niques based on stone type and age.

Com­mon issues we address:

• Moss between pavers

• Organ­ic staining

• Efflo­res­cence (white min­er­al deposits)

• Joint sand displacement

Safe­ty & Envi­ron­men­tal Responsibility

Sur­face Protection

Dif­fer­ent mate­ri­als require dif­fer­ent approach­es. Our trained tech­ni­cians know the appro­pri­ate pres­sure, angle, and tech­nique for each sur­face type to ensure thor­ough clean­ing with­out damage.

Land­scap­ing Care

We pro­tect plants, flow­ers, and grass dur­ing clean­ing oper­a­tions. Pre-treat­ment includes cov­er­ing sen­si­tive veg­e­ta­tion and post-treat­ment includes thor­ough rins­ing of land­scape areas.

Water Man­age­ment

We man­age water runoff appro­pri­ate­ly, direct­ing it away from land­scap­ing when pos­si­ble and ensur­ing prop­er drainage through­out the clean­ing process.

Eco-Friend­ly Solutions

When clean­ing solu­tions are nec­es­sary, we use envi­ron­men­tal­ly respon­si­ble prod­ucts that break down nat­u­ral­ly and won’t harm your land­scap­ing or local waterways.

Fre­quent­ly Asked Questions

How long does pres­sure wash­ing take?

Aver­age dri­ve­way: 2 – 3 hours Full exte­ri­or home wash­ing: 4 – 8 hours Deck clean­ing: 2 – 4 hours

Time varies based on sur­face area, con­di­tion, and spe­cif­ic ser­vices requested.

Do I need to be home?

Not nec­es­sar­i­ly. Most ser­vices can be per­formed while you’re away. We’ll coor­di­nate access to water sources and con­tact you when work is complete.

Will pres­sure wash­ing dam­age my surfaces?

When per­formed prop­er­ly by trained pro­fes­sion­als using appro­pri­ate tech­niques, no. We assess each sur­face and use the cor­rect pres­sure and method to clean safely.

Can you remove oil stains from driveways?

Most oil stains can be sig­nif­i­cant­ly improved or removed. Old, deeply pen­e­trat­ed stains may require spe­cial­ized treat­ment and mul­ti­ple applications.

What’s the best time of year?

Spring and ear­ly sum­mer pro­vide opti­mal con­di­tions, sur­faces dry quick­ly and results last through enter­tain­ing sea­son. Fall is also excel­lent for prepar­ing homes for winter.

Can you clean in any weather?

We pre­fer dry con­di­tions but can work in light rain for some ser­vices. Heavy rain, extreme heat, or freez­ing tem­per­a­tures require rescheduling.

Will clean­ing kill moss permanently?

Clean­ing removes exist­ing moss and our treat­ments slow regrowth sig­nif­i­cant­ly. How­ev­er, Pacif­ic North­west con­di­tions mean moss will even­tu­al­ly return with­out reg­u­lar maintenance.

Do you seal sur­faces after cleaning?

Seal­ing and stain­ing are sep­a­rate ser­vices. We can coor­di­nate these if desired, as clean sur­faces are essen­tial for prop­er seal­er adhesion.
