Window Cleaning Questions

How often should I clean my windows in Seattle?

Recommended: 2 times per year (Spring and Fall)

Seattle's rainy climate means windows accumulate water spots, pollen, and grime year-round. We recommend:

• Spring cleaning: Remove winter's buildup of rain spots, dust, and debris before summer entertaining
• Fall cleaning: Clear pollen, summer dust, and prepare for the holiday season

Some homeowners with high-visibility windows (large picture windows, storefronts) prefer quarterly cleaning. Homes near construction zones or busy roads may benefit from more frequent service.

Should I clean windows inside and out, or just outside?

Inside and out (In/Out cleaning) provides the best results.

Exterior windows get the obvious dirt — rain spots, pollen, bird droppings, cobwebs. But interior windows collect:

• Fingerprints and smudges
• Cooking residue and grease films
• Pet nose prints
• Dust from HVAC systems
• Condensation residue

When you clean only the exterior, interior grime remains visible. In/Out cleaning delivers the crystal-clear results most homeowners want.

Cost difference: In/Out cleaning typically costs 20-40% more than exterior-only but provides dramatically better results.

Can you clean windows in the rain?

Yes, professional window cleaning works in light rain.

This surprises many homeowners, but professional window cleaning uses squeegee techniques and specialized solutions that work in damp conditions. We avoid:

• Heavy downpours (water sheets faster than we can squeegee)
• Freezing conditions (safety hazard)
• High winds (difficult to control equipment)

Seattle would have very limited cleaning windows if we avoided all rain. Light drizzle is perfectly fine.

How much does window cleaning cost in Seattle?

Seattle window cleaning costs $128–$860 per visit depending on scope and home size.

Additional factors affecting price:

• Number of windows
• Accessibility (high windows, skylights)
• Condition (heavy buildup costs more)
• Specialty glass (French doors, storm windows)

What's included in "full window detail"?

Full window detail includes cleaning of tracks, sills, and screens in addition to glass.

Standard window cleaning covers the glass surface. Full detail adds:

• Tracks: Vacuumed and wiped clean of dirt, dead insects, and debris
• Sills: Cleaned and dried
• Screens: Removed, cleaned, and reinstalled

Full detail is recommended annually or for homes that haven't had professional cleaning in several years.

Gutter Cleaning Questions

How often should I clean gutters in Seattle?

Recommended: 2 times per year (Spring and Fall) minimum

Seattle's trees and rainfall make gutters critical infrastructure. We recommend:

• Spring: Clear winter debris, check for ice dam damage, ensure proper flow for spring rains
• Fall: Clear leaves before the rainy season, install downspout filters if applicable

Homes with significant tree coverage (especially evergreens) may need 3-4 cleanings per year. Homes with minimal trees may manage with annual cleaning.

What happens if I don't clean my gutters?

Clogged gutters cause water damage that can cost $500–$15,000+ to repair.

When gutters clog, water:

1. Overflows and pools at your foundation
2. Backs up under roof shingles, causing leaks
3. Saturates fascia and soffit, causing rot
4. Freezes in winter, creating ice dams that damage roofing
5. Erodes landscaping and creates basement water issues

Common repair costs from neglected gutters:

• Fascia replacement: $500–$2,500
• Ice dam damage: $1,500–$5,000
• Foundation waterproofing: $3,000–$10,000
• Basement flooding cleanup: $1,000–$15,000+

Prevention cost: $300–$540 per cleaning or $610–$1,220/year for our Gutter Protection Program with unlimited clears.

How do I know if my gutters are clogged?

Signs your gutters need cleaning:

• Water overflowing during rain
• Sagging or pulling away from house
• Plants growing in gutters
• Birds or pests nesting
• Staining on siding below gutters
• Pooling water near foundation
• Gutters visibly full of debris

If you can't remember your last cleaning, they're probably due.

What's the difference between gutter cleaning and gutter brightening?

Gutter cleaning removes debris from inside the gutter channel. It's functional maintenance — ensuring water flows properly.

Gutter brightening is exterior cleaning of the gutter face. It removes oxidation, tiger striping (black streaks), and grime from the visible portion of your gutters. It's aesthetic maintenance — making gutters look new.

Most homes benefit from annual cleaning. Brightening is recommended when gutters look streaked or dirty from the ground.

Do gutter guards eliminate the need for cleaning?

No. Gutter guards reduce cleaning frequency but don't eliminate it.

Even the best gutter guards:

• Allow fine debris through (shingle grit, pollen, small seeds)
• Can trap debris on top, blocking water entry
• Need periodic cleaning/maintenance themselves
• Can create ice dam issues in some climates

Gutter guards may reduce cleaning from 2×/year to 1×/year, but "never clean again" is a myth.

Moss Removal & Treatment Questions

Why does my Seattle roof have moss?

Seattle's climate is ideal for moss growth: wet, shaded, and mild.

Moss thrives when:

• Moisture is present (Seattle's 150+ rainy days/year)
• Shade exists (trees, north-facing roofs, neighboring structures)
• Debris accumulates (leaves, needles, dirt provide nutrients)
• Roofs aren't treated (no preventive zinc or copper)

North-facing roof sections often develop moss first. Composition shingles provide texture for moss to grip; cedar shake retains more moisture, making moss worse.

Is roof moss harmful?

Yes. Untreated moss causes significant roof damage.

Moss damages roofs by:

1. Lifting shingles — Moss roots pry up shingle edges
2. Retaining moisture — Trapped water accelerates rot
3. Blocking drainage — Moss dams prevent water runoff
4. Degrading materials — Constant moisture deteriorates roofing

The progression:

• Year 1-2: Moss establishes, appears as green patches
• Year 3-5: Moss spreads, begins lifting shingles
• Year 5-10: Significant damage, potential leaks
• Year 10+: Major repairs or replacement needed

A $500 moss treatment can prevent a $15,000 roof replacement.

How do you remove moss from a roof?

Professional moss removal involves physical removal + chemical treatment.

Our process:

1. Blow debris from roof surface
2. Physical removal — Soft brushing and raking to remove moss
3. Treatment application — Apply moss-killing solution
4. Gutter cleaning — Remove all debris from gutters
5. Optional: Zinc strip installation — Long-term prevention

We never use high-pressure washing on roofs. Pressure washing destroys shingles and voids warranties.

How long does moss treatment last?

Professional moss treatment lasts 6-12 months depending on conditions.

Factors affecting duration:

• Shade level: More shade = faster regrowth
• Tree coverage: Debris = faster regrowth
• Roof pitch: Steeper roofs shed water better
• Treatment type: Professional treatments last longer than DIY

For ongoing protection, we recommend twice-yearly treatment (Spring and Fall) or our Moss Protection Program with Moss-Free Guarantee.

How much does moss removal cost in Seattle?

Seattle moss removal costs $655–$4,310 depending on moss density, home size, and whether gutters are included.

Prices include gutter cleaning on same visit.

Preventive treatment only (no removal): $295–$545/year for 2 treatments

Pressure Washing Questions

How often should I pressure wash my driveway?

Recommended: Once per year for Seattle driveways

Seattle driveways accumulate:

• Algae and moss from moisture
• Tire marks and oil stains
• Leaf tannins and organic staining
• General grime from traffic

Annual pressure washing maintains appearance and prevents permanent staining. High-traffic areas or shaded driveways may benefit from twice-yearly cleaning.

What's the difference between pressure washing and soft washing?

Pressure washing uses high water pressure. Soft washing uses low pressure with cleaning solutions.

Use pressure washing for:

• Driveways and walkways
• Patios and steps
• Garage floors
• Retaining walls

Use soft washing for:

• Vinyl, wood, or painted siding
• Roofing materials
• Stucco and EIFS
• Painted surfaces
• Decks (initial clean)

Using pressure washing on soft wash surfaces causes damage. Professional crews know the difference.

Will pressure washing damage my concrete?

Not when done correctly by professionals.

Risks of improper pressure washing:

• Etching: Too much pressure creates visible lines
• Surface damage: Removes aggregate, pitting surface
• Wand marks: Uneven cleaning leaves stripes

Professional pressure washing:

• Uses appropriate PSI for surface type
• Maintains consistent distance
• Employs surface cleaners for even results
• Pre-treats stains for better removal

DIY pressure washing is the most common cause of concrete damage.

How much does pressure washing cost in Seattle?

Seattle pressure washing costs $150–$2,100+ depending on surfaces and scope.

Condition multipliers:

• Light/maintenance: 0.85× (recently cleaned)
• Moderate: 1.0× (standard)
• Heavy/algae: 1.25× (significant buildup)
• Severe: 1.50× (embedded staining)

House Washing Questions

How often should I wash my house exterior?

Recommended: Every 1-2 years for Seattle homes

Seattle's moisture creates ideal conditions for algae, mildew, and grime on siding. Signs you need house washing:

• Green or black streaking on siding
• Visible mildew or algae growth
• Chalky oxidation (especially on painted surfaces)
• General dinginess or discoloration

North-facing walls and shaded areas need more frequent cleaning.

Is soft washing safe for my siding?

Yes. Soft washing is specifically designed for siding safety.

Soft washing uses:

• Low pressure (similar to a garden hose)
• Specialized solutions that kill algae and mildew
• Professional technique that protects surfaces

Safe for:

• Vinyl siding
• Wood siding
• Painted surfaces
• Stucco
• Fiber cement (Hardie board)
• Brick and stone

The cleaning solution does the work, not the pressure.

What causes the black streaks on my siding?

Black streaks are typically caused by Gloeocapsa magma, an algae that thrives in humid climates.

This algae:

• Feeds on moisture and limestone particles
• Appears as dark streaks (especially on light siding)
• Spreads via airborne spores
• Returns if not properly treated

Professional soft washing kills the algae at the root. DIY scrubbing often removes visible growth but not the underlying organism, leading to rapid return.

Seasonal Maintenance Questions

What exterior maintenance should I do in spring?

Spring exterior maintenance checklist:

1. Windows — Clean interior and exterior after winter buildup
2. Pressure washing — Remove winter grime from hardscapes
3. Gutters — Clear any remaining winter debris
4. Soft wash — Clean siding before summer entertaining
5. Inspect — Check for winter damage to roof, gutters, siding

Spring is cleanup season — preparing your home after Seattle's wet, dark winter.

What exterior maintenance should I do in fall?

Fall exterior maintenance checklist:

1. Gutters — Clear leaves and debris before rainy season
2. Roof — Blow debris, check for damage, apply moss treatment
3. Downspouts — Ensure clear flow, install filters if needed
4. Inspect — Identify issues before winter makes repairs difficult

Fall is protection season — preparing your home for Seattle's 6+ months of rain.

Should I skip maintenance during rainy months?

No. Most professional exterior services can be performed in Seattle's typical weather.

We work in:

• Light rain and drizzle (most Seattle days)
• Overcast conditions
• Cool temperatures

We avoid:

• Heavy downpours
• Freezing conditions
• High winds
• Lightning

If we waited for perfect weather in Seattle, we'd rarely work. Professional techniques and equipment handle normal Pacific Northwest conditions.

Cost & Value Questions

How much should I budget for annual exterior maintenance?

Budget $1,400–$6,000+ per year depending on home size and service level.

Rule of thumb: Budget 1-2% of your home's value annually for all maintenance. Exterior maintenance is typically 20-30% of that total.

Is professional maintenance worth it, or should I DIY?

Professional maintenance is worth it for most homeowners when you factor in time, risk, and quality.

Break-even calculation: If your time is worth $40+/hour, professional service often costs less than DIY when you include your time.

Will regular maintenance increase my home's value?

Yes. Well-maintained exteriors contribute to home value in multiple ways:

1. Curb appeal: Clean homes show better and sell faster
2. Inspection results: Maintained homes have fewer red flags
3. Buyer confidence: Maintenance records demonstrate care
4. Prevent damage: Avoiding repairs preserves structural value

Estimated impact:

• Clean, well-maintained exterior: +3-5% faster sale
• Documented maintenance history: +buyer confidence
• Prevented damage: Avoids $5,000-25,000+ in potential repairs

On a $800,000 Seattle home, well-maintained exterior can mean $20,000-40,000 in preserved or enhanced value.
