Sundog Power Wash

One trusted crew for the whole exterior

From siding and roofs to driveways, windows, gutters, and holiday lights — every service uses the gentle, lasting soft-wash approach your home deserves.

01 — House Washing

House Washing

A gentle soft wash that lifts mildew, pollen, and grime without ever touching your siding with high pressure.

Before and after soft-wash house washing on vinyl siding in Williamson County, TN

Middle Tennessee humidity feeds mildew and algae on siding fast, especially on the shaded, north-facing side of the house. We soft wash — not pressure wash — using low pressure under about 500 PSI paired with the right cleaning solution for your surface, so growth is killed at the root instead of just rinsed off the top.

Kills growth at the root, not just the surface

A biodegradable detergent breaks down mildew and algae at the root, so the result lasts noticeably longer than a quick high-pressure rinse.

Safe for paint, siding, and landscaping

Running roughly 60–150 PSI protects paint and caulking instead of driving water behind panels or stripping finish.

Built for brick, Hardie board, vinyl, and stucco

From established brick in older neighborhoods to Hardie board on newer builds, soft washing is gentle enough for all of Williamson County's common exterior materials.

FAQ

House Washing questions

Is soft washing safe for vinyl siding?+

Yes — it's the safer method. High-pressure washing can force water behind vinyl panels and damage the substrate; soft washing uses low pressure and lets the cleaning solution do the work.

How often should I have my house washed in Middle Tennessee?+

For most Williamson County homes, an annual house wash is a good rhythm, ideally in late spring after the heavy pollen season subsides in late April or May. Homes with dense tree cover or persistent mildew on shaded, north-facing walls may benefit from washing more than once a year.

Will the detergent hurt my plants or pets?+

We take that seriously and build plant protection into the job — pre-wetting landscaping, tarping where needed, using biodegradable and neutralized solutions, and rinsing thoroughly when we're done.

Why do the green and black streaks keep coming back on the shaded side of my house?+

Middle Tennessee's warm, humid air feeds mildew and algae, and north-facing or tree-shaded walls stay damp and shaded longest, so they bloom first and worst. A quick high-pressure rinse only knocks the surface off; soft washing with the right detergent kills the growth at the root, which is why a proper wash stays clean noticeably longer.

02 — Roof Washing

Roof Washing

Low-pressure treatment that kills the algae behind black streaks and adds years to your shingles.

Before and after of a roof soft wash removing black algae streaks

Those dark vertical streaks running down the north-facing side of a Franklin roof aren't dirt, and they won't rinse off in the rain. That's Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in shingles and builds a dark, UV-protective coating gravity pulls into streaks. We clean roofs the way shingle manufacturers and roofing associations actually recommend: soft washing, with low pressure and the correct cleaning solution — never a pressure washer on shingles.

Kills the algae, not just the surface stain

The treatment kills Gloeocapsa magma at the root, and results typically last 2–5 years — far longer than a surface rinse.

Zero high pressure on your shingles

High pressure strips the protective granule layer and can void manufacturer warranties. We never use it on a roof.

Protects shingle life and your warranty

Soft washing is the shingle-safe method — it preserves the UV and weather protection your roof depends on.

The plan

How we do it

  1. 1

    Walk the roof plan and protect surrounding property and landscaping

  2. 2

    Apply the low-pressure soft wash solution and let it dwell

  3. 3

    Controlled rinse, with plants rinsed afterward

  4. 4

    Final walkthrough with care timeline guidance

FAQ

Roof Washing questions

Will this void my roof warranty?+

Pressure washing can void most shingle manufacturer warranties. Soft washing at low pressure with a roof-safe solution is the method most manufacturers actually recommend.

What causes the black streaks on my roof?+

The black streaks on asphalt shingle roofs are Gloeocapsa magma, a cyanobacteria that feeds on moisture and the limestone filler used in shingles. It thrives in Middle Tennessee's heat and humidity, and is worst on shaded, north-facing roof planes that stay damp the longest.

What roof types can you clean?+

Asphalt, metal, and tile roofs.

03 — Concrete Cleaning

Concrete Cleaning

Driveways, walkways, patios, and pool decks restored to an even, swirl-free finish.

Before and after concrete driveway and walkway cleaning in Williamson County, TN

Professional concrete cleaning uses a flat surface cleaner paired with the right pressure and targeted chemistry to handle what Middle Tennessee throws at concrete: iron-rich clay, humidity-fed algae, freeze-thaw wear, and everyday rust and oil.

Even, swirl-free finish

A flat surface cleaner attachment gives consistent results edge to edge, without streaking.

Built for Tennessee red clay

Targeted chemistry lifts iron-rich clay staining that a garden hose can't touch.

Sets up sealing protection

Cleaning first means any follow-on sealing bonds properly and lasts longer.

The plan

How we do it

  1. 1

    Walk the surface and identify stains

  2. 2

    Pre-treat and protect surrounding areas

  3. 3

    Surface-clean for uniform, swirl-free results

  4. 4

    Rinse, inspect, and walk it with you

FAQ

Concrete Cleaning questions

Will pressure washing damage my concrete?+

No — concrete is durable enough for higher-pressure cleaning, unlike siding or roofing. We use a surface cleaner attachment for even results without streaking.

Should I seal my concrete after cleaning?+

Sealing right after cleaning protects the surface and makes the next cleaning easier — see our concrete sealing service.

04 — Concrete Sealing

Concrete Sealing

We seal after cleaning so Tennessee clay, oil, and freeze-thaw can't take hold again.

Before and after concrete sealing on a gated driveway, showing richer color and sheen

Middle Tennessee's red clay is iron-oxide rich and bonds aggressively into unsealed concrete pores. Humid summers feed mildew, and winters bring repeated freeze-thaw cycles. Sealing is the protective step after cleaning — it lifts existing stains first, dries fully, then applies a sealant that either soaks in or films over the surface.

Repels red-clay and oil stains

Sealed concrete resists staining instead of absorbing it.

Resists freeze-thaw spalling

Sealant protects against winter cracking and surface damage.

Makes future cleaning easier

Stains wipe off instead of setting in, extending time between deep cleans.

The plan

How we do it

  1. 1

    Clean and treat the surface first

  2. 2

    Let it dry fully

  3. 3

    Choose the right sealant — penetrating vs. film-forming

  4. 4

    Apply evenly and clean up

  5. 5

    Set your reseal reminder — every 2–3 years

FAQ

Concrete Sealing questions

How long does sealing last?+

Typically 2–3 years depending on sealer type and traffic/weather exposure — we'll set a reseal reminder with you.

Penetrating or film-forming sealant?+

It depends on the look and protection level you want — we'll walk through the options for your specific concrete when we quote the job.

05 — Window Cleaning

Window Cleaning

Inside and out, glass to sills, with a tidy site and an on-time arrival you can plan your day around.

SUNDOG crew cleaning second-story windows with an extension pole

We use purified water and squeegee technique to remove pollen film and hard-water spots from interior and exterior glass, screens, tracks, and sills. Cedar and oak pollen coats glass from February into May, humidity feeds haze on shaded north-facing panes, and mineral-heavy spray from sprinklers and hoses dries into spots — all of it comes off.

Purified-water finish

A spot-free rinse means no mineral streaking left behind to dry.

Glass, screens, tracks, and sills

The whole window system gets attention, not just the pane.

Pairs naturally with a house wash

Bundle for a full-exterior refresh in one visit.

The plan

How we do it

  1. 1

    Walk the home and set expectations

  2. 2

    Protect the space around each window

  3. 3

    Clean glass, frames, tracks, and screens

  4. 4

    Purified-water rinse for a spot-free finish

  5. 5

    Final pass and walkthrough

FAQ

Window Cleaning questions

Do you clean interior windows too?+

Yes — inside and out.

What causes the haze on my north-facing windows?+

Shaded, humid conditions hold pollen film and moisture longer on north-facing glass, which is why those panes need attention most often.

06 — Gutter Cleaning

Gutter Cleaning

Clogs cleared and that black tiger-stripe oxidation scrubbed off the gutter faces.

Before and after of a gutter cleared of leaves and debris

Gutter cleaning removes leaves, pine needles, seed pods, and grit from a home's gutters and downspouts so storm water drains away from the roof, fascia, and foundation. In Middle Tennessee's heavy tree canopy it's best done twice a year — late spring after pollen and seed drop, and again in late fall after the leaves come down.

Gutters that actually drain

Cleared downspouts mean water goes where it's supposed to during a storm.

Tiger-stripe brightening included

We scrub the black oxidation streaks off the gutter faces, not just clear the inside.

Fascia and foundation protection

Overflow damage is far more expensive than the cleaning would've been.

The plan

How we do it

  1. 1

    Walk and assess

  2. 2

    Clear by hand and bag the debris

  3. 3

    Flush downspouts and test the flow

  4. 4

    Brighten the gutter face

  5. 5

    Clean up and confirm

FAQ

Gutter Cleaning questions

How often should gutters be cleaned?+

Twice a year for most homes in Middle Tennessee's tree canopy — late spring after pollen/seed drop, and late fall after leaves come down.

What if my downspouts are clogged, not just the gutters?+

We flush and test every downspout as part of the service — a clogged downspout defeats the purpose of clearing the gutter above it.
