Johns Creek

Restoration Wash in Johns Creek, GA, specializes in pressure and soft-wash cleaning for homes, targeting driveways, decks, siding, and other exterior surfaces. Using high-pressure water and targeted detergents, they remove dirt, mold, mildew, and stains to restore surfaces like concrete, wood, and vinyl.

This service is tailored to the specific needs of homes in the area, where humidity and seasonal changes accelerate buildup on exterior surfaces.

We also handle Chimney Exterior Cleaning and Mailbox Cleaning for Johns Creek properties.

Signs your home needs exterior cleaning

Exterior surfaces in Johns Creek often show buildup gradually, making it easy to overlook until it becomes noticeable. Green or black streaking on siding, especially on shaded or north-facing walls, is a common sign of algae or mildew.

These stains spread over time and leave a chalky residue when touched, indicating chemical breakdown of the surface.

Another clear indicator is the accumulation of cobwebs, dirt, and insect debris in corners, under eaves, or around light fixtures. These areas collect grime first and can reveal how much the rest of the siding has faded or dirtied.

Removing mounted items like house numbers or small planters can also highlight the contrast between covered and exposed surfaces, showing the extent of dirt and discoloration.

Check for These Before Booking

Green or black streaking on siding, especially on shaded walls (algae/mildew).
Chalky residue when running a hand across the surface (oxidation or grime buildup).
Cobwebs or debris collecting in corners, under eaves, or around fixtures.
Uneven streaking or banded patterns on light-colored vinyl siding (inconsistent cleaning).

What affects cleaning results and cost

The effectiveness of exterior cleaning depends on factors like surface material, moisture exposure, and pre-existing conditions. For example, vinyl, wood, and fiber cement siding each require different pressure levels and detergents to avoid damage.

Areas with persistent moisture—such as those near vegetation or under sprinkler heads—will show buildup faster and may need more frequent attention.

Pricing for exterior cleaning varies based on the scope of the job, surface types, and site conditions. For instance, a full house exterior wash typically ranges widely, and the final cost depends on the specific surfaces included, like driveways, decks, or roofs.

Targeted changes, such as trimming back vegetation or adjusting sprinkler heads, can also extend the time between cleanings.

Avoiding common cleaning mistakes

Pressure washing done incorrectly can cause more harm than good. Using high pressure directly on siding seams or lap edges can force water behind panels, leading to mold growth or rot inside wall cavities.

Similarly, inconsistent wand speed during cleaning can leave streaked or uneven patterns, particularly on light-colored surfaces like vinyl.

Choosing the wrong pressure setting for the material—such as using concrete-level pressure on stucco or fiber cement—can crack panels or strip factory finishes. Pre-treatment with the correct detergent is also critical, as it chemically breaks down algae and mildew before rinsing, rather than relying solely on pressure.

What to Watch For

Zebra striping (uneven cleaning bands) and water forced behind siding are red flags for improper technique. These issues can damage surfaces and may void warranties on materials like vinyl or fiber cement.

How exterior cleaning works

This process combines targeted detergents and controlled pressure to safely restore surfaces without causing damage.

1
Surface and Plant Protection
Landscaping near the foundation is wetted down and covered, and exterior outlets or fixtures are bagged to prevent detergent runoff or overspray damage.
2
Detergent Pre-Treatment
A cleaning solution formulated for the specific siding material—vinyl, wood, stucco, or fiber cement—is applied at low pressure and left to dwell, breaking down algae and mildew chemically.
3
Soft-Wash Rinse
The siding is rinsed at low pressure (under 500 psi) using a wide-fan tip, working top to bottom in overlapping passes at a consistent speed to avoid streaking.
4
Spot Treatment and Final Inspection
Areas with heavier stains receive a second, concentrated pass. After rinsing, the surface is inspected in daylight for missed spots or damage, ensuring no panels are lifting or cracked.

Frequently asked questions

How do I know if my siding needs cleaning or if it’s just normal wear?

Look for green or black streaking on shaded walls, chalky residue when touched, or uneven streaking patterns. These signs indicate algae, mildew, or oxidation rather than just dirt. Comparing covered patches (like under mounted items) to exposed areas can also reveal how much the rest has faded.

Will pressure washing damage my siding or roof?

Pressure washing can damage surfaces if the wrong pressure or technique is used. For example, concrete-level pressure on stucco or fiber cement can crack panels, while forcing water behind siding seams can cause mold or rot. A professional uses low pressure (under 500 psi) and targeted detergents to avoid these issues.

How often should I clean my exterior surfaces to keep them looking new?

Frequency depends on moisture exposure, sun, and vegetation. Shaded or north-facing walls, areas near sprinklers, or sections touched by plants will need attention more often. Trimming back vegetation and keeping gutters clear can help surfaces stay cleaner longer.

What’s the difference between pressure washing and soft washing for siding?

Pressure washing uses high pressure to blast away dirt, which can damage delicate surfaces like siding or roofs. Soft washing uses low pressure (under 500 psi) combined with targeted detergents to chemically break down stains, making it safer for materials like vinyl, wood, and fiber cement.

Common Questions About Pressure Washing in Johns Creek

Everything you need to know about pressure washing services in Johns Creek

How much does Restoration Wash typically cost in Johns Creek, GA?

Driveway and walkway cleaning commonly runs around $0.15 to $0.35 per square foot, while a full house wash — siding, typically using a lower-pressure soft-wash method — more often falls in the $200 to $500 range depending on square footage and stories. Roof cleaning, which requires the gentlest method of the three, tends to price separately and higher per square foot than driveway work. A quote that doesn't separate these surfaces by method and price isn't giving a full picture of what's actually being done.

Why does algae and mildew growth on homes in Johns Creek, GA come back so quickly?

Sustained humidity keeps siding, roofing, and shaded concrete damp for longer stretches than drier climates allow, and algae specifically thrives on that lingering moisture combined with organic debris like pollen and leaf litter. A house washed once and left alone in a consistently humid climate can show visible regrowth within months rather than the year or more typical in a drier region. That's the main reason humid-climate homes are often recommended a twice-a-year schedule instead of once.

Is renting a pressure washer and doing the job at home a reasonable option?

For a driveway or patio, a rented consumer-grade pressure washer can produce a reasonable result with some care about angle and distance. Siding, stucco, and especially roofing are a different story — those surfaces are more forgiving of soft washing's lower pressure than a rented unit's fixed higher pressure, and the risk of gouging siding or lifting shingle granules is real without experience judging pressure and distance. Starting with the lowest effective pressure and testing an inconspicuous spot first reduces that risk.

How long does washing a typical house exterior take?

A single-story home's siding and walkways often take two to four hours including pre-treatment dwell time, while two-story homes or properties that include roof cleaning can run half a day or more. Heavy algae or mildew buildup that needs a longer dwell time, or extensive hardscaping — multiple walkways, a large patio, a long driveway — both add meaningfully to that estimate beyond square footage alone.

Can pressure washing damage concrete, pavers, or mortar joints?

Yes, particularly with older or already-deteriorating mortar and with paver joints filled with polymeric sand — too much pressure at close range can blast the sand or mortar right out of the joints, which then need refilling. Newer or well-sealed concrete generally tolerates higher pressure than older, more porous concrete that hasn't been sealed in years. A wider fan-tip nozzle held at a greater distance is the typical adjustment made where joint or surface erosion is a concern.

What are the actual named steps in a professional pressure washing job?

A typical job moves through pre-treatment — applying a cleaning solution to break down dirt, mildew, or algae before any water pressure is used — dwell time, letting that solution sit long enough to work, often 5 to 15 minutes, rinsing at a pressure and nozzle angle matched to the surface, and a post-treatment step for delicate surfaces like sealing a driveway or applying a mildew-inhibiting rinse. Skipping the pre-treatment and dwell steps and going straight to high pressure is a common shortcut that leaves embedded dirt behind.
