Question 1

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

Accepted Answer

Pressure washing uses high-pressure water to clean hard surfaces like concrete and driveways.
Soft washing uses low pressure and specialized cleaning solutions to safely clean surfaces like siding, roofs, and painted areas without damage.

Question 2

Will pressure washing damage my siding or roof?

Accepted Answer

Not when done properly! That’s why we use soft washing on siding and roofs instead of high pressure. Using the correct method for each surface prevents damage while delivering better, longer-lasting results.

Question 3

How often should I have my house, driveway, or roof cleaned?

Accepted Answer

House washing: once per year
Driveways & sidewalks: 1–2 times per year
Roof cleaning: every 2–3 years
Frequency can vary based on shade, moisture, and surrounding trees.

Question 4

Do I need to be home during the service?

Accepted Answer

No. As long as we have access to water and the areas being cleaned, you don’t need to be home. We’ll let you know when we arrive and when the job is complete.

Question 5

Will pressure washing remove mold, mildew, and algae?

Accepted Answer

Yes. Our exterior cleaning services are designed to eliminate mold, mildew, algae, and organic buildup at the root: not just rinse the surface. This helps prevent rapid regrowth and keeps your home cleaner longer.

Question 6

Can you remove oil stains and rust stains from concrete?

Accepted Answer

We can significantly reduce or remove most oil stains, rust stains, tire marks, and organic discoloration on concrete and pavers. Results depend on how old and deep the stain is, but professional treatment produces far better results than DIY cleaning.

Question 7

Why hire Williams' Pressure Washing Co. instead of DIY?

Accepted Answer

DIY pressure washing often uses the wrong pressure or technique, which can damage siding, roofs, concrete, and landscaping. Williams’ Pressure Washing Co. uses professional equipment, surface-specific methods, and low-pressure soft washing to clean safely and effectively. Our process removes organic growth at the root for longer-lasting results, saves you time and effort, and is fully insured for your peace of mind.

Question 8

What should I do to prepare for pressure washing?

Accepted Answer

Close all windows and doors
Move vehicles away from driveways and sidewalks
Secure pets indoors
Remove lightweight outdoor furniture if possible
If service is scheduled during spring or summer, please ensure that landscaping and grass are consistently watered prior to your appointment.
