FAQ

House Washing (Soft Wash) in Diamond Bar: FAQ

Is soft washing safe for stucco?

Yes. Stucco is porous and can be damaged by high pressure, which is why we soft wash it.

Will the cleaning solution hurt my plants?

We pre-wet and rinse landscaping and use biodegradable solutions to protect your plants.

Do you offer house washing in Diamond Bar?

Yes. We soft wash homes throughout Diamond Bar.

How much does pressure washing cost in Diamond Bar?

It depends on the surface, square footage and how dirty it is. National cost guides put most whole-house washes around $212 to $447 and driveways around $100 to $250 (Angi). Loyal quotes most jobs over the phone or from photos.

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

Pressure washing uses high-pressure water for hard surfaces like concrete and pavers. Soft washing uses low pressure plus cleaning solutions for stucco, siding, roofs and painted surfaces, which high pressure can damage.

Is pressure washing safe for stucco, roofs and painted surfaces?

Only with the right method. We soft wash stucco, roofs, siding and paint, and save high pressure for concrete, pavers and masonry flatwork.

How often should I pressure wash my home in Diamond Bar?

Most homes need it once a year, and twice a year near busy roads, the coast or dusty hillsides. Driveways and patios often look best cleaned every 6 to 12 months.

Will the cleaning solutions hurt my plants, pets or kids?

We use biodegradable solutions, pre-wet and rinse landscaping, and let everything dry before pets and kids go back out.

Can you remove oil stains, rust and gum from concrete?

We pre-treat oil, rust, tire marks and gum. Most stains lighten a lot, though very old or deep stains may not disappear completely.

How long does pressure washing take?

A typical house wash takes about two to four hours. Driveways and patios usually take one to two hours.

Do I need to be home and do you need my water?

You don't need to be home. We need access to an outdoor spigot and the areas being cleaned.

Do you pressure wash commercial properties?

Yes. We clean storefronts, sidewalks, drive-thrus, dumpster pads, parking structures and building exteriors, often overnight, with practices that keep wash water out of storm drains.

Should I pressure wash before painting or selling my home?

Yes. Painters need a clean surface for paint to bond, and a washed exterior photographs much better for listings.
