IMPORTANT HOMEOWNER INFO

Do You Have "Chalky" Siding?

Over time, the sun breaks down the top layer of vinyl siding, creating a white, chalky powder. This is called Oxidation.


The "Finger Test": Go outside and run your finger across your siding. If it comes back with white powder, your siding is oxidized.

Why this matters: Standard house washing removes dirt and algae, but it is not oxidation restoration. If your siding is heavily oxidized, simple washing can sometimes reveal uneven blotchiness that was hidden by the dirt. We offer specialized Oxidation Removal as a separate restoration service if needed.

Our Safe Cleaning Process

We treat your home like it's our own. Here is exactly what happens when we arrive.

  1. Plant Protection

We water all plants before, during, and after cleaning to neutralize any soap. We also bag sensitive downspouts.

2. Soap Application

We apply our biodegradable cleaning solution at low pressure. It dwells on the surface, killing algae and mold spores instantly.

3. The Soft Rinse

We rinse the home with a high-volume, low-pressure water stream (like a heavy rain), leaving it spotless.

The 12-Month Algae Free Guarantee

We guarantee our results. If green algae returns to your siding within 12 months of a full house wash, we will come back and spot-treat it for free.

Plant Protection Guarantee
If any of your plants are damaged by our detergents, we will replace them.

FAQS

Here are answers to some common questions. 

  • Will water get behind my siding?

    Absolutely not. High-pressure washers can force water through weep holes and window seals, causing mold inside your walls. We use Soft Washing, which uses no more pressure than a garden hose. It relies on biodegradable soaps to clean, not brute force.

  • Is the soap safe for my plants?

    Yes. We adhere to a strict Plant Protection Protocol. We pre-wet all landscaping with fresh water before applying any soap. This creates a protective barrier. We then rinse the plants again after cleaning. We guarantee your plants will be safe.



  • Will this fix my faded/chalky siding?

    Standard washing removes dirt and algae, but it does not fix oxidation (that chalky white powder caused by sun damage). In fact, washing can sometimes make oxidation more visible. If your siding is heavily oxidized, ask us about our Oxidation Restoration service.



  • How much does it cost?

    Pricing is based on the size (square footage) of your home. We offer free, instant quotes over the phone or online. It is a small price to pay to protect your siding from rot and increase your curb appeal instantly.



  • Does this include window cleaning?

    We rinse the windows, so they will be cleaner than before! However, for a perfect, streak-free shine, we recommend adding our Pure Water Window Cleaning package. We use deionized water to scrub the glass to a spot-free finish.
