FAQs

How often should I have my house washed?

We recommend having your home washed at least once per year as part of normal exterior maintenance. Regular cleaning helps remove algae, mildew, mold, dirt, pollen, and other contaminants before they become heavy buildup or begin affecting painted surfaces, siding, brick, trim, and curb appeal.

Can pressure washing damage my home?

Yes, improper pressure washing can damage a home. That is why the cleaning method matters. Cornwell Exterior Cleaning uses the appropriate process for each surface, including soft washing and controlled low-pressure cleaning when needed. Brick, siding, painted surfaces, soffits, fascia, windows, trim, and delicate exterior materials are not all cleaned the same way.  Our goal is to safely remove dirt, mildew, algae, and organic growth while protecting the property and preserving the life and appearance of the exterior surfaces.

Will cleaning with bleach harm my plants or grass?

Plant and grass safety depends on proper chemical mix, careful application, and thorough preparation. Cornwell Exterior Cleaning uses appropriate cleaning solution ratios and takes precautions around landscaping before, during, and after the cleaning process.  Plants, shrubs, and grass near the work area may be pre-wet, carefully rinsed, and protected as needed to reduce the risk of damage. While no exterior cleaning process is completely without risk, care is taken to protect surrounding landscaping as much as possible.

Can mold, mildew, and algae on my home affect my health?

Exterior mold, mildew, and algae are mainly a maintenance and appearance issue, but they can contribute to unhealthy conditions if growth spreads or if moisture problems are present. For people with allergies, asthma, or respiratory sensitivities, keeping the exterior of the home clean may help reduce exposure to mold, mildew, and other organic contaminants around the property. Routine cleaning also helps prevent buildup from spreading and becoming harder to remove over time.
