Frequently Asked Questions About Exterior Cleaning

Are there health risks associated with mold, mildew, and algae?

Yes, there are health reasons to power washing your home. Mildew and mold are not good to inhale and can create allergies and other threatening conditions. A regularly washed home helps prevent mold and mildew from spreading into the interior of the house, decreasing the health risks significantly.

Can power washing damage exterior surfaces of my home?

Different surfaces require different pressure settings on the equipment. Every type of surface requires a unique setting. Improper settings can cause serious damage to the roof, vinyl siding, and wooden deck surfaces. Our highly trained power washing technicians are experts on the needs and requirements for each type of surface we clean. You can be sure that exterior surfaces on your home will not be damaged.

Soft washing is almost always recommended for washing roofs. Soft washing uses much lower pressures and detergents to effectively and safely wash your roof.

Will power washing harm my plants and animals?

Power washing is safe for plants, pets, and people when materials and equipment are handled safely, and the work is done properly. We use self-neutralizing cleaning and rinsing agents. Only the best biodegradable and non-abrasive detergents and rinsing agents are used to treat your home.

How often should I have my house washed?

It depends on the brand, material, and color of your siding as well as the climate. In The Woodlands, homes need washing every 2 to 3 years. Some of the lighter colors of siding that are in the shade for much of the day a lot may require washing every year due to faster mold, mildew, and algae growth.
