"Frank the owner of this fine establishment dealt with my husband and me. He was very professional throughout our entire transaction from service pitch, actual pressure washing, and closing of our business together. I appreciated the pride and confidence in his work. My house looks GREAT!!! He was able to remove all the green mold build up! We definitely will be using Complete Power Washing St Louis again...Thank you Frank!!!"

"Talk about service! My husband and I needed our back patio power washed to prep our home to be on the market. The initial plan with another company fell through, but when I did a simple search through Angie's List, Scott with Clean Roof STL connected with me right away. The back patio looks completely different in a GREAT WAY! He even sprayed off the back of the house a bit to help with presentation. Since we are no longer living in the area, Scott sent pictures and called to make sure I was happy with the service. He also made it easy to arrange payment. HIGHLY, HIGHLY recommend."

Pressure Washing FAQs, answered by experts

Prioritize professionals who follow strict stormwater runoff practices to keep chemicals out of local storm drains. Verify that the contractor has experience cleaning common O'Fallon exterior materials, including brick veneer and fiber cement siding. Confirm their policies for weather delays during the stormy spring season. Furthermore, ensure they know how to identify pre-existing freeze-thaw damage on concrete before starting any pressure washing to prevent disputes over property damage.

Helpful?

Assess your property for sloped terrain or walkout basements, which complicate ladder placement and water runoff control. Multi-story homes require extended reach equipment for safe pressure washing. Check the condition of your exterior materials. Older brick veneer homes across MO demand specialized soft-washing techniques to protect deteriorating mortar. Additionally, large three-car garage aprons and heavy tree canopy coverage significantly increase the time and complexity of the job.

Helpful?

Severe biological growth from humid MO summers requires specialized treatments and longer dwell times, extending the timeline. Stubborn clay stains on driveways often demand multiple cleaning passes. Unpredictable spring weather, including sudden rain or temperature drops, forces projects to pause. Additionally, older brick homes require gentle soft-washing approaches that take longer than standard pressure washing. Large properties with extensive concrete surfaces also frequently require a return visit.

Helpful?

In O'Fallon, parking vehicles on freshly cleaned driveways, allowing irrigation overspray on siding, or failing to trim back shrubs can quickly lead to new stains or mildew. Not resealing decks after cleaning, letting acorns or leaves accumulate in corners, and ignoring minor cracks in concrete can also reduce the longevity of pressure washing results. Regularly checking gutters and downspouts helps maintain clean surfaces longer.

Helpful?

Document all pre-existing surface damage, including concrete cracks from O'Fallon freeze-thaw cycles or deteriorating brick mortar. Take photos of these areas before scheduling pressure washing. Note the location of outdoor water spigots, electrical outlets, and nearby storm drains. Record the approximate age of your siding and decks. Finally, compile any neighborhood homeowner association guidelines regarding approved exterior cleaning methods, chemical restrictions, or specific scheduling requirements.
