"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

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, homes with walkout basements, steep driveways, or wraparound porches often require special attention for power washing. Tight side yards and mature landscaping can limit access for equipment. If your property has older brick, stone veneer, or composite decking, these surfaces need tailored cleaning methods to prevent damage. Discuss these features with your contractor to ensure they’re prepared for your home’s unique layout.

Helpful?

In O'Fallon, annual house washing each spring removes winter buildup, while spot cleaning for mold or pollen is common in humid months. Decks and patios benefit from yearly cleaning and timely sealing to prevent moisture damage. Before fall, clear gutters and walkways of debris. Regularly addressing algae on driveways and sealing surfaces before winter helps extend the results of your pressure washing investment in the local climate.

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?

Watch out for contractors who provide quotes without visiting your property. O'Fallon homes feature diverse layouts like sloped lots and walkout basements that require an in-person inspection. Another red flag is ignoring stormwater compliance for pressure washing runoff. Local professionals must manage chemical runoff properly. Finally, avoid anyone who fails to ask about the condition of your brick or mortar, as high pressure damages aging brick joints.
