Green Algae and Mildew

Concrete Patio Cleaning
Back patios sit in the shade and stay damp, which is exactly where algae and mildew grow. We get yours clean and ready for the grill, the furniture and the next cookout.

Most patios sit right against the back of the house, in the shade for much of the day. Add a grill, furniture that holds water underneath, potted plants and leaves from nearby trees, and a patio can turn dark and green in a single season.
We clean patios the same careful way we clean driveways. Joints get sprayed out, the slab gets surface cleaned for one even finish, and a post treatment soaks into the concrete to brighten it and help it stay clean longer.
Screened and covered patios get the same clean, with extra care around screens, posts and the edges of the house.

Years of backyard life, gone in one visit.

Marks left behind by potted plants, furniture feet and wet leaves.
Foot traffic and dirt tracked in from the yard that a broom never gets.
Yellow pollen and the dark spots left by leaves and pine straw that sat on the concrete.
Patios around Lake Norman get extra shade and humidity, especially behind lakefront homes. We clean them in Charlotte, Cornelius, Davidson, Huntersville and Mooresville.

Highly recommend CaroClean Pressure Washing! We had them clean the exterior of our house along with our driveway, sidewalks, and both our front and back patio areas, and the results were exceptional. The difference before and after was incredible. Areas of the siding and concrete that had built-up dirt, grime, and discoloration look clean and refreshed again.
They did a very thorough job and paid attention to the entire property rather than rushing through it. Our driveway, sidewalks, and patio look dramatically better, and the exterior of the house looks fantastic.
The pricing was also very fair for the amount of work completed. We never felt overcharged, especially considering the quality of the results. We are extremely happy with the work and would absolutely use CaroClean Pressure Washing again. I highly recommend them to anyone looking for professional pressure washing or exterior cleaning!
Excellent service! I’m extremely happy with the work he did on my driveway and home. He was very polite, respectful, professional, and meticulous. He took his time to make sure everything was done properly, and the results look amazing. I highly recommend his services 100%, and I would definitely hire him again in the future. Thank you for the great work!
Caz recently power washed my parents’ home in Mooresville and I cannot say enough amazing things about him! He arrived EARLY (I know, unheard of nowadays), he was extremely knowledgeable of what he was doing and he came up with a game plan for the project and my parents were privy and apart of the process every step of the way. On my behalf of my parents, there aren’t enough stars to share how awesome Caz is. We look forward to working with him in the future. Many people have worked on my parents’ house and Caz is the keeper. His prices are EXTREMELY REASONABLE. great kid, great service!
Caz was wonderful from the very first conversation! He performed an inspection, explained what needed to be done, walked me through what to expect, and provided an estimate. I was able to get an appointment within just two days, which was great. He did an amazing job, and I couldn’t be happier with the service. I highly recommend Caz to anyone looking for professional, reliable, and friendly service!
This is an honest comment Before: our house looked dirty because of accumulation of dust, pollen, drips from vents, etc for several years. After: the house looks incredible clean, just like a new house. All colors came alive again. Arrived on time, listened to our concerns and acted very professionally. Because his quality of work and his affordable pricing, I am considering to continue his services on a 12-18 basis Thank you for the work well done Property owner

The customer service was excellent from start to finish, and it’s clear they take pride in their work. I’m extremely happy with the results and would definitely use them again. If you’re looking for someone who does great work and provides excellent customer service, look no further!
