Mold and Mildew in the Grooves
The dark growth that settles into the grain pattern and the gaps between boards.
Trex and Composite Decks
Composite Deck Cleaning in Lake Norman, NC
Composite decks don't rot, but they still grow mold and mildew in the grooves and collect dirt along the edges. We clean Trex and other composite brands the way they're meant to be cleaned.
Low Maintenance Doesn't Mean No Maintenance
Composite decking is built to last, and that's why so many homes around Lake Norman have it. What it doesn't do is stay clean on its own. Mold and mildew grow in the grain pattern and the grooves, pollen and dirt settle along the edges, and dark spots show up under planters, grills and furniture.
Composite needs a gentle clean, not a blast. Too much pressure can scuff or mark the surface. We clean composite with a solution and pressure matched to the material, so the growth comes off and the boards keep their finish.
Railings, stairs and fascia boards get cleaned too, so the whole deck matches. We clean decks only, so you get clean boards back without any staining or sealing.

I highly recommend this power washing service! They did an amazing job cleaning my deck—it looks better than I ever expected. They were professional, polite, respectful, and paid close attention to detail.

g e r a l d W.Deck cleaningGoogle 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!

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!
Chloe S.House washing in Mooresville, NCGoogle 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!

Can you pressure wash a Trex deck?
Composite should be cleaned gently. Too much pressure can scuff or mark the boards, so we use a solution and pressure matched to composite.
Why is my composite deck getting black spots?
That's usually mold and mildew growing in the grain of the boards, especially on decks that sit in the shade.
Do you stain or seal composite decks?
No. We clean decks only. You get clean boards back, ready to enjoy.
How often should a composite deck be cleaned?
About once a year for most decks, ideally in spring so it's ready for summer.
