“After three companies told me my 1926 Riverside tile roof couldn’t be cleaned safely, Onyx restored it beautifully. They knew exactly how to handle the original mortar and even matched the patina where tiles had been replaced. No broken pieces or water intrusion—just a clean roof that looks appropriate for the historic district.”

What Our Clients Say
Real feedback from homeowners and businesses who trust Onyx Power Washing to get the job done right.
“The oil stains from my boat trailer had been there so long I thought they were permanent. Not only did Onyx remove them completely, they pointed out where tree roots were lifting my driveway near the curb—saved me from a tripping hazard before my HOA could fine me. Their guy even came back to check the cleaning held up after that big storm last month.”
“Living near Jacksonville Beach means constant salt spray on our siding. Onyx’s pretreatment solution made all the difference—where other companies left streaks, they got our house cleaner than it’s been since we bought it. They took time to cover our delicate hibiscus plants too. Six months later and I’m just now starting to see a little grime come back.”
“Running a seafood restaurant means grease everywhere. Onyx handles our weekly awning and sidewalk cleaning without fail, even during tourist season. Last health inspection, the examiner complimented our dumpster area cleanliness—that’s 100% thanks to their detail work. Worth every penny for avoiding violations.”
“Our dock in San Marco was so slippery our grandkids couldn’t visit safely. Onyx didn’t just clean it—they diagnosed where the sprinkler system was keeping wood constantly damp. Fixed the sprinkler angle and used some miracle cleaner that made the wood look new without being rough on bare feet. Husband says it’s the best home maintenance money we’ve spent.”
“Most power washing companies don’t understand how coquina stone behaves, but Onyx clearly had experience with the older Ponte Vedra homes like ours. They used just enough pressure to remove the green algae without eroding the soft stone. Bonus points for noticing and resealing our outdoor outlets before cleaning—that’s the kind of foresight you only get from local experts.”
