Trusted By Our Community
After three different companies failed to fully remove the black streaks from our roof near the Intracoastal, Onyx got it completely clean. They pointed out some loose shingles we hadn't noticed and recommended zinc strips that have kept it cleaner longer.
Our 1920s Riverside bungalow had decades of grime on the original wood siding. Onyx treated it like a museum piece - used just enough pressure to clean without damaging the fragile surfaces. The difference in curb appeal is remarkable.
The driveway at our Ponte Vedra home looked brand new after Onyx worked on it. They even removed old oil stains from the previous owner's boat that I thought were permanent. No damage to the adjacent oyster shell landscaping either.
Our St. Augustine ice cream shop needs frequent sidewalk cleaning near the historic district. Onyx comes like clockwork before our busy weekends, using methods approved by the preservation board. Never had a complaint about slippery surfaces.
The dock at our Mandarin home was turning black with mold until Onyx brought it back to natural cedar color. They discovered some rotten boards we replaced before they became a safety issue. Now we seal it annually.
Living near Jacksonville Beach means constant salt spray. Onyx's treatment removed the white crust from our siding and the mildew from north-facing walls. Our home looks 10 years younger and the cleaner didn't harm our hibiscus plants.
