Seal Your Jacksonville Dock Once. Protected for 25 Years.
Don't stain it — DuraSeal it. Our penetrating sealer soaks deep into the wood and fossilizes it from the inside, backed by a 25-year transferable warranty. No peeling. No flaking. No re-staining every 2–3 years.
Free, no-obligation quote — good for one full year.
Why Your Dock Needs Penetrating Sealer, Not Varnish
Docks live the hardest life wood can live — water below, sun above. Seal it once, from the inside.
Stains & Marine Varnishes
- Sit on the surface as a film
- Sun and water strip them within a few seasons
- Peel, flake, and need constant re-coating
- Trap moisture against the wood — feeding rot at the waterline
- New dock wood must cure before coating
The DuraSeal Difference
- Soaks 4–6 inches into the wood and chemically bonds
- Fossilizes the structure from the inside
- Wood still breathes — no trapped moisture, no rot
- Stands up to constant water, sun, and weather
- Applies to brand-new dock wood immediately
- One application. 25-year warranty. Done.

Clean & Seal
We pressure-wash your deck, then apply the penetrating sealer that absorbs deep into the wood fibers.
Protected for 25 Years
If the sealant ever fails to protect the way we said it would, we come back and fix it at no charge.
Beats Re-Staining on Cost
Most homeowners come out ahead in 2–3 years compared to the re-stain cycle — then save for decades.
Salt, Brackish & Sun
Brackish water and year-round sun destroy coatings fast. Penetrating sealer lives inside the wood, not on it.
65+ Years of Proof
The sealing technology has been protecting structures for over six decades, with wood-rot studies to back it.
New Deck? Perfect Timing.
Unlike stain, DuraSeal applies to new pressure-treated wood immediately — protect it from day one.
A 25-Year Warranty That Transfers With Your Home
"If our sealant fails to protect your surface the way we said it would, we come back and fix it at no charge — for up to 25 years." Selling your house? The warranty goes to the new owner — a real selling point.
