Why Your Greenville Deck Needs Penetrating Sealer, Not Stain
The average top-coat lasts 2–3 years. DuraSeal lasts 10x longer.
Stains & Top-Coat Sealers
- Sit on the surface as a film
- UV and moisture break them down in 2–3 years
- Peel, flake, and need constant re-application
- Trap moisture — feeding rot underneath
- New wood must cure 30–90 days first
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
- Protects against moisture, UV, mold & mildew
- Applies to brand-new pressure-treated 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.
Upstate Sun & Freeze-Thaw
Upstate summers bake unprotected wood and winter freeze-thaw cracks it. One sealed application handles both.
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.
