Deck Sealing vs staining: Why one lasts 25 years
You know the routine. Every two or three years, you spend a weekend pressure washing, sanding down the peeling edges, and brushing on another coat of stain. It looks great for a summer. Then the cracking starts at the edges. Then the gray spots. Then the peeling. And you’re back at the hardware store, wondering if maybe this time a different brand will actually last.
It’s not the brand. It’s the technology.
Every deck stain on that shelf works the same way: it forms a thin film on top of your wood. That film looks beautiful until UV rays and moisture break it down—which takes about 18 to 36 months in the Southeast. Once the film cracks, moisture gets underneath and stays trapped, actually accelerating the splitting, cracking and warping you were trying to prevent.
DuraSeal uses a fundamentally different approach: a penetrating wood sealant that absorb deep into the wood fibers. Instead of creating a film that will eventually fail, our wood seal chemically bonds with the wood itself, providing protection that lasts 25 years or more.
The key is it stops wood from absorbing moisture every time it rains and drying out when the sun hits it. In the Southeast, these expansion/contraction cycles happen 110 times per year to unsealed deck boards.
Once your deck is protected by DuraSeal, your deck maintains its natural wood appearance while being protected from moisture, mold, and mildew from the inside out. The best part – our 25 year warranty against splitting, cracking, warping and rotting.
One application, properly done by professionals, and your deck is protected for the next quarter century. Your weekends are yours again.

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. And if you sell your home, the warranty transfers to the new owner.
Most people come out ahead in 2-3 years compared to re-staining.
