Sealing and staining is the simplest, most cost-effective way to extend the life of a timber dock and keep it looking great. Jordan Marine Construction seals and stains docks and waterfront decks across Greater Houston, Lake Conroe, Lake Livingston, and the Texas Gulf Coast.
Regular sealing protects timber from sun, moisture, and wear, slows graying and splintering, and helps you get the maximum service life from your dock before any repair is needed.

-
Surface Assessment
We check the condition of the timber and flag any boards or hardware that should be repaired before sealing.
-
Prep & Clean
We clean and prepare the surface so the sealer or stain bonds properly.
-
Seal / Stain
We apply quality marine-appropriate sealer or stain in your chosen finish.
-
Protect
We advise on a re-seal schedule to keep your dock protected long term.
Protection That Extends Dock Life
We use quality sealers and stains suited to the marine environment and your timber. Pairing periodic sealing with minor repairs is the cheapest way to maximize the lifespan of a timber dock.
The Cheapest Years of Life You Can Buy a Timber Dock
Every timber dock in Texas is in a slow fight with two enemies: UV radiation breaking down the wood's surface fibers (that's the graying), and moisture cycling — soaking, baking, swelling, shrinking — that opens checks and splits and lets rot get a foothold. Sealing interrupts both. A quality penetrating sealer sheds water instead of absorbing it and screens UV, and reapplied on schedule it can add years of service life to the same boards for a small fraction of what replacing them costs.
Timing matters more than most owners realize. Sealer protects sound wood; it doesn't resurrect damaged wood. The right moment is before the surface breaks down — when water stops beading on the boards, it's time. Wait until boards are deeply checked and splintering, and the honest answer becomes selective board replacement or re-decking rather than a finish coat over failure.
Preparation is most of the job done right. We clean the surface properly, strip failed finish where needed, let the timber dry to accept the product, and flag any boards or hardware that should be repaired before sealing — because sealing over a problem just makes the problem harder to see.
Sealers, Stains, and a Schedule Built for Gulf Coast Exposure
Clear sealers preserve the natural timber look while adding water repellency — the trade-off is less UV protection, so color fades faster. Tinted and semi-transparent stains add pigment that meaningfully improves UV resistance while keeping grain visible, and they're the sweet spot for most docks. Solid stains maximize protection and color uniformity on older surfaces that have already weathered unevenly. We use quality marine-appropriate products matched to your timber's condition and the look you want.
Exposure sets the schedule. A dock in full southern sun over reflective water weathers dramatically faster than a shaded one, and horizontal surfaces (decking) fail before vertical ones (rails and skirting). For most Texas docks, re-sealing every couple of years keeps the protection intact — we recommend a specific schedule for your dock's exposure when we do the work, and pairing the visit with a quick condition check catches small problems while they're small.
Sealing pairs naturally with minor repair: a board here, a fastener set there, a rail tightened — the kind of small-item maintenance that, done consistently, is what separates docks that last forty years from docks rebuilt at twenty.

Dock Sealing & Staining FAQs
How often should I seal my dock?
It varies with sun and water exposure, but many timber docks benefit from re-sealing every couple of years. We will recommend a schedule for your specific dock.
Can sealing fix a graying or splintering dock?
Cleaning and sealing can restore appearance and slow further damage on sound timber. Badly damaged boards are better replaced — we can re-deck where needed.
How much does professional dock sealing cost?
It scales with square footage and prep condition — a maintained dock needing clean-and-seal is quick; a weathered one needing stripping and drying time is more involved. It remains one of the least expensive services we offer relative to the life it adds. Estimates are free.
When is the best time of year to seal a dock in Texas?
Any stretch of dry, moderate weather works — the timber needs to be dry through, and the product needs cure time before rain. Spring and fall are ideal; the heat of high summer accelerates flash-drying, and we plan application accordingly.
Can a gray, weathered dock be brought back to looking new?
Often, yes — proper cleaning removes the oxidized gray surface layer and restores much of the original tone, and a tinted stain finishes the recovery. What cleaning can't fix is deep checking, splintering, and rot; those boards we recommend replacing first, then sealing the restored surface.
Should composite decking be sealed?
No — composite like MoistureShield needs only soap-and-water cleaning, which is a core part of its value. Sealing and staining apply to timber surfaces. If your timber dock's maintenance cycle has become a burden, re-decking in composite ends it permanently.
Does sealing help prevent splinters?
Yes. Splintering is dried-out surface fiber breaking loose — exactly the degradation sealing slows. A dock kept on a sealing schedule stays barefoot-friendly for decades; one left bare develops splinters as the surface breaks down under UV and moisture cycling.
