A 118-ft Pine Privacy Fence for Sandy Williams in Galveston, TX

Sandy wanted a solid, no-gate pine fence that could stand up to Galveston’s humid coastal air. Here is the fence Mustang built — 118 ft of pine with two horizontal rails, a rot-resistant treatment and a protective sealant — and what those two layers of protection actually do.

The short answer

Mustang Fencing built a 118-foot pine privacy fence for Sandy Williams in Galveston, TX, with two horizontal rails and no gate in this run. The pine received a rot-resistant treatment plus a protective sealant — two different layers of protection against Galveston’s humid, coastal climate.

The job: a 118 ft pine fence, built for a humid coastal yard

Sandy Williams wanted a solid, functional pine fence for his Galveston property: no gate, just a straight 118-foot run with two horizontal rails for added structural integrity. Mustang Fencing recommended pine for the combination of durability, affordability and the clean, light-grained look that suits a Gulf Coast home.

Because Galveston’s climate is humid for most of the year, rot resistance was a priority from the start. The pine received a rot-resistant treatment, and once the fence was up, a protective sealant was applied to guard against moisture.

Rot-resistant treatment and a protective sealant are two different things

“Rot-resistant” can sound like one feature, but on a pine fence it is really two separate layers working together. The first is the wood itself: fence-grade pine is pressure-treated, meaning a preservative is forced into the wood under pressure so it resists decay from the inside, not just on the surface. The Southern Forest Products Association’s own fence table calls for ground-contact treatment on posts and a lighter above-ground treatment on rails and pickets.

The second layer is the protective sealant applied afterward — a surface coating that slows how fast moisture and UV reach the wood. It works with the pressure treatment, but it is not a substitute for it: a sealant alone does not stop decay the way the treatment inside the wood does.

Right, a board with a thin surface sealant coat, labeled slows moisture and UV entry but does not reach beneath the surface. Two different layers behind “rot-resistant” 1.

SURFACE SEALANT A thin coat on the surface Slows moisture & UV entry Does not reach beneath the surface Southern Forest Products Association, Pressure-Treated Southern Pine (2019), Table 3-1; USDA FPL Wood Handbook FPL-GTR-282 (2021), Ch.16. A sealant protects the surface; the pressure treatment is what resists decay.

Fence run post & rail estimator

Straight arithmetic for a run like Sandy’s: total posts for a given run length and on-center spacing, and the total linear feet of rail needed for a 2-rail layout. Not a quote — corners, gates and terrain are not included.

Arithmetic: posts = ceil(run length / spacing) + 1; total rail footage = run length x number of rails. On-center spacing is a common fence-building range (4-8 ft), not a code requirement — ask your installer what spacing a given post size and wind exposure calls for.

Questions we get about this

What did Mustang Fencing build for Sandy Williams?
A 118-foot pine privacy fence in Galveston, TX, with two horizontal rails and no gate. The pine received a rot-resistant treatment and a protective sealant.
Why was pine chosen for this fence?
Pine is durable and cost-effective, and it holds up well in Galveston when properly treated and finished.
Is "rot-resistant treatment" the same as the sealant?
No. The rot-resistant treatment is a preservative pressure-forced into the wood, which resists decay from the inside. The sealant is a separate surface coating applied afterward that slows moisture and UV entry.
Why does this fence have two horizontal rails?
Two rails — a top and a bottom — give the pickets more support along the run, which the job’s own documentation lists as part of the design.
