Pressure Treated Pine Fence Installation in Anderson, SC

Pressure treated pine fence installation is the most common wood fence we build in Anderson County, and it is the right answer far more often than the trade likes to admit. Southern yellow pine soaks up preservative better than almost any species available to us, it is grown and milled close to here, and it costs a fraction of cedar per board.

What separates a treated pine fence that lasts from one that does not is never the species. It is the use category printed on the tag, the metal you fasten it with, and knowing what the wood is going to do over its first two summers. We build treated pine privacy, picket, shadowbox, board on board and rail fencing across Anderson County and Greenville County, plus Easley and Clemson. We quote free on site and take no deposit to hold a date.

What our pressure treated pine fence installation includes

Treated pine is the easiest fence in the trade to quote cheaply by leaving things out. Here is what is in ours.

• On site measure, a line walk with you, and a grade check for where the run has to step
• Standard utility locate request before a single hole is dug
• Southern yellow pine, ground contact rated in the dirt and above ground rated where that is correct
• Every stick pulled by eye on delivery, with twisted and wane heavy boards sent back rather than hidden mid run
• Posts set in concrete in holes dug wide, with the concrete crowned so water sheds off the top
• Hot dipped galvanized or stainless fasteners throughout, rated for copper based preservative
• Gate hardware in the same metals, because a plated hinge on a treated post is a countdown
• Three rails on a six foot fence, cut so joints land on post centers instead of mid span
• Gates built on site as braced frames, sized to still clear the ground once the leaf settles
• Tear out, haul away and post hole spoil raked out flat

Every piece of treated lumber carries a plastic end tag. It names the preservative, the use category the board is rated for, and whether it was dried after treatment. Read it. It is the quickest way to tell whether a cheap quote is cheap because of labor or cheap because of what is in the wood.

When treated pine is the right call

We recommend it more often than any other wood, and for reasons that have nothing to do with it being the cheapest thing on the price list:

• You have a lot of linear feet and the budget has to reach all the way around
• The fence is a boundary and a container, not a feature you study from the patio
• You intend to stain it, because dried treated pine takes color as well as anything we work with
• You want a damaged board in year five replaced for a few dollars from any lumber yard in the county
• You need the fence soon, since treated stock is sitting on a shelf in Anderson today
• You are matching a treated fence a neighbor already built on the shared line

It is the wrong call if you want a wood fence with no maintenance attached and can carry the extra cost. Cedar is the better buy there and we will say so on site. Treated pine rewards attention, and ignored for a decade in this climate it cups, checks and grays in a way that reads as neglected rather than weathered.

Read the use categorySouth Carolina sits in one of the heaviest termite pressure zones mapped in the residential code, which makes the rating stamped on a fence post matter more here than it does in most of the country.

Ground contact or above ground: what the tag is telling you

Treated lumber is not one product. It is sold in use categories, and the two you will meet at a fence yard behave completely differently once they are in Anderson County dirt.

Wet stock, and why the boards move

Most treated fence lumber ships wet. It comes out of the treating cylinder saturated with waterborne preservative solution and goes more or less straight onto a truck. A freshly treated 4x4 can weigh close to twice what the same stick weighs once it has dried. All of that water leaves over the first months on your fence, and as it goes the board shrinks across its width, cups toward the bark side and opens surface checks.

Kiln dried after treatment stock has already been through that. It costs more, it is harder to find in fence grades here, and it moves far less. Most Upstate fences are built from wet stock, which is fine as long as the builder accounts for the shrinkage.

That accounting is a real decision, not a detail. On a butted privacy fence in wet stock we set the boards tight, because a tight board dries into a small gap while a board set with a gap dries into a wide one. On a picket we do the reverse and hold the design spacing, knowing it will open slightly. Getting that backwards is why some one year old fences in this county look like a comb.

How we build a treated pine fence

Same sequence every time, on a hundred feet or on a thousand.

1. Walk the line, confirm corners, set gate positions and mark where the grade forces a step
2. Request locates, then hand flag irrigation heads and low voltage lighting runs
3. Dig post holes wide, with depth set by fence height and wind load rather than by frost, since Upstate frost depth is shallow
4. Set ground contact rated posts in concrete and crown the top so water runs off instead of standing against the wood
5. Let the concrete cure before any rail or panel weight goes on
6. Rails go on next, three of them at six foot, each cut to break over a post
7. Sort boards crown up and hang them with hot dipped or stainless fasteners, two per board per rail
8. Build and hang gates last, braced from the bottom latch corner up to the top hinge corner
9. Rake the spoil, pick up the off cuts and walk the finished line with you

Most treated pine yards run one and a half to three days on site depending on length and gate count. The step we will not compress is the cure. Hanging a heavy, water soaked panel on a post set yesterday afternoon is how a run ends up with a wave no later adjustment takes out.

Treated pine in Anderson County ground and weather

Anderson has a humid subtropical climate with no dry season, which is the fact that shapes everything about a wood fence here. There is no long settled stretch where the lumber gets to reach an equilibrium and stay there. Treated pine on an Upstate fence is wetting and drying all year, and that cycling, rather than decay, is what backs fasteners out, opens gate joints and cups boards away from the rail.

Below grade the story is soil. The Cecil series red clay under most of this county is mapped across more than 10 million acres of the southeastern Piedmont. It is dense and holds its shape, good news for a post, and it drains slowly, which is not. A narrow hole in Cecil clay behaves like a bucket for days after a storm. Above ground rated pine set into that is a short term fence.

The finish window is local too. Wet stock will not accept a penetrating stain, so the advice is to wait, usually a few months to a full season, until water sprinkled on a board soaks in rather than beading. Anderson takes about 48 inches of rain a year against a national average of 38, and with hard summer sun behind it that strips an unfinished pine fence fast. A fence sealed once in its first two years outlasts an identical one left bare.

Close to twice the weightThat is roughly what a freshly treated post weighs against the same stick once it has dried, and every pound of the difference is water on its way out of your fence.

What drives the price of a treated pine fence

We quote on site. These are the factors that actually move the number, in rough order of weight:

• Linear feet of fence
• Height, and whether the boards are four, five or six foot
• Use category on the posts, since ground contact rated stock costs more and we do not substitute down
• Post size, with 4x4 standard and 6x6 at gates, corners and under heavy panels
• Board thickness and width, since a thin dog ear fence and a full 1x6 fence differ at the same height
• Style, since shadowbox and board on board eat more boards per foot than a butted privacy run
• Lumber grade, as a sorted premium board and a bin board are not the same thing
• Gate count, gate width and the hardware to hang them
• Slope, rock, tree roots and old concrete footings in the post line
• Tear out and disposal of the fence standing there now, footings included

Treated pine is the cheapest wood fence we install, which is exactly why it is the easiest one for a quote to hide corners in. Two bids on the same hundred feet can sit a third apart, and the difference is almost always post spacing, post rating and rail count. Ask about those three on every quote you collect, ours included.

Hardware and treated lumber do not get along

Residential lumber moved off the old arsenic based treatment in the early 2000s. What replaced it is copper based, and copper against ordinary plated steel in water is a small battery in which the steel loses. That is why a fence built with bright deck screws can be dropping boards in year five while the wood is still sound.

• Hot dipped galvanized: the working standard, a thick zinc coating applied by dipping rather than plating
• Stainless: the best and the most expensive, worth it on gates and anywhere a rust streak would show
• Polymer coated fasteners rated by the maker for treated lumber: acceptable while the coating is intact
• Electroplated or bright zinc screws: not acceptable on treated pine, and the cheapest box on any shelf
• Bare aluminum in direct contact with treated lumber: avoid it, flashing and some gate hardware included
• Mixed metals at one joint: a stainless hinge bolted through a plated carriage bolt simply fails at the bolt

This covers hinges, latches, post caps, brackets and framing connectors, not only screws. A gate is the worst place on a fence to save four dollars, since its hardware is under load every time someone opens it. Usefully, treated pine stains dark around a corroding fastener, so you can see this starting a year or two before a board comes off.
