Composite Fence Installation in Anderson, SC

Composite fence installation is usually the phone call that comes after somebody has stained a wood fence twice and decided they are finished with ladders and brushes.

We install composite fencing throughout Anderson County and Greenville County. It is a manufactured board rather than a natural one, and understanding what is actually inside it explains both the things it does very well and the two or three things it does not do at all.

What our composite fence installation includes

Composite is a system. The boards, the rails, the posts and the fasteners come from the same manufacturer and they are engineered to work together, which is why mixing brands mid run is a bad idea.

• On-site measure, a walk of the line and color samples held up against your house before anything is ordered
• Utility locates called in and marked before we put a bit in the ground
• Structural posts, either reinforced composite or a steel or aluminum insert inside a composite sleeve, set in concrete
• Post spacing taken from the manufacturer span table rather than from habit, because composite is heavier than wood
• Boards cut with the right blade and the ends sealed or capped where the system calls for it
• Expansion gaps left at every butt joint and termination, sized for the temperature on the day we install
• Manufacturer fasteners and hidden clips, since the wrong screw voids most composite warranties
• Gates built on a reinforced frame, because composite board has no business carrying a hinge on its own
• Tear out and haul away of the old fence and its footings
• Paperwork handed over, including the warranty registration details for your specific product

That warranty point matters more than it sounds. Composite warranties are long and they are also conditional, and the two conditions that get broken most often are wrong fasteners and post spacing stretched to save a hole.

What composite fencing is, and when it is the right call

A composite board is wood flour mixed with a polymer binder, usually a polyethylene, then heated and forced through a die into a solid or ribbed profile. The wood gives it stiffness and the grain texture. The plastic surrounds the wood particles so water never reaches them, which is the whole reason it does not rot.

The important distinction at the quote stage is capped against uncapped. A capped board carries a hard polymer shell fused over the outside during manufacture, so nothing organic ever touches the wood flour. An uncapped board has wood particles at the surface, and that surface will chalk, weather and hold a stain from mulch, pollen or a leaf that sat there through a wet week.

Composite is the right call in these situations:

• You are done with staining and want that to be permanently true, not true for three years
• The fence line runs somewhere wet, such as a low corner of the yard or against a tree line that stays damp
• You want a wood look but the neighborhood or the HOA wants a consistent finish that will not gray unevenly
• You are matching an existing composite deck or pergola and want the same color family
• You intend to stay in the house long enough for the maintenance savings to actually land

It is the wrong call when you are fencing a large acreage on a tight budget, when the fence is going up to sell the house next spring, or when what you actually want is the smell and the character of real cedar. Composite does a lot of things, but it never stops being a manufactured board.

Composite, pine or vinyl: what you are buying

These are the three materials people put side by side when they are pricing a privacy fence that will not need staining.

The honest way to compare composite against pine is to price the pine fence, then add a wash and restain every few years across however long you plan to own the house, and put both numbers next to each other. We will give you the install figure for either material on the same estimate so you can run that yourself instead of taking our word for it.

How we install a composite fence

Composite goes up in a specific order, and the manufacturer instructions are not suggestions. Here is the sequence on a normal residential job.

1. Walk the line, agree the height, the color and where the gates land, and order the system as a complete package
2. Request utility locates and flag irrigation and low voltage lines
3. Lay out post centers to the span table for that product, not to a generic six foot rule
4. Dig wide holes, set the structural posts in concrete, and crown the footing so water runs away from the post
5. Let the concrete cure before loading a rail or hanging a gate
6. Fit bottom rails first, check level along the run, then stack the boards up into the channels
7. Leave the expansion gap the instructions call for at every butt and termination, adjusted for the temperature that day
8. Cap the posts, fit the top rail, then build and hang gates on reinforced frames
9. Clean up, and hand over the color, batch and warranty details for the product on your fence

Most residential composite jobs run a day or two longer than the same footage in pine. The extra time is in the layout and in the fact that you cannot fudge a composite fence the way you can fudge a wood one. There is no cutting a board a half inch long and forcing it home.

Composite fencing in Anderson County sun and clay

Two things about this county make composite worth the money, and one thing about it means composite still needs to be installed properly. Start with the good news. The residential code puts South Carolina in one of the heaviest termite pressure zones it maps. A treated pine board resists termites because of what was pushed into it at the plant; a capped composite board resists them because there is nothing accessible for a termite to eat.

Then there is water. Anderson takes about 48 inches of rain a year against a US average of 38, in a humid subtropical climate with no dry season. Bare wood in that pattern absorbs and releases moisture constantly, which is what drives cupping, checking and soft board ends. Composite does not absorb it, so the boards you look at in year twelve are dimensionally the same boards that went up.

The part that still needs attention is underground. Cecil series red clay is mapped across more than 10 million acres of the southeastern Piedmont, and it drains slowly, so a post hole holds water long after the storm passes. That does not hurt the composite board, but composite fence posts are usually structural steel or aluminum inside a sleeve, and steel in standing water is steel that corrodes. Wide holes, proper concrete and a crowned footing are as important on a composite fence as on any other.

One of the heaviest termite pressure zones in the codeCovers South Carolina, and composite board offers a termite nothing to work on. The structural posts underneath it are where the attention still belongs.

What drives the price of a composite fence

Composite quotes come out higher than wood, and they vary more between products than wood does between species. These are the drivers:

• Linear feet and height, as with any fence
• Capped or uncapped board, which is the biggest single quality step in the material
• Manufacturer and product line, because composite is not a commodity the way a pine picket is
• Color, with some finishes and multi tone grains costing more per board
• Post type, since a reinforced structural post costs well above a plain sleeve
• Post spacing required by the span table, which sets how many holes we dig
• Gates, which need reinforced frames and heavier hardware than a wood gate
• Slope, because composite panels rack far less than wood and the run has to step
• Tear out and disposal of the existing fence and its old footings
• Access, including how far the boards have to be carried, since they are heavy

That is most of what a composite estimate is: working out whether the extra money is buying you something you will actually benefit from, or whether cedar and a stain schedule is the better spend for your situation.

Heat, fade and movement in full Upstate sun

No material is free. These are composite's real trade offs, and none of them are dealbreakers if you know about them before you buy.

It gets hot

A composite board in direct summer sun runs hotter to the touch than wood does, and a dark color runs hotter than a light one. On a fence this rarely matters, since you are not walking on it barefoot, but it is worth knowing if the fence doubles as a bench back or encloses a small courtyard that already bakes. If the exposure is brutal all afternoon, the lighter colors in the range are the easier choice.

It moves with temperature

Plastic expands and contracts with heat more than wood does, and it does it along the length of the board. That is why every manufacturer specifies an expansion gap at butt joints and terminations, and why the correct gap depends on how warm the material is when it is installed. Boards fitted tight on a cool morning in March can buckle in July. We measure, we check the instructions, and we leave the gap.

It settles in color

Most composite lightens a little during its first season of sun and then holds steady. Capped products hold far better than uncapped, which is the main argument for paying for the cap in a place that gets Upstate summers. If you are adding to an existing composite fence, expect the new boards to sit slightly darker until they have had a season outside.

It is not structural

A composite board is stiffer than plastic and less stiff than a comparable piece of lumber, and it is heavier than both. That is why the span table exists and why posts are reinforced. A composite fence built at wood fence post spacing will sag in the rails, and no warranty covers that.
