What to put back when the trim has failed
What to put back when your trim has failed: how the four common materials behave in Georgia humidity, what each costs, and where each is the right answer.

Once a board is coming off, you get a choice that will not come round again for decades. Most people default to matching what is there, which is sometimes right and sometimes repeating a mistake the builder made in 1994. Here is how the four options actually behave in this climate.
Hardboard, which is what most of Woodstock has. Compressed wood fiber and resin, factory primed, used as standard exterior trim across the southeast from the mid eighties to the late nineties. It is dimensionally perfect, it is the cheapest option, and it takes paint well. Its defect is that it is only waterproof while the coating is intact: once the paint film cracks at a joint, a nail head or the bottom edge, the core wicks water, swells and delaminates. Matching it is reasonable if and only if every face including the back and both cut ends gets primed before it goes up, and the house gets repainted on a sensible cycle rather than when it starts to look bad.
Dimensional wood, usually pine or cedar. What the older houses near downtown Woodstock have. It rots, but it rots slowly and from the outside, which means it is visible early and often repairable in place with an epoxy consolidant rather than replaced. Cedar in particular is worth keeping on a period house. The drawback in this county is carpenter bees, which prefer softwood and will keep coming back to it, and the paint cycle, which is shorter than anything else on this list.
Fiber cement, which is what most crews here now recommend by default. Cement, sand and cellulose. It does not rot, it does not wick at a cut edge, insects have no interest in it, and it holds paint roughly two to three times longer than wood or hardboard. It costs meaningfully more per foot, it is heavy and slow to hang, and cutting it is dusty work that a careful crew does outdoors with the right blade. For a fascia run that has failed once already, this is usually the correct answer.
PVC trim, the premium option. Cellular plastic, no rot under any circumstances, no insects, and no painting required unless you want a different color. It is the right material for the specific runs that stay wet: a low rake board over a deck, a section in permanent shade, or the elevation under the gutter that keeps overflowing. Two caveats worth knowing. It expands and contracts noticeably with temperature, so it wants the correct fasteners and gaps at the joints, which is a detail unskilled crews miss. And it costs the most.
Aluminum wrap is a finish, not a material. Wrapping coil stock over existing sound wood ends the painting on that elevation and it is a good upgrade. It is not a substitute for replacing rotten board, and covering rot with metal makes it worse by sealing the moisture in. Treat it as something you do after the carpentry, not instead of it.
How to choose, practically. If you are repairing one section on a house you expect to sell within a few years, match the existing material and paint it properly. If a run has failed for the second time, change material, because the first repair told you what that location does. If the elevation gets hit by carpenter bees every spring, go to something they cannot tunnel into. If the run is over a deck or in deep shade, PVC. Otherwise fiber cement is the sensible default in this climate.
Do not mix materials on one elevation. Different materials hold paint differently and move differently with heat, so a run that is half fiber cement and half hardboard shows the seam within two summers and the joint opens up. If part of a run is going, take the run. The material is cheap compared with the labor of setting up twice.
The last consideration is the one nobody raises: whoever paints it. Every option except PVC and aluminum comes back to paint, and the most common reason a good material fails early is that the back face and the cut ends were never primed. If you take one thing from this page, make it that question. Ask the crew whether they prime all six faces before hanging. The answer tells you almost everything about how the rest of the job will be done.

Common questions
What should I actually replace mine with?
On a hardboard house, fiber cement: it matches the profile, it does not rot, and it takes paint. In a spot that stays wet or shaded, PVC, since it does not care. On an older home where the trim profile is part of how the house looks, real wood repaired or matched, because the modern stock will not sit right.
Why is there a minimum fee for a small repair?
Because the drive, the ladder or staging, the gutter coming down and going back up, and the paint are the same whether the run is four feet or fourteen. A crew that charged strictly by the foot would lose money on every small job and would simply stop taking them. If you have more than one small repair, having them done in the same visit is much cheaper than two callouts.
How do I measure my roofline to get a rough price?
Measure along the ground below each run of gutter and add the runs together, which is close enough for an estimate. A typical single-story Woodstock house has roughly 120 to 150 linear feet of fascia, and a two-story with dormers runs 180 to 250. You only need to measure the sections that have actually failed, not the whole house.
Why does fascia rot so quickly in this part of Cherokee County?
Because the subdivisions were cut out of standing loblolly pine and the builders left as many trees as the plans allowed. Pine needles mat in the gutters rather than washing through, the standing water rises above the back lip, and it spills down the strip of fascia hidden behind the gutter, which is the one part of the board that never gets repainted. Heavy tree cover also keeps the roofline from drying between storms.
