Keep Water Out by Fixing Damaged Trim

Exterior Trim Repair and Replacement in Barnhart

When the trim around your windows, doors, or roofline starts to rot, crack, or pull away from the wall, it creates openings where water can reach the framing and sheathing. In Barnhart, where rain and humidity are common and wood trim is exposed to moisture year-round, damaged trim often leads to bigger problems like rotted sills, mold behind siding, and drafts that raise your heating and cooling costs.

McCoy's Exteriors repairs and replaces exterior trim to restore protection and maintain a clean, finished look on your home. We remove rotted or damaged sections, treat the underlying wood if needed, and install new trim that fits tight and sheds water properly. Every piece is primed, painted, and sealed to prevent moisture from getting in and causing the same issue again.

If you've noticed peeling paint, soft spots, or gaps around your trim in Barnhart, contact McCoy's Exteriors to have it inspected and repaired.

How do you prevent trim from rotting again?


We start by removing the damaged trim and checking the wood behind it for rot or water staining. In Barnhart, we often find that trim around windows and door frames has been wicking water for months or years, so we dry out the area, treat it with a wood preservative, and replace any rotted framing before installing new trim. New boards are cut to fit, fastened with stainless screws or galvanized nails, and caulked at every joint to keep water from seeping through.

After the trim is replaced, you'll see straight, smooth boards with tight seams and no gaps where light or air can pass through. Paint will be even and free of bubbles or peeling, and water will bead up and run off instead of soaking into the wood. Drafts around windows and doors will stop, and the wall behind the trim will stay dry even during heavy rain.

We use primed pine or cellular PVC depending on where the trim is located and how much moisture exposure it gets. PVC costs more but doesn't rot, so it lasts longer in areas that stay damp or don't get much sun. We also handle fascia boards, corner trim, and rake boards along the roofline, which are common areas for water damage. If the trim is painted, we'll prime and coat the new pieces to match the existing finish as closely as possible.

You're Not Alone in Wondering About This

Most homeowners want to know why trim rots in the first place, how long repairs take, and whether the problem will come back. These answers address the practical concerns that come up before we start work.

What causes exterior trim to rot?
Rot happens when water sits on or soaks into bare or poorly sealed wood. This usually occurs around windows, doors, and rooflines where caulk has failed, paint has cracked, or flashing is missing or installed incorrectly.
How do you prevent trim from rotting again?
We seal every joint with paintable caulk, prime all exposed wood before installation, and make sure water drains away from the trim instead of pooling against it. PVC trim eliminates rot entirely in high-moisture areas.
What's the difference between wood and PVC trim?
Wood trim costs less and takes paint well, but it can rot if water gets in. PVC trim is waterproof and won't rot, warp, or split, but it expands and contracts more with temperature changes and requires specific fasteners and caulk.
How long does trim replacement take?
Most trim repairs in Barnhart take one to two days, depending on how many boards need replacement and whether we're fixing water damage underneath. Larger jobs like full fascia replacement take longer.
Can you match the trim color if I don't repaint the whole house?
We'll match the color as closely as possible using your existing paint or a sample you provide. New paint may look slightly different until it weathers, but the difference fades over a few months.
