DIY Trim Maintenance Tips from the Pros

Trim and molding are the finishing details that bring character, warmth, and polish to your home. Whether it’s crown molding, baseboards, or window casings, these elements frame your space and elevate every room’s design. But over time, daily wear, humidity, and house settling can cause cracking, scuffing, or separation.

At Custom Carpentry of Nashville, we specialize in creating and restoring beautiful trim work throughout Middle Tennessee homes. Today, we’re sharing our pro-approved DIY trim maintenance tips to help you protect your investment and keep your home looking its best.

1. Regularly Inspect Your Trim and Molding

Every few months, take a slow walk around your home and look closely at your trim. Pay attention to:

• Gaps between trim and walls or floors
• Cracked or peeling paint
• Nail holes or minor dents
• Moisture or warping, especially in bathrooms and kitchens

Spotting these early helps you prevent bigger repairs down the road.

2. Keep It Clean

Dust, scuffs, and grime can dull your trim’s finish over time. To clean it properly:

• Use a soft microfiber cloth or a duster weekly.
• For deeper cleaning, mix warm water with mild dish soap and gently wipe the surface.
• Avoid harsh chemicals or too much water, which can damage wood and paint.

A quick monthly cleaning keeps your trim bright and prevents long-term discoloration.

3. Repair Small Dents and Cracks Early

Minor imperfections are easy to fix if you catch them early.

• Use wood filler or caulk for small nail holes or separation at joints.
• After drying, lightly sand the area smooth before repainting.
• For deeper damage or warped sections, replace the affected trim piece to maintain a seamless look.

These small DIY repairs keep your interior looking freshly finished.

4. Refresh Paint or Stain When Needed

Painted and stained trim will naturally fade or chip over time. A quick refresh can make your entire space look new again.

• Painted trim: Sand lightly, clean the surface, then apply a high-quality interior paint with a semi-gloss finish for durability.
• Stained trim: Lightly sand and apply a fresh coat of stain or polyurethane to restore shine and protection.

Pro tip: Always color-match your existing finish or take a small piece to your local paint store for help.

5. Protect Trim from Moisture

In humid Nashville weather, moisture can cause wood trim to swell, warp, or separate from walls.

• Keep a stable indoor humidity level between 35% and 55% using a dehumidifier when needed.
• Wipe away spills immediately to prevent staining or swelling.
• Ensure bathroom and kitchen ventilation fans are working properly.

Controlling humidity is one of the simplest ways to preserve your home’s craftsmanship.

6. Caulk for a Polished, Sealed Look

Over time, caulk between trim and walls can dry out and crack, leaving visible gaps. Re-caulking not only improves the appearance but also seals out moisture and drafts.

• Use a paintable latex caulk.
• Apply a thin, even bead along gaps, then smooth it with a damp finger or caulk tool.
• Let it dry completely before painting.

Fresh caulk instantly sharpens the lines of your trim and gives your room a finished look.

7. Handle Baseboard Scuffs Quickly

Baseboards take the most abuse — from vacuums, furniture, and pets. To keep them looking new:

• Use a damp cloth or magic eraser for marks and scuffs.
• Touch up with matching paint for deeper scratches.
• Add clear corner guards in high-traffic areas if damage happens frequently.

A little touch-up goes a long way toward keeping your trim crisp and clean.
