Window trim is a structural and aesthetic element that finishes the space where your window meets the wall. On the exterior, it deflects moisture, seals against drafts, and frames the unit for weather resistance. Inside, it hides seams, protects drywall corners, and gives the window a polished look. Trim includes the casing, sill, apron, and optional decorative molding. Materials can range from engineered wood and PVC to vinyl and MDF, each offering different levels of moisture resistance and paint adhesion. Correct trim selection improves both performance and appearance.
Trim installation begins with proper measurements and material prep. For interiors, components like sills, head casings, side casings, and apron moldings are cut and attached using finish nails or adhesive. Joints are mitered or coped for a clean fit. Exterior trim requires weatherproofing strategies such as flashing tape, drip edges, and sealed joints. Casing is placed to create visual balance and protect against water intrusion. Trim is caulked and sanded, then finished with paint or stain. The process demands accuracy to ensure tight seams and lasting structure.
Trim isn’t just visual—it protects structural gaps and seals the frame-to-wall transition. We work with a range of materials, including engineered wood, PVC, and vinyl trim, selected for moisture resistance, paintability, and durability. Every cut is measured for tight joins, and mitered corners are sealed to prevent water intrusion. For exterior projects, we integrate flashing and back-caulking. On interiors, smooth molding profiles are installed to blend seamlessly with your home’s style. The result is trim work that’s both protective and polished, built to last in any setting.
Window trim plays a defining role in how your windows look and perform. Choose from traditional colonial, craftsman, modern flat-stock, or rustic distressed styles to suit your space. Materials include primed wood, vinyl, and PVC, with options for pre-finished surfaces or custom paint. Wide casings provide a bold architectural effect, while narrow trim fits minimalist design schemes. Matching baseboards and crown molding can tie the look together. Moisture resistance and UV stability are critical for exterior applications, especially when selecting exterior wood trim for windows.
Keeping your window trim in top shape doesn’t require much—just consistency and attention. Wipe down interior trim regularly with a dry cloth or damp sponge to remove dust and debris. For exterior trim, repaint or touch up surfaces every three to five years to shield against weather exposure. Inspect caulking at least once a year and reapply where cracks or shrinkage appear. If mildew forms, clean it using a solution of diluted vinegar. Avoid using high-pressure washers on wood trim, as they can cause splintering or moisture intrusion. Make sure your downspouts direct water away from window edges to prevent saturation. Promptly touch up scratches in painted finishes to keep moisture out, and replace any damaged trim pieces before issues spread further. These simple steps can extend the life and performance of both your interior and exterior trim.
