Everything You Need to Know About Exterior Trim Repair in the Pacific Northwest

Exterior trim refers to the boards and molding used to seal the gaps where different materials meet on your home’s exterior. This includes:

• Fascia Boards: The long, straight board that runs along the lower edge of your roofline, covering the ends of your roof rafters. It’s the board your gutters are typically attached to.
• Soffits: The exposed siding you see on the underside of your roof’s overhang. Soffits are crucial for attic ventilation, helping to prevent ice dams in the winter and reducing heat buildup in the summer.
• Window and Door Casings: The molding that surrounds your windows and doors, sealing the gap between the frame and the siding.
• Corner Boards: The vertical boards that cap the corners of your home where siding from two walls meets.
• Rake Boards: The trim that follows the pitch of a gable roof.

The primary job of all these pieces is to seal your home’s envelope. They block rain, wind, and pests from getting into the vulnerable seams and gaps of your home’s structure. When this seal is broken, your home becomes susceptible to the elements.

Common Signs Your Exterior Trim Needs Repair or Replacement

Catching trim problems early can save you thousands of dollars in future repairs. Grab a pair of binoculars and walk around your home, looking for these telltale signs of trouble:

Wood Rot and Soft Spots

This is the number one enemy of wood trim in our damp climate.

• How to Spot It: Use a screwdriver or even your finger to gently press on the trim, especially on corner joints and areas near the ground or roofline. If the wood feels soft, spongy, or crumbles easily, you have rot.
• What it Means: Rotting wood has lost all its structural integrity. It can no longer hold paint, and more importantly, it can’t keep water out.

Peeling, Cracking, or Bubbling Paint

Your trim’s paint is its first layer of defense.

• How to Spot It: Look for areas where the paint is flaking away, showing long vertical cracks, or appears to be bubbling up from the surface.
• What it Means: This is a clear sign that moisture has gotten underneath the paint layer. The wood beneath is likely saturated with water, creating the perfect conditions for rot to begin.

Gaps and Separation

• How to Spot It: Look at the seams where two pieces of trim meet, or where the trim meets the siding or roof. Do you see visible gaps?
• What it Means: As wood expands and contracts with temperature and moisture changes, joints can fail. These gaps are direct entry points for water, which can travel behind the trim and into your home’s sheathing and framing.

Visible Water Stains or Mold

• How to Spot It: Look for dark, discolored streaks on the trim or the siding directly below it. You may also see dark green or black spots of mold or mildew.
• What it Means: This is proof that water is consistently present where it shouldn’t be. This could be from a clogged gutter overflowing onto the fascia or a failed seal around a window.

Our Exterior Trim Repair Process: A Commitment to Quality

Simply patching over a problem or slapping a new coat of paint on rotting wood is not a real solution. Our repair process is meticulous and designed to provide a permanent fix that protects your home for the long term.

1. Thorough Inspection: We start by assessing the full extent of the damage. We don’t just look at the obvious rot; we investigate the source of the moisture to ensure the problem doesn’t immediately return.
2. Complete Removal of Damaged Material: All rotten or compromised wood is surgically removed. We cut back to clean, solid wood to ensure we have a sound structure to build upon. This is a critical step that many less experienced contractors skip.
3. Structural Assessment: If the rot has extended into the underlying sheathing or framing, we will assess that damage as well. We are fully equipped to handle structural repairs associated with trim failure.
4. Material Selection and Replacement: We replace the removed sections with high-quality, durable materials designed for the Pacific Northwest. We often recommend upgrading from standard pine to more robust options like cedar or modern composite materials.
5. Sealing and Finishing: The new trim is expertly installed, caulked with high-grade elastomeric sealants, and primed for painting. We ensure every seam and nail hole is perfectly sealed against the weather.
6. Priming and Painting: We finish the job with a high-quality exterior paint, providing the final layer of protection and a beautiful, seamless look that matches your home’s aesthetic.

From minor door trim repairs in Tacoma to extensive soffit and fascia projects in Kirkland or Bothell, our process ensures a repair that lasts.

Choosing the Right Materials for Your Trim Repair

The material you choose for your trim is just as important as the quality of the installation. We work with a variety of materials to suit your home’s style and your budget.

• Cedar and Redwood: These woods are naturally resistant to rot and insects due to their natural oils. They are a fantastic choice for the PNW and offer a classic, beautiful look.

• Engineered Wood: Products like LP SmartTrim are treated with preservatives to resist fungal decay and insects. They are dimensionally stable and come pre-primed for a superior paint finish.

• PVC/Composite Trim: Made from cellular PVC, this material is completely impervious to water and insects. It will not rot, split, or warp. It’s a higher-cost option but offers the ultimate in low-maintenance durability.

• Fiber Cement Trim: Brands like James Hardie offer trim that is fire-resistant, rot-proof, and holds paint exceptionally well. It’s an incredibly durable choice that perfectly complements fiber cement siding.

We can help you navigate these options and choose the best material for your specific needs and long-term goals.
