Windows and sliding glass doors are some of the most vulnerable areas of your home’s exterior. At Allen Exterior Remodeling, Inc., Hillsboro's premier exterior repair contractor, we specialize in identifying moisture entry points, removing damaged materials, and rebuilding structurally sound, weather-resistant assemblies. Whether it’s trim, framing, sheathing, or sill plates, we restore your home’s exterior envelope to properly shed water and prevent future damage.

We work with quality products, proper flashing techniques, and proven waterproofing methods to ensure your windows and sliding doors can handle the Northwest’s toughest conditions.

Window & Door Dry Rot Repair

Dry rot around windows and sliding glass doors is more common than most homeowners realize. It often starts small—failed caulking, improper flashing, or water sitting against trim—and slowly spreads into the structural wood beneath. By the time it’s visible, there’s usually more damage hidden behind the surface.

We take a thorough approach to every repair:

• Remove all rotted wood, trim, and compromised materials
• Inspect underlying framing and sheathing for hidden damage
• Rebuild with new, treated wood where needed
• Install proper flashing and moisture barriers
• Seal and finish for long-term protection

Whether your sliding door sill is crumbling, your window trim is soft to the touch, or you’ve noticed staining and swelling, we can help. Our goal is to stop the damage at its source and restore the integrity of your home.

Water Intrusion & Leak Prevention

Water intrusion around windows and doors can lead to more than just rot—it can cause mold, insulation damage, and even structural issues if left untreated. In the Northwest climate, proper installation and sealing are critical.

Common causes we see include:

• Improper or missing flashing around windows and doors
• Failed caulking and sealants
• Poor drainage or siding integration
• Aging materials exposed to years of moisture

We don’t just repair the visible damage—we correct the underlying issue so it doesn’t come back. If needed, we’ll temporarily protect exposed areas and return to complete repairs when conditions allow.

Exterior Maintenance & Prevention

Regular maintenance is key to preventing dry rot around your windows and sliding glass doors. Keeping seals intact, ensuring proper drainage, and addressing small issues early can save you from major repairs down the line.

Our team can inspect your exterior and provide a detailed report with photos, helping you understand any problem areas before they worsen. We’ll give you straightforward recommendations and solutions tailored to your home.
