With more than 18 years of experience we set the standard for industry best practices.

We begin the job from the ground up with the goal of solving problems and protecting your investment. Replacing old siding can significantly affect how your house looks – your siding covers most of the exterior of your home. Siding is also your primary protection against harsh weather and moisture. Aging, worn out siding not only show a home’s age but also allow moisture in creating an environment for dry-rot and mold growth.

Following our standards of excellence ensures certification for the manufacturer’s warranty for James Hardie and LP siding.

Each job is unique, but typically involves:

• Removing existing siding to expose problem areas. In some cases, it is necessary to resheet with plywood or CDX to maintain structural integrity and meet code.
• Protecting the house with premium house wrap. It is a breathable material that allows for interior moisture to wick out and exterior moisture to stay out, much like you skin.
• Using a starter strip to start the siding plumb and square.
• Proper trim installation with flashing and a top cap for siding that covers the side legs that extend to the bottom edge of the lower trim piece. This allows for moisture to sheet away and not leak in around windows and doors.
• Custom trim frames placed around all water and electrical utility devices on the exterior.
• Premium siding is then installed with a stagger pattern following the rule of 3 so there is an even dispersal of seams over the walls face.

Siding Replacement in Seattle

Seattle’s unique weather — from constant rainfall to salt air near Puget Sound — can take a toll on your home’s exterior. Over time, wood siding can warp, paint can peel, and fiber cement can crack if not installed or maintained properly. Replacing your siding isn’t just a cosmetic upgrade — it’s one of the most effective ways to protect your home from moisture, improve insulation, and increase resale value.

At MBA Exteriors, we understand the demands of Seattle’s Pacific Northwest climate, and we use only materials designed to perform year-round in damp conditions — from James Hardie fiber cement to LP SmartSide engineered wood.

The Importance of Moisture Protection

Seattle homeowners often deal with hidden moisture damage behind their old siding. If left untreated, trapped water can cause dry rot, mildew, and structural weakening. Our team doesn’t just cover up old problems — we fix them at the source.
Before any new siding goes up, we:

• Inspect and repair sheathing or framing damage.

• Apply a premium moisture barrier wrap for long-term protection.

• Use advanced flashing systems around windows, doors, and joints.

This process ensures your home stays dry, energy-efficient, and ready for decades of Northwest weather.
