Expert Post and Beam Replacement

Restoring Lasting Structural Integrity to Homes in Southwest WA

Does your home show signs of foundation failure or sagging floors? We specialize in the professional replacement of failing posts and beams to permanently restore strength and safety to your home.

The Problem

When Your Home’s Support System Fails

A post and beam foundation is created to raise your living area above the ground, forming the crawl space. While great for accessing utilities, the primary enemy of this system is moisture—especially in the damp climate of Southwest Washington.

Wood Rot

Posts constantly exposed to moisture become soft, crack, and lose their load-bearing ability.

Mold & Mildew

A damp space allows damaging growth of molds that negatively impact indoor air quality.

Pests

Rotting wood attracts termites and other wood-destroying insects, worsening the destruction.

Sagging

When posts decay, beams settle, causing uneven floors, sticking doors, and drywall cracks.

Whether you live in Battle Ground dealing with damp soil, or in Kelso fighting the effects of our relentless rain, failing posts and beams leave your home’s entire structure vulnerable.

Frequently Asked Questions

Common questions about Post and Beam Replacement in Southwest WA.

What’s the difference between post and beam vs. slab foundations?

Slab is based on concrete, and it is a slab foundation. A post and beam base makes your house rise with a crawl space having supports made of wood. This provides easy access to utilities, but the wood gets exposed to moisture and rot, particularly in SW Washington and therefore needs regular maintenance.

How can I tell if my posts and beams need replacing?

Look for rotting wood in your crawl space, musty odors, uneven or bouncy floors, sticking doors/windows, or cracks in your walls. Spot any of these? Schedule an inspection right away.

What does post and beam replacement cost?

The prices depend on the extent of damage, the size of the home, and the number of posts that will be required. This is why we provide a free and no obligation inspection with an in-depth quote based on your circumstances.

How long does the replacement take?

Most residential projects are completed in one to two days, thanks to our efficient process—minimizing disruption to your daily life.
