Waterproofing Services

Because the most expensive tile problem is the one hiding behind the wall.

Most tile contractors treat waterproofing as a box to check. Bill Finney Tile treats it as the foundation of everything else. In 45 years of working on bathrooms, showers, and wet areas across Battle Ground and Southwest Washington, the most common problems we see — cracked tile, crumbling grout, mold behind the wall — trace back to one thing: the waterproofing was skipped, rushed, or done wrong from the start. Your home deserves better than that, and so do you.

Waterproofing is not a single product you roll on and forget. It is a system — liner selection, membrane application, curb preparation, drain integration, and surface compatibility — and every component has to work together. Bill Finney Tile handles shower pan waterproofing, wet wall membranes, cement board systems, and full moisture barrier installation for bathrooms, laundry rooms, and any area where water is a daily factor. Whether you are starting a new build or replacing a failed system in an older shower, the approach is the same: do it right the first time.

You should not have to wonder whether your shower is going to hold up in two years. When Bill Finney Tile completes the waterproofing on your project, you will know exactly what was installed, how it was done, and why it will last. If you are in Battle Ground, Vancouver, Camas, or anywhere in Clark County and you want a tile contractor who takes this step seriously, you are in the right place. Call (855) 922-2636 and let's talk through your project.

What We Offer:

Shower Pan Waterproofing – Full pan liner and membrane installation designed to contain water at the base of your shower before it ever reaches the subfloor.
Wet Wall Membrane Systems – Industry-grade membrane application on shower walls and wet areas to stop moisture from penetrating into the wall cavity.
Cement Board Installation – Proper cement board and backer installation as a stable, moisture-resistant substrate before any tile goes up.
Drain Integration & Sloping – Correct slope and drain seating so water moves toward the drain the way it is supposed to — every time.
Laundry Room & Wet Area Waterproofing – Moisture barrier installation for laundry rooms, mudrooms, and other high-humidity spaces that take daily water exposure.
Pre-Tile Moisture Assessment – Before installation begins, we assess the existing surface for signs of prior moisture damage and address any issues before they become your problem later.
