For West Seattle homes, exposed to relentless Pacific Northwest rains, brick and mortar are inherently porous. Every rainfall drives water deep into the masonry, where our local winters cause it to freeze, expand, and inevitably crack your chimney apart—a destructive process known as spalling. Our vapor-permeable waterproofing sealant acts as an invisible shield, effectively stopping water penetration while still allowing the masonry to 'breathe' and release trapped moisture. It's a fast, inexpensive, and highly effective way to safeguard a sound chimney in West Seattle for many years.
In West Seattle's perpetually damp climate, especially for homes near Puget Sound, waterproofing is exceptionally valuable. The constant moisture exposure makes preventing water intrusion a critical long-term protection strategy.

What's included
Brick is a porous material. Without a protective seal, every West Seattle rain drives water deep into the masonry, where it freezes and initiates the destructive process of spalling.
How it works
We clean the masonry and pre-treat any small cracks or joints.
A breathable sealant is applied over the full chimney exterior.
The masonry repels water but still releases trapped moisture.
Photos document full, even coverage.

Why it matters
Brick and mortar, by their very nature, are designed to be porous. This means every rainstorm that sweeps across West Seattle drives water deep into your chimney's masonry. During our Pacific Northwest winters, this absorbed water freezes, expands, and relentlessly cracks the surface apart—this is the insidious freeze-thaw cycle responsible for most spalling. A vapor-permeable water repellent is a crucial defense: it prevents rainwater from soaking in while still allowing any existing trapped moisture within the masonry to escape. This proactive treatment protects your sound masonry for years, halting the season-by-season deterioration.
If any of these sound familiar, it's worth a free inspection:
See the difference
The before is porous, water-stained brick that soaks up rain like a sponge; the after is sealed with a breathable, vapor-permeable masonry repellent. The right product blocks liquid water from entering while still letting trapped moisture escape — so the brick doesn't trap water and crack apart in a freeze. It's a low-cost step that extends the life of sound masonry.
Thirsty, water-stained brick treated with a breathable repellent that lets it dry out.
Representative example of a typical chimney waterproofing — not a specific customer job. We add photos of our own completed West Seattle projects as we finish them.
A representative scenario: a brick chimney on a view home along the Admiral ridge, where the masonry stays damp for weeks and the weather face has begun to flake after a few rough winters. Porous brick drinking wind-driven rain and then catching a freeze is exactly how spalling starts on this peninsula. Once the masonry checks out sound, we would apply a breathable water repellent that turns away liquid water but still lets the brick dry through. The result is masonry that sheds the rain and holds up to the next cold snap.
