Protect Your Chimney from the Pacific Northwest Weather

Rain, moisture, and freeze-thaw cycles are a chimney’s worst enemies — especially here in the Pacific Northwest. When water penetrates brick, mortar, or the chimney crown, it slowly breaks down the structure, leading to cracks, leaks, staining, and costly damage inside your home.

Bradley Chimney offers comprehensive waterproofing and repair services designed to seal, protect, and restore your chimney, keeping it safe, dry, and strong for years to come.

Why Chimney Waterproofing Matters

• Prevents costly water damage before it spreads
• Stops leaks that can ruin ceilings, walls, and framing
• Protects masonry from cracking, spalling, and deterioration
• Extends the lifespan of your brick chimney
• Reduces long-term repair costs by blocking moisture early
• Prepares your chimney to withstand harsh winter weather

Water is one of the leading causes of chimney failure — but it’s also one of the easiest problems to prevent with professional waterproofing.

🧠 FAQ — Chimney Waterproofing & Repairs

Q: How long does chimney waterproofing last?
Professional waterproofing typically lasts 8–10 years, depending on weather exposure and chimney condition.

Q: Can waterproofing stop an existing leak?
If the leak is caused by cracks, damaged flashing, or a failing crown, repairs must be completed before waterproofing. We handle both.

Q: Will waterproofing change the look of my chimney?
No. Our sealants are clear, breathable, and designed to preserve the natural appearance of your brick.

Q: What causes chimney leaks?
Common causes include cracked crowns, deteriorating mortar joints, poor flashing, porous brick, or missing chimney caps.

Q: Do all chimneys need waterproofing?
Yes — especially brick chimneys in wet climates. Waterproofing is one of the most cost-effective ways to prevent structural decline.
