Chimney Waterproofing: Protecting Your Masonry from the Elements

Your chimney stands tall against everything nature throws at it - rain, snow, ice, and heat. But over time, these elements take their toll.
Brick and mortar are porous materials, which means they naturally absorb water. That moisture can freeze, expand, and cause cracks, leaks, and deterioration from the inside out.

That’s why chimney waterproofing is one of the most effective ways to preserve your chimney and prevent costly damage.

Professional Chimney Waterproofing Services

Our professional team uses high-quality, vapor-permeable sealants specifically designed for chimney masonry.
These products repel water while still allowing the bricks to “breathe” - meaning any trapped moisture inside can safely escape, preventing pressure buildup or damage.

Our waterproofing process includes:

A full inspection of your chimney and masonry.

Cleaning and prep to remove dirt, soot, and old coatings.

Applying a professional-grade waterproof sealant with full coverage on all exposed brick and mortar.

Checking and sealing critical points like flashing, crown, and joints for total protection.

We only use top-rated, industry-approved materials that last for years - not temporary hardware store sprays that fade in a season.

Why Chimneys Need Waterproofing

Even a well-built masonry chimney is vulnerable to water. Over the years, tiny cracks form in the bricks and mortar joints. When water seeps in and freezes, it expands - slowly breaking the masonry apart.

Without waterproofing, this can lead to:

Cracked or spalling bricks

Leaky fireplaces and walls

Stained or crumbling mortar joints

Rusting of metal components inside the chimney

Mold and interior water damage

Water is the number one cause of chimney deterioration. The good news? It’s completely preventable.

When to Waterproof Your Chimney

If your chimney is newer or has recently been tuckpointed, repaired, or rebuilt, waterproofing is the next essential step.
For older chimneys, waterproofing can help stop further water absorption and slow down deterioration.

We recommend reapplying professional waterproofing every 5–10 years, depending on your chimney’s exposure and condition.
