Stop Water. Save Your Chimney.
Chimney Waterproofing & Flashing Repair – Natick, MA
The Hidden Enemy Above Your Roofline
Water is the number one cause of chimney damage in New England. Each year, rain, snow, and ice penetrate porous masonry, expanding and contracting with every temperature change.
Over time, this leads to:
- Cracked mortar joints
- Leaking ceilings and stained walls
- Flaking brick surfaces
- Rusted fireplace components
At Chimney Goat – Natick, we specialize in chimney waterproofing and flashing repair designed for Massachusetts’ harsh climate. Our goal: protect your chimney structure, your home interior, and your investment — for decades to come.
Why Flashing Fails
Our Waterproofing Process
Step 1 - Inspection
We examine the crown, flashing, mortar joints, and chimney cap for cracks, gaps, and signs of water intrusion.
Step 2 - Surface Cleaning
We clean all surfaces using safe, high-pressure air and brushes to remove dirt, efflorescence, and biological growth.
Step 3 - Masonry Sealing
A vapor-permeable waterproofing agent is applied — allowing the brick to breathe while locking out moisture.
Step 4 - Flashing Reinforcement
We inspect and reseal or replace flashing using high-grade copper or aluminum sheets sealed with elastomeric coatings.
Step 5 - Crown Protection
We apply a flexible, water-resistant crown coating that expands and contracts with temperature changes — preventing future cracks.
Why Flashing Fails
Flashing is a thin metal barrier that keeps water from seeping where the chimney meets the roof. But even small gaps in flashing can cause thousands of dollars in damage.
Flashing typically fails due to:
- Weather expansion and contraction
- Rust or corrosion
- Improper installation
- Deterioration of old sealants
We replace and seal flashing using premium copper or aluminum, ensuring long-term resistance against leaks and rust.
