Waterproofing
Chimney Waterproofing in Nashville
Protect your chimney from Tennessee's rain and freeze-thaw cycles with professional waterproofing that lasts for years.
Water Is Your Chimney's Worst Enemy
Brick and mortar are porous materials — they absorb water with every rain. In Tennessee's climate, that moisture freezes and expands in winter, cracking mortar joints and spalling brick from the inside out. Over time, water intrusion causes deteriorating flue liners, rusted dampers, stained ceilings, and structural damage that can cost thousands to repair.
Nashville Chimney Pros applies ChimneySaver water repellent — the industry's leading vapor-permeable waterproofing formula — to create a breathable barrier that blocks liquid water while allowing trapped moisture to escape. A single application protects your chimney for up to 10 years and is backed by a manufacturer warranty.
Why Waterproof Your Chimney?
Stop Water Intrusion
Block rain and moisture from penetrating porous brick and mortar before it causes structural damage.
Prevent Freeze-Thaw Damage
Eliminate the freeze-thaw cycle that cracks mortar joints and spalls brick — the most common cause of chimney deterioration.
Protect Your Interior
Prevent water from migrating into your home through the chimney, causing stained ceilings, damaged walls, and mold growth.
10-Year Protection
ChimneySaver water repellent provides up to a decade of protection with a manufacturer warranty for lasting peace of mind.
Our Waterproofing Process
Inspection & Prep
We inspect the chimney for existing damage and make any necessary repairs before applying waterproofing — sealing over damaged masonry traps moisture inside.
Surface Cleaning
The chimney exterior is cleaned to remove dirt, efflorescence, and biological growth to ensure maximum adhesion of the waterproofing formula.
ChimneySaver Application
We apply two coats of ChimneySaver water repellent to all exposed masonry surfaces, ensuring complete and even coverage.
Crown Sealing
The chimney crown is treated with CrownCoat flexible sealant to fill hairline cracks and create a waterproof membrane over this critical water entry point.
