Chimney Waterproofing & Cap Services

Seal your chimney against leaks and weather with durable protection.

Protect your chimney from water damage, debris, and seasonal wear.

Chimney Waterproofing & Cap Installation

A leaking chimney allows rain, snow, and moisture into masonry, leading to cracks, mold, and interior damage. Waterproofing provides a breathable barrier that repels water while letting vapor escape—protecting your chimney from freeze-thaw cycles and long-term wear.

The chimney cap is the first line of defense, keeping out rain, animals, and debris. A properly installed cap paired with sealant ensures your flue stays dry and functional throughout the year—especially in areas around Chattanooga, Ringgold, and Dalton.

Our Waterproofing & Cap Services

Protect your chimney from water, debris, and long-term damage with expert waterproofing and cap installation.

Sealant Application

Protects masonry without trapping moisture. We apply a breathable sealant that repels rain and moisture. It prevents leaks, mortar erosion, and damage from extreme weather.

Chimney Cap Installation

Blocks water, animals, and debris.
We install custom-made stainless steel or copper caps that keep out rain, leaves, and birds. They also reduce downdrafts and fire risks.

Chase Cover Replacement

Caps and seals prefabricated chimneys.
We replace rusty or leaking caps with new, durable steel caps. They seal the top of the chimney to prevent leaks and protect the internal structure.

Design

Thorough evaluation for targeted protection. We begin by assessing your chimney’s masonry, flashing, and any existing caps or covers. This allows us to identify potential weak spots and plan for the most effective waterproofing solution.

Surface Preparation

Clean surfaces for long-lasting results. Before any installation or sealing, we clean the chimney crown, bricks, and surrounding areas to ensure proper adhesion of waterproofing materials and hardware.

Sealant & Cap Installation

Watertight protection, expertly applied. We apply a breathable waterproof sealant and install your new chimney cap or chase cover—ensuring a snug, weather-resistant fit tailored to your system.

Final Check & Walkthrough

Clean finish with full peace of mind. Once work is complete, we inspect for proper sealing, check for any leaks, and clean the site. Then we walk you through the results to confirm everything meets your expectations.

Why Chimney Waterproofing Is Essential

Humidity, storms, and seasonal shifts make waterproofing a must. In Tennessee, Georgia, and Alabama, chimneys face year-round exposure to moisture—from spring storms to winter freezes. Without proper waterproofing, brick and mortar can absorb water, leading to cracks, mold, and structural decay. Over time, this moisture accelerates the deterioration of masonry and creates pathways for leaks into your attic or living space.

Waterproofing your chimney isn’t just preventative—it’s protective. A high-quality sealant creates a breathable barrier that allows vapor to escape while repelling rain and humidity. At JDB, we ensure every chimney is sealed with long-lasting materials suited for the local climate.

The Difference Between a

Chimney Cap and a Chase Cover

A chimney cap is typically installed on masonry chimneys. It fits directly over the flue and is designed to keep out rain, animals, debris, and sparks. These caps are vital for preventing water damage inside the flue and blocking downdrafts that can affect heating efficiency or safety.

A chase cover, on the other hand, is used on prefabricated or factory-built chimneys with wood-framed enclosures. These flat, metal covers seal the top of the chase box and protect the entire chimney top from water intrusion. At JDB, we custom-fit both solutions based on your chimney type.

How Water Enters Your Chimney Without You Noticing

Hidden leaks cause visible damage—over time.

Small cracks in masonry, deteriorated mortar joints, or missing chimney caps may seem harmless at first. But over weeks and months, rainwater seeps in unnoticed. This water can soak insulation, damage interior walls, and even compromise the structural integrity of your chimney.

Because most damage starts internally, homeowners often don’t realize there’s a problem until it’s too late. That’s why we always recommend annual chimney inspections—especially in storm-prone areas like Chattanooga, Ringgold, and Cleveland.

Top Signs Your Chimney Needs a New Cap or Sealant

Don’t wait for a leak—know what to look for. Visible rust stains, musty odors, and white staining (efflorescence) on your chimney exterior are signs that water is getting in. You might also notice pieces of mortar falling off or dark streaks on your interior ceiling near the fireplace.

If your chimney cap is missing, damaged, or your sealant is peeling, it’s time for a professional inspection. These components are inexpensive compared to the damage water can cause if left unchecked. JDB can spot and solve these issues before they become expensive repairs.

Why Chimney Protection Adds Value to Your Home

Preserving structure today avoids big costs tomorrow. A chimney in poor condition is a red flag for home inspectors and buyers. Water-damaged masonry, mold, or signs of leaks can lower your home’s resale value or delay a sale altogether. Even more, unprotected chimneys are more likely to develop long-term problems that cost thousands to repair. On the flip side, a properly sealed and capped chimney shows pride in home maintenance. It ensures your fireplace system is safe, efficient, and ready for use year-round. JDB’s expert repairs and waterproofing keep your investment protected for years to come.

FAQ

Most frequent questions and answers

How often should a chimney be waterproofed?

Every 5–7 years, or sooner if you notice water seepage, brick discoloration, or efflorescence.

Can I use waterproofing without installing a cap?

Yes—but without a cap, debris and animals may still enter the flue. We always recommend pairing both for full protection.

What material is best for chimney caps?

We typically use stainless steel or copper for durability, corrosion resistance, and long-term performance.

Will waterproofing change the appearance of my chimney?

No. The sealants we use are clear and breathable, preserving the natural look of the masonry.

Do you serve my area for these services?

Yes—our service area includes Chattanooga, Cleveland, Ringgold, Dalton, and all communities within 90 miles.

Why is chimney waterproofing important?

Moisture is one of the leading causes of chimney deterioration. Applying a breathable, waterproof sealant helps prevent leaks, cracking, and mortar erosion—while still allowing trapped vapor to escape safely. It’s essential protection, especially in regions with heavy rain and humidity like Chattanooga and surrounding areas.
