Long-Lasting Chimney Waterproofing in Boston
Waterproofing is important for nearly every chimney, especially during the winter months when moisture levels are on the rise. If your chimney is musty or filled with water stains, let us waterproof it for you.
We Waterproof Chimneys to Protect Against Water Damage
As temperatures drop in Boston, water intrusion becomes common in residential and commercial chimneys. Water vapors get trapped in porous materials like concrete, brick, and mortar, causing continuous freeze thaw cycles. Eventually, small cracks begin to form in the chimney masonry, leading to a decrease in overall efficiency and deterioration of the bricks.
At Bob’s Chimney, we provide chimney waterproofing services that make your chimney water-resistant while still maintaining a natural appearance. We use high-quality sealing products developed specifically for chimneys, protecting the bricks from water vapors while allowing sufficient ventilation at the same time. In just one thorough application, we protect your masonry with a durable water-resistant coating that lasts for a long time.

Busting Common Myths About Chimney Waterproofing
People have several misconceptions about chimney waterproofing. The most common of these is the assumption that masonry does not need to be waterproofed because it’s durable. While that is true, masonry is highly porous as well, which means that moisture would naturally enter and stay trapped in the bricks. Waterproofing helps to prevent this risk.
Another misconception is that using paint over the masonry is enough to seal it. The truth is that most generic paints trap water vapors instead of letting them escape. This is why it’s important to coat bricks with a vapor permeable water repellent instead of a random sealant.
Some homeowners also believe that it’s not important to waterproof chimneys unless there’s any visible damage, but by then, it’s already too late. We recommend waterproofing your chimney regularly, especially when it is still in good condition.

Signs You May Need Chimney Waterproofing in Boston, MA
01
Water Penetration
When water enters the chimney, it leaves behind water stains on the masonry. It also reduces the efficiency of fireplaces or stoves.
02
Spalling Brickwork
When bricks absorb too much moisture, they start ‘spalling’, which refers to bricks shifting from their original position or even falling off.
03
Discoloration
White powdery residue on the chimney is often a sign of efflorescence. You may notice salt deposits forming on the surface of bricks and mortar.
04
Moldy Smells
Excessive moisture intrusion often leads to moldy or rotten smells inside the fireplace or the chimney. This can also cause health problems.
05
Rust on Firebox
Water damage doesn’t remain localized. It spreads to other parts of the chimney as well. You may notice rust and corrosion on the firebox.
06
Missing Chimney Cap / Crown
A missing chimney cap or crown leaves your chimney vulnerable to water intrusion, dirt buildup, and animal infestation.
How to Maintain Your Waterproofed Chimney in Good Condition?
After waterproofing your chimney, the next step should be to focus on maintenance. The Chimney Safety Institute recommends regular inspections of the chimney, followed by cleaning to prevent any hazards. It’s important to get an annual chimney inspection by a professional like Bob’s Chimney to check whether the flue, crown, flashing, masonry, or other components are free from moisture buildup.
Since waterproofing is not a one-time treatment, you may require reapplications based on how often you use your fireplace. If it’s been 7-10 years since you last got your chimney waterproofed, it’s best to schedule waterproofing services again. Finally, don’t forget to remove vegetation or algae growth near the chimney base.
Our Process for Chimney Waterproofing in Boston, MA
STEP 01
Chimney Inspection : We create a personalized chimney waterproofing plan based on your chimney’s condition. We first perform an inspection of the roof line, masonry, and brickwork.
STEP 02
Chimney Sweeping : Before sealing the chimney, we have to ensure the surface is completely dry and clean. We remove moisture and clean any dirt, contaminants, and debris lying inside.
STEP 03
Using Joint Sealants : Small cracks in the masonry are addressed using paintable caulk, while the mortar joints are filled using joint sealants. This helps to create an even structure prior to sealant application.
STEP 04
Applying Water Repellent : We use vapor permeable water repellents to seal your masonry or brick chimney. This helps maintain airflow while repelling excess moisture from infiltrating the chimney.
STEP 05
Replacing Chimney Cap : The chimney cap sits at the top of the opening, preventing water from entering the flue. If your chimney cap is damaged, we’re here to replace it with a brand new one.
STEP 06
Repairing Chimney Crown : The chimney crown, usually made of concrete, stone, or stainless steel, covers the entire top of the chimney. If it’s cracked, chipped, or unevenly installed, we fix it fast.
STEP 07
Repairing Chimney Flashing : The flashing forms a watertight seal at the area where the roof meets the chimney. We replace damaged flashing to prevent water from damaging the roofing materials.
