Chimney Waterproofing | Protect Your Chimney From Rain & Snow

Chimney Water Repellent Protection

It is actually not good to "waterproof" your chimney. We use a product called ChimneySaver Water-Base Water Repellent to help defer the effects of water on your masonry.

Whether you live in a mid-19th century row house in Columbia Heights, DC, or a modern suburban home in Montgomery County, MD, or Northern Virginia, your brick-and-mortar chimneys are prone to water damage. Over time, bricks lose their hard outer shell, allowing water to enter the porous material, absorbing moisture like a sponge. Eventually, the masonry cracks, flakes, crumbles, and even falls off the chimney. As the masonry damage progresses, the chimney becomes a fire hazard, making it unsafe to light your fireplace or stove.

Bethesda Chimney’s certified chimney professionals provide expert chimney sealing, brick replacement, tuckpointing/repointing, and other quality masonry services for homes, businesses, and government buildings in Montgomery County, MD, Northern Virginia, and Greater Washington, DC communities.

Why Chimney Sealing is Necessary

Water is your chimney’s number one enemy! Our wet and cold winter weather and hot and humid summers accelerate masonry deterioration. Water not only damages the exterior brick and mortar, but when it seeps through masonry cracks or gaps, it can cause widespread damage to the chimney's interior too. Sealing your chimney is an easy and inexpensive solution for protecting your chimney from costly repairs due to water damage. It will also prolong the useful life of several significant components, including the flue liner, interior masonry, damper, and firebox.

Chimney sealing Benefits

Bethesda Chimney’s waterproofing solution offers numerous money-saving benefits, such as:

  • A full ten-year warranty and performance guarantee.
  • Repels rain, snow, and ice.
  • A 100 percent vapor-permeable membrane allows the masonry to “breathe” so it won’t trap moisture.
  • Water-based formula that meets VOC compliance regulations.
  • Prevents white staining due to moisture absorption.
  • Non-Glossy look.

Our Water Repellant Is Formulated to Preserve Masonry Chimneys

When sealing your chimney, not any solution will do. This is not a job that we recommend you do yourself.

Without sealing you may see more damage to the chimney. Water sealants without a vapor-permeable membrane trap moisture inside the bricks, which will continue to damage the masonry.

Our chimney waterproofing solution is applied by a Certified Chimney Professional® and comes with a 10-year performance warranty. It is a quick and inexpensive solution that will provide a decade of protection, saving you thousands in repairs.
