Of all the things that can shorten the life of a perfectly good chimney, water is the worst. Not only does water wreak havoc on masonry—the very substance your chimney is made of—but it is everywhere. Water comes in different forms all year round. When temperatures fall, water in the chimney is even worse. Fortunately for our customers with masonry chimneys, there is something we can do to prevent water damage during all seasons, and year after year.

Water and Your ChimneyWaterproofing Your Chimney Icon - Boston MA - Billy Sweet Chimney Sweep

Because of the materials that make up masonry, water is best avoided. The porous nature of masonry is perfect for venting your fires, allowing smoke, gas, and heat to release through the brick and mortar. This also allows water in through the masonry—unless it’s prevented. At Billy Sweet Chimney Sweep, we recommend preventing chimney leaks before damage occurs.
Your chimney leak can lead to:

  • Rusted parts and assemblies
  • Tilted/collapsed/settled chimney
  • Cracked/damaged flue liner
  • Deteriorated central heat
  • Clogged clean-out system
  • Rotting adjacent wood/wall coverings
  • Water stained bricks/walls

In addition to physical damage, your leaky chimney may also result in a drop in efficiency. A drop in efficiency means a rise in fire risk, putting your home and your family at risk.

Prevent Leaks From the Top Down

In order for your chimney to be truly waterproof, it must have all the necessary parts installed and in proper working order. The first thing we check when we get a call about a leaky chimney is the flashing. It is often improperly installed and a common point of water entry. The chimney must also have a chimney cap and crown to shed water from the top of the chimney.

Once all these components are in place, we can take it one step further by waterproofing the masonry itself. Our waterproofing agent is vapor-permeable which means the heat and gas produced by your fire will still be able to escape but water molecules will not be allowed in. This barrier penetrates deeply into the masonry so even cracks and gaps are protected from water penetration—and this protection lasts ten years!

When to Schedule Waterproofing

If you have never had your chimney masonry waterproofed or it has been more than a decade, it’s time to schedule this important appointment. Other water repellants and sealants from your local hardware store are not enough. In fact, most of them do more harm than good. Most sealants and repellants may keep water out, but also seal gases and moisture IN. This leads to a host of other problems. Let our team at Billy Sweet Chimney Sweep do the job, and get it right the first time.

We also install chimney caps, repair and install flashing, replace throat dampers with new, top-sealing dampers with an airtight seal, and repair and seal damaged crowns.

Don’t wait. Have your chimney waterproofed now, and you won’t have to worry about the water freezing in your masonry this winter. Worry about the rest of your summer, and leave the chimney up to us!
