Water is a Chimney’s No. 1 Worst Enemy

Chimneys are so susceptible to water damage because most all of them are made of brick, which is a porous material, and they are held together by mortar, which is water-soluble. To make matters worse, the inside of your chimney is made of metal, which will rust when exposed to water. Suffice to say that you need to keep water out of your chimney at all costs.

Speaking of costs, putting off repairing your leaking chimney may mean that your chimney and fireplace will end up requiring extensive masonry work. You may also find that you have to make repairs to your ceilings, mantels, walls, and flooring—and this kind of work doesn’t come cheap. Sure, you can take corrective measures after the water damage has occurred, but prevention will save you the most money.

Why You Need A Chimney Tech and Not a Roofer to Fix Your Leak

Unfortunately a fireplace or chimney that’s in disrepair may have numerous points where water is entering and causing damage. It’s not always easy to tell where a leak is originating, even though the damage it has caused may be widespread. A chimney technician from Pozzi Chimney Sweep will be able to inspect your chimney, use state-of-the-art technology like our ChimScan camera to pinpoint damage and the water’s point(s) of entry, and then suggest the proper steps to follow for waterproofing your chimney.

Please note that it can often appear that your roof is leaking when really it’s your chimney that’s leaking. For this reason, lots of homeowners mistakenly call a roofing company to fix a chimney leak, but roofers don’t know chimneys like chimney professionals do. They know roofs; we know chimneys. If you want to fix your chimney leak once and for all, call Pozzi Chimney Sweep.

How to Know If Your Chimney Is Leaking

Although a chimney leak isn’t always obvious, there are usually some telltale signs. You probably have a leaking chimney or water damage on your hands if you’ve noticed any of the following:

  • Rainwater in or around your fireplace or furnace thimble
  • Water damage to the walls or ceiling around your chimney
  • Deteriorated mortar joints and weakened masonry
  • A dripping noise

Let a certified chimney professional from Pozzi Chimney Sweep inspect your chimney to determine whether or not your chimney is leaking and to protect it from future water problems. Among other tried and true waterproofing techniques, we are proud to use Chimney Saver Water Repellent to keep water out of your chimney. Read more about our waterproofing process here.

My fireplace smelled strange, and because I knew I hadn’t had it cleaned in forever, I looked for a service online and Gary’s came up. He came out and inspected the firebox and said that I needed a new chase cover on the chimney. He ordered me a stainless steel one that he had fabricated somewhere and brought it out later and installed it and did a real nice job. He called me a number of times and kept me informed about what he was doing … I hired the right guy.
