Is Your Chimney Leaking?

Have you noticed noticed peeling wallpaper or water stains on the walls or ceiling? If so, you most likely have a leaky chimney. Signs of a chimney leak also include: standing water in the firebox, a musty odor, and damaged or missing bricks and mortar joints on the exterior chimney. It is important to take care of this type of problem as soon as possible. If you don’t, you could end up with extensive and expensive chimney damage!

Is Your Chimney Leaking Image - Chicago IL - Aelite Chimney SpecialtiesAs the Chimney Safety Institute of America (CSIA) warns, water is the biggest enemy of masonry chimneys. When you see any signs of a chimney leak, give us a call at Aelite Chimney Specialties. Schedule an appointment with one of our CSIA-certified chimney technicians. You can count on us to give you a fair and honest estimate with evidence of any damage that is causing the leak. In addition, an explanation of how we will repair that damage to fix the leak. We would like to tell you more about a couple of the most causes of chimney leaks.


Not having a customized flashing system to protect the most vulnerable spot for leaks, where the chimney meets the roof, is one of the most common causes for chimney leaks. Even if you have flashing installed on your roof and chimney, it may not be doing its job if it has not been properly constructed. Over our years of working on chimneys in the Chicago area, Aelite Chimney Specialties has seen how poorly built flashing can even cause chimney leaks. We take great care when measuring your chimney. Aelite can cut metal sheeting in the right sizes to protect your home from water leaks. We also make sure that all of the corners have been caulked to keep water from entering in those areas.


Since your chimney crown sits on the top of your chimney, it is directly exposed to all of the water from rain and melted ice and snow. Your crown is made from mortar that can withstand this type of exposure. However, it can still develop cracks and other types of erosion damage over time. If your crown is cracked and damaged, water can easily get into your chimney. One of the first places Aelite Chimney Specialties will look for the source of a chimney leak is the crown. If we find cracks in your chimney crown, we can repair them. If your crown is damaged beyond repair, we can construct a new one that will protect your chimney from water penetration for years.

5 Most Common Chimney Repairs

Knowing what the common chimney repairs are can help homeowners be more mindful of the care their chimney should have in order to prevent such damages.

In Northern Illinois no one wants to be caught in the fall without a chimney or fireplace that’s anything other than ready to fire up. That’s why we suggest tackling chimney maintenance and any needed chimney repairs during the spring or summer months. If you take care of it now, you won’t have to wait to get an appointment with a chimney technician in the fall.

Outside of chimney sweepings and inspections, the team members at Aelite Chimney Specialties are tasked most often with chimney repairs. Father Time and Mother Nature are to blame for many of the things that go wrong with chimneys, though poor installations and faulty connections can certainly cause problems, too. We recommend that you use a CSIA certified chimney technician to handle chimney installation and maintenance work. Besides safety concerns, a chimney that is connected and serviced properly will perform more efficiently.

Most of the chimney repairs we undertake are in the interest of keeping water out of the chimney and preventing chimney fires. Here are five of the issues we find most often:

1. Loose or Rusted Flashing

The No. 1 cause of leaky chimneys is loose flashing. Flashing is the band of sheet metal that is woven together around the chimney where the chimney meets the roof. Read about why flashing leaks here.

2. Cracked Tile Chimney Liners

Your chimney liner runs the length of your chimney flue, protecting your chimney from heat transfer and creating a smooth tunnel through which smoke and toxic gases can safely vent. Liners can be made out of stainless steel and ceramic tile. Most older liners are made of tile, which tends to crack over time. Luckily, tile liners can usually be repaired with a product called HeatShield, which we use often with great success. Read about our relining services here.

3. Cracked Chimney Crowns

A chimney crown is designed to slope downward to direct water away from the chimney flue and on to the roof. (The flue liner is allowed to project above the crown, and should be protected by a chimney cap or damper.) Over time, crowns can crack or decay. An Aelite Chimney Specialties technician will be able to repair or replace your crown.

4. Damaged Chimney Caps or Chimney Dampers

These two chimney parts serve similar purposes—keeping water, debris, and small animals out of your chimney, though the damper takes its usefulness one step further and also helps you save energy dollars, as you can completely close it when your chimney is not in use. If your chimney cap or damper is broken, leaking, or inefficient, a professional can determine whether it needs to be replaced or just repaired.

5. Masonry Repairs

If your chimney masonry has never been waterproofed, we are willing to bet that it has seen better days. Read about what goes wrong with masonry and how we can fix it and shore it up against future damage.

Spring time is the right time to address your chimney’s problems. Call Aelite Chimney Specialties today to schedule an assessment with one of our CSIA certified technicians.
