WHY WATERPROOF YOUR CHIMNEY?
Moisture is your chimney's worst enemies. With the amount of rainfall we get in northeast Tennessee, the brick seldom gets completely dry before it is hit by another rainstorm. The constant assault by water can cause your chimney to deteriorate right before your eyes. Brick is a porous material held together by mortar, both of which are highly susceptible to water caused deterioration. In addition, the warm moist air flowing from inside the home and up the flue creates condensate from the inside out.
Some common signs of water damage are:
. white streaks (efflorescence) layers flaking off the brick (spalling) cracks that get larger each year, water dripping into your firebox, brown stains showing on your ceiling near the fireplace, sections of brick always looking wet or darker than the rest, and loose or damaged flashing.
If you notice any of these signs contact us IMMEDIATELY. Failure to address these moisture problems can lead to thousands of dollars in damage.
We will conduct a thorough inspection of your chimney and give you a written detailed proposal to fix all the problems and provide preventive measure to stop future additional damage. As always, our technicians are licensed and insured.

If you are like most homeowners, your chimney is not something you think about until you have a problem. Because chimneys project above the roof line, they are exposed to more severe weather than any other part of your home. Spending a little time to protect your chimney now may save you thousands of dollars down the road after more serious damage occurs.
Chimneys take a beating from severe weather year round. Water penetration is the single biggest cause of deterioration and damage. Waterproofing your chimney is a simple and easy task that will extend the life of your chimney for years and protect against expensive repairs. Chimney leaks are a frustrating problem for many homeowners. Waterproofing your chimney is the best way to solve chimney leaking problems. While there are several potential sources of water intrusion on a chimney, the brick and mortar joints is usually the most obvious place to start. In the picture to the left, notice how there are areas of dark brick on either side of a lighter area. The darker areas are showing signs of water intrusion. Left untreated the brick will suffer significant damage. Don't wait- Let us make these repairs before the damage gets out of hand Call us at 423-398-1632 . |
Water is constantly trying to make it's way into your chimney. When it does, your chimney begins to slowly but steadily deteriorate. Given enough time, the chimney can be reduced to a useless pile of rubble.
It is important that you monitor your chimney looking for signs of water intrusion. Better yet, have a Chimney Professional inspect your chimney system annually as part of an annual cleaning and inspection maintenance program.
When conducting an inspection, the technicians from Chimney Sweeps will look at 5 main areas for signs of water intrusion.
1. Rain Cap- All flues should have a good quality rain can installed. Without it, every time it rains large amounts of water goes straight down the flue. This is the first and easiest point of entry to control. We keep all sizes of rain caps in stock and can easily install one for you
2. Cracked Crown - The crown is the horizontal surface at the top of the Chimney Chase. The crown is made of either concrete, mortar or it could be a metal chase cover. Concrete and mortar crowns often crack over time. Chase covers are often made from galvanized steel and galvanized WILL rust. Any of these failures will allow water into the chase resulting in damage.
Our technicians will offer you three different options to repair your crown. If the masonry crown only has minor cracks, an elastomeric rubber coating may be a sensible option. A better and more permanent option is to either pour a new Concrete Crown or install a new metal Chase Cover. A proper crown will not only cover the horizontal surface but also come down over the side a minimum of 3 inches. This assures that water will drop down rather than try to run back under the crown. When we install a new masonry crown we use High Strength Concrete not Mortar. Concrete lasts longer. We fortify the concrete mix with water repellents. If a metal chase cover is the right choice for you, we will have it made at a local metal shop and will recommend it be made from either Aluminum or Stainless Steel. Copper is another good choice for an upscale look.
3. Brick Work - Bricks and mortar can absorb water to the point that the mortar will soften and the bricks will develop a condition called Spalling. Spalling occurs when the outer layers of the brick flake off. Each time a layer flakes off, more moisture is absorbed and another layer will flake off eating away at the brick until there is nothing left. Other signs of water absorption are white flaky deposits called effervescence. You may also see dark and light areas in sections of the brick. The drark areas are probably areas that are absorbing water. We recommend applying a water repellent to the chimney Chase. Not a sealer but a repellent. The brick needs to breathe. A repellent will allow this but a sealer will trap moisture.
4. Flashing - Flashing is metal placed where the shingles meet the chimney and serve as a seal between the two. Improperly installed flashing allows rain water to enter your home damaging the interior brick and possibly the ceiling in your home.
We can install a product called flash seal which is a rubberized material embedded into a fiberglass cloth. This forms a near permanent bond to the chimney and roof surface keeping rain water out of this junction point
5. Ventilation - As mentioned earlier, bricks need to breath. If your chimney does not have any vents near the bottom we can install a series of small vents. This will allow air movement within the hollow chimney chase giving the bricks a chance to dry out.

Crown Damage The Crown is the horizontal surface at the top of the chimney chase. It is usually made of either concrete or mortar. It is quite common for the crown to crack and deteriorate over time. The cracks can allow large amounts of water to enter the chase causing further damage to the brickwork of your chimney
"SPALLING" occurs when the brick deteriorates to the point that the out layers of the brick fall off. We can't replace what has already fallen off but we can keep it from getting worse.
