Waterproofing & Flashing Repairs
Masonry materials which are used in the construction of chimneys, are materials which are extremely porous by nature. What does this mean? Basically it means that the materials are going to absorb a large amount of water. The common brick which is used in the construction of chimneys is extremely spongy. It absorbs a high amount of water, which causes it to wick on the interior walls of the chimney in your home. If defective mortar joints are used in the construction, this will further the damage and absorption rates in your home’s chimney. The use of improper brick and mortar will greatly increase the potential that water absorption to the interior walls of the chimney will occur, which can potentially lead to a major problem for the homeowners dealing with this problem.
A series of products have been created for this specific problem. There are several waterproofing agents which can be used on the brick and mortar in order to help prevent this absorption or at least slow down the rate of absorption. Being 100% vapor permeable, the waterproofing agents allow the chimney to breath, so you do not have to worry about issues with build up either. What this does is to allow the water which has penetrated, along with the vapors produced as the chimney, to dry out and escape the chimney. The waterproofing agent which will be applied to the chimney is going to work on the outside. It will be used as a barrier to protect water from entering the chimney from the outside walls, and causing damage to the chimney’s interior and exterior. With most of these products that you purchase, you are going to find that a five to ten year warranty is included.
Sealers and paints should never be used as a waterproofing agent on your chimney, or other brick and mortar areas of the home for that matter. The reason is that the paint and sealers are going to trap the water vapors, along with moisture, inside the chimney’s walls. Over time this can lead to condensation build up, and it will eventually cause the chimney’s walls to deteriorate as time progresses. Further, it can cause mold and mildew on the interior walls of the chimney due to the sitting water in the home. This is going to cause an even bigger problem down the road, and will end up costing you far more than simply having to deal with the water damage caused by the interior chimney walls deteriorating.
Like any other area of your home, the chimney is one which you have to protect. Because it is around the roof, you have to take preventive measures to stop water, and other debris from getting in to the home. Using a waterproofing agent is one of the simplest, and most cost effective preventive measures which you can take as a homeowner who has a chimney in their home.
If you do notice there is already damage to the chimney (this can come in the form of chipping or cracking, gaps or voids, mortar damage, and so forth), it is important that these issues are dealt with prior to applying the waterproofing agent. All areas which are damaged, in any way, even if it is minor damage to the interior structure of the chimney, must be fully repaired in order to use the waterproofing agent, if you would like it to be effective in protecting the chimney from potential damage and harm in the future.
As far as the exterior of the chimney is concerned, it is also in your best interest to clean it, and remove debris, prior to applying any waterproofing agents to the chimney. If you notice damage, it is also important to treat the areas where you do see damage, prior to applying the waterproofing agents.
