When you have settling cracks in your brick walls, you need to get them repointed. This process is known as tuck pointing. However, before you make any attempts at repairing this yourself or hiring the repairs done by a Masonry in Nashville TN or handyman, you should know the top ten most common mistakes made in repointing mortar.
The first mistake is having the repairs made before checking for additional problems. Repairing the cracks in the mortar and brick before checking the foundation or other problems that occur can result in more damage to your home and to your Masonry in Nashville TN siding.
Settling cracks occur due to the foundation settling and applying stress to the bricks. This makes them a common symptom of foundation repair and can help in understanding where and how much movement of the foundation has occurred. Nashville Masonry
To tuck point the mortar and replace broken brick along these settling cracks limits the ability to accurately repair the house foundation. Performing these repairs often results in damage to the brick walls when the foundation is repaired. Any mortar or bricks placed in these cracks to fill the gap become a wedge and force the opposite crack to form in the area and the brick tend to push out at corners of the house causing brick walls to crack, lean away from the house, or come off the foundation entirely when the house is lifted.
It cannot be stressed enough to check for other problems with the structure or foundation of the home before repairing mortar cracks.
The second most common mistake made in fixing settling cracks in brick is choosing a foundation repair company to level your foundation. There is a difference between leveling your foundation of your house and fixing your foundation problems.
There has never been a house foundation built perfectly level that I am aware of, and to level the foundation under your house would apply stresses to your home and cause more problems with your foundation. This in turn would create more cracks in the bricks and mortar joints around your home. When they stress the word level and use a computerized level for their readings, it is a strong indication that they intend to try leveling your foundation even if it causes more problems. If they focus on lifting, stabilizing, adjusting, and use the cracks in the mortar and brick to acquire their range of movement in the house slab, then they are likely taking more accurate details about the movement and have a better chance at providing quality foundation repair services.
The third common mistake in brick repair is using these tubes of mortar repair caulking in an attempt to repair the cracks yourself. While caulking is used around doors and windows and in expansion control joints to seal the wall and still allow movement, they are not intended for use as the mortar and can cause other damage to the brick.
The caulking will never look like the mortar and tends to be difficult to clean off of the faces of bricks due to their texture. The same is true of many other Masonry in Nashville TN repair products. They contain adhesives, epoxy, and other add mixes that can be hard to work with and difficult to remove. It often requires removing all of the brick in areas where these products are used to repair the brick. If you want to repair the mortar cracks yourself, you should use a proper repointing mortar with the same composition as the original. These are not bulk items they are custom made for matching your mortar composition, and require a mortar matching analysis of your existing mortar samples.
The fourth masonry repair mistake is how you match the mortar. This is not to be confused with matching mortar color. Mortar matching is the process of analyzing samples of the mortar to identify their composition, performance, and formula. As the color of sand and other materials in the composition effect the color, they are related, but the base formula of a mortar composition must be matched before any attempts are made to match the color of an existing mortar.
