The crown is the layer of cement sitting on top of the last row of brick and its purpose is to shed water away from the chimney. It’s normally 2 — 3 inches thick and starts high at the flue tile then slopes down to the edge of the bricks. Unfortunately, since cement is porous it allows water to penetrate and will eventually crack when the freezing weather begins. Failing chimney crowns are a common cause for chimney leaks that result in chimney repairs.

The first thing to do when tuck-pointing is to remove all loose joints then clean the surface thoroughly. Next, the new mortar, which contains a bonding agent is added to it to ensure a proper bond to the existing brick and mortar, is applied. Once the mortar is set, we strike it to give a nice finished look and then brush off any excess mortar for a clean finish We recommend waterproofing the newly re-pointed joints and surrounding areas 30 days after the completion of the job to allow the mortar to cure. Waterproofing the chimney will help prevent future repairs. All Pro Chimney Service offers a 3-year warranty our re-pointing work from disintegrating and cracking and a 3-year labor free warranty.

The chimney or firebox will be rebuilt to the original design unless the customer says otherwise.

Chimneysaver is applied to the chimney as a preventative means to protect the chimney or to help prevent further damages. Because the chimney is located on the outside of the house, it is vulnerable to the elements, porous and will eventually allow water into the house. Just like the crown, the chimney will allow water to penetrate and eventually after enough freeze and thaw cycles the bricks will begin to spall (when the faces of the bricks pop out) or the mortar joints will deteriorate leading to hundreds or thousands of dollars in repairs. The Chimneysaver waterproofing is applied to the chimney with a low-pressure sprayer. The waterproofing itself will soak into the brick and mortar about ¼’’ or deeper and is 100% permeable, which means it won’t trap water vapors that are trying to escape from the chimney while the chimney is in use. This is important because if the water vapors are trapped it can cause more water damage. All Pro Chimney Service strongly recommends waterproofing the chimney after any masonry repairs have been made to the exterior of the chimney. Chimneysaver offers a 10-year manufacturer’s warranty and All Pro Chimney Service offers a 3-year labor free warranty.
BRICK & STONE VENEERS
Using a brick or stone veneer is a great way to transform your fireplace, chimney, or interior and exterior walls of your home. They give the appearance of the natural brick or stone but won’t carry the same the cost. They can also be installed in areas where regular brick and stone can’t be because of size, weight, and support issues. All Pro Chimney Service offers a 3-year warranty on our installation of brick, cultured stone, or natural stone veneers from falling out or having cracked and disintegrating mortar joints and also offers a 3-year labor free warranty.
