Chimney Crowns

Most chimney crowns are nothing more than a thin layer of mortar spread over the top of a masonry chimney that tapers down to the outside edges. Because they are so thin and lack either reinforcement or expansion joints, they typically start to break up after only a few years.

Once water gets between the flue and the chimney surface, problems follow quickly. If the water freezes, it can pop the hard-fired surfaces off the bricks. Spalled brick not only looks bad, it also allows even more water to penetrate the porous surface. A chimney crown should be made with reinforced concrete that is at least 2 in. thick at its thinnest point. It should be arched slightly to shed water.

Pointing/Grind and Point/Tuck Pointing

Tuck-pointing can be defined as the removal and replacement of mortar between stone, block, or brick. Brothers Services masonry crews will replace the existing failing mortar with new mortar to match the original masonry texture and color as closely as possible. Once mortar has been placed within the joint, it is then tooled. When done properly, tuck-pointing will provide a strong, water-resistant joint that will extend the life of your masonry chimney and prevent future brick chimney repair needs.  This can save you money and really is not just a patch but also a quality job.

Referred to as tuck-pointing, pointing, re-pointing, spot pointing, & brick chimney repair.  Tuck pointing restores the masonry mortar or chimney mortar joints between your bricks to eliminate water intrusion, prevent structural compromise, and restores the integrity & aesthetic value of your chimney. It is important to seal the brick chimney after you point it.

Deteriorated brickwork weakens the chimneys integrity and allows cold drafts, water, and insects to invade your home. Many times this is caused by a bad flue liner that allows the corrosive moisture from the gas or oil furnace to weaken the mortar on the brick chimney. If this is the case a chimney liner also called stainless stain chimney liner or stainless steel chimney may be need then tuck point the chimney. Also penetrating moisture weakens the mortar that bonds the masonry units together; it also promotes premature deterioration of your brick causing brick chimney repair & tuck-pointing. When moisture finds its way into a defect on the brick and freezes, it will cause the brick face to spall (fall off), deflect, or displace. Once this happens, your brick is rendered useless, as it offers no structural support to the masonry structure.


Flue Covers and Caps

A flue cap is installed on the top of a chimney, and it prevents rain from flowing into the chimney as well as animals and birds from entering. A flue cap is typically made of sheet metal and some type of screen. They can be easily removed to clean the chimney and are available in many styles to compliment a home’s decor.
