We Repair Chimney Crowns on Long Island NY

chimney crown long islandExpressway Chimney repairs and replaces damaged chimney crowns on Long Island. Your chimney was most likely built with brick and mortar, which is very porous. If you don’t have a properly fitting chimney crown to protect your chimney from water, your chimney is subjected to what is known as the “freeze-thaw effect”. This happens when temperatures fluctuate around 32 degrees–a little above one day, a little below the next. This causes water to be absorbed by the brick and mortar, which then expands and contracts with the outside temperature changes and may cause serious and expensive damage both inside and outside your home. As a result, the homeowner has experienced chimney crown damage, wall leaks, and foundation and basement issues due to lack of protection from the continual freezing and thawing of the water inside the bricks.

The skilled professionals from Expressway Chimney know properly functioning chimney crowns are the solution to avoiding the damage caused by the rain, snow, and ice freezing and thawing.

A chimney crown is simply a “lid” to cover and seal your chimney and deflect water and moisture away from the brick and mortar. It covers your chimney from flue liner to the edge of the chimney.

The Chimney Safety Institute of America (CSIA) explains it, “All masonry chimney construction materials, except stone, will suffer accelerated deterioration as a result of prolonged contact with water. Masonry materials deteriorate quickly when exposed to the freeze/thaw process, in which moisture that has penetrated the materials periodically freezes and expands causing undue stress. Water in the chimney also causes rust in steel and cast iron, weakening or destroying the metal parts. CSIA elaborates, “Chimney (crowns), also called rain covers, are probably the most inexpensive preventive measure that a homeowner can employ to prevent water penetration and damage to the chimney. Chimney (crowns) have long been recognized as an important chimney safety and damage prevention component.”
