Repairing Chimney Leaks

By | Tagged with: Tags: , , | Comments Off on Repairing Chimney Leaks

A chimney leak is the last thing any homeowner wants to experience. It doesn’t only affect your chimney! A chimney leak can cause damage to other parts of your home because the water runs through the hidden portions of your home. For this reason you should always assume a leak is caused from the chimney, no matter how far it may be from the chimney itself.

Chimney leaks also cause damage to supports, walls, ceilings, and wall coverings near the chimney, along with a host of extensive damage to the chimney itself.

Water and Your Masonry Chimney

Masonry is constructed of multiple materials, all of which are adversely affected by moisture. If water is allowed to penetrate your chimney, it can destroy your masonry from the inside out, causing rust, stains, deterioration, weakening, decreased efficiency, and increased fire risk. The best way to prevent water penetration and damage to your chimney is to have it inspected annually and waterproofed by a professional. The average homeowner won’t notice a leak until a problem is visible. By this point there can be substantial damage behind-the-scenes. A professional will see a problem before it causes damage.

Diagnostics and Repair

An inexperienced chimney sweep might repair the damage that makes your chimney a hazard, but a certified chimney sweep will repair the damage, diagnose the problem, and prevent it from reoccurring.

Common Causes of Chimney Leaks

Magic Sweep sees chimney leaks often, and year round. Common causes include a missing or damaged chimney cap and damaged or missing chimney flashing. These two components are vitally important to prevent water penetration. Magic Sweep technicians are trained and experienced in installing chimney caps and flashing to prevent leaks.

Common Chimney Leak Damage

  • Spalling
    A chimney leak during the winter can be especially damaging to your masonry because of the freeze/thaw affect. The water penetrates the masonry, freezes, expands, then melts, moves further into the masonry, and repeats the cycle. This causes spalling, cracking and crumbling masonry. It can be repaired through a process called tuck pointing in which a chimney sweep removes the bricks, replaces mortar and each brick. It is a tedious job because the new mortar should match the old in consistency, color, and strength.
  • Liner Deterioration
    When moisture mingles with soot, it is corrosive and can damage the chimney liner quickly. In this case a certified chimney sweep can reline the chimney. Magic Sweep can fix your chimney liner damage using HeatShield® cerfractory technology. When we reline your chimney with HeatShield®, we restore your liner instead of replacing it completely, saving you time and money.
  • Structural Damage
    Our chimney experts are certified masons who can rebuild and repair your damaged chimney. Your firebox, hearth, and chimney can all be affected by a chimney leak, and once the leak is repaired, the masonry should be repaired. Only a certified chimney sweep specializes in the construction and repair of a masonry chimney.
