Prevent Leaks & Protect Your Investment With Masonry Waterproofing

A chimney leak can be one of the most frustrating, damaging, and expensive home issues to deal with, especially if it’s not promptly identified and repaired. Unfortunately, many leaks go unnoticed until the damage is done. That’s one of the reasons why we urge homeowners to schedule annual chimney inspections with a Chimney Safety Institute of America (CSIA)-certified professional. During an inspection, we’ll check the chimney system from top to bottom, looking for blockages, damage, weak points, and of course, leaks. But keeping up with annual inspections isn’t the only way to protect your chimney system against leaks. Here at Old Dominion Chimneys, we specialize in masonry waterproofing services, which can help keep water out of your masonry and out of your home.

The waterproofing products we use are specially formulated to protect chimney masonry, so unlike common sealants and waterproofing products, they allow the masonry to breathe. You see, the brick and mortar of your chimney need to be able to expel vapor created during combustion, but common waterproofing products actually trap these vapors inside. What a chimney needs is a product that will seal out water molecules but allow vapor molecules to pass freely – and that’s just how the waterproofing products we use work.

Signs Of A Chimney Leak

When it comes to leaks, prevention really is the best method. But knowing the signs of a leak can be incredibly helpful as well. Here are some common signs that you may have a leak in your chimney system:

  • Water pooling or dripping in your firebox
  • Rust streaks along your chimney or down into your fireplace and firebox
  • Water-stained ceilings and walls surrounding your chimney
  • Cracked brick and receding mortar joints
  • Discolored or vegetation-riddled brick
  • Crumbling or spalling brick

Keep an eye out for any of these signs! If you think you may have a leak in your chimney, it’s imperative that you act quickly. Water can be incredibly destructive in a relatively short amount of time and the cost of repairs can add up quickly.
