Chimney Repairs To Make Before Winter

Summer is the time for vacations, spending more time outdoors, and relaxing. However, it’s also an excellent time to catch up on household maintenance and repairs before winter arrives, particularly chimney repairs. Let’s look at the most common chimney repairs to make before lighting that first fire of the cold season.

Chimney Waterproofing, Hightstown, NJWaterproofing or Replacing The Flashing

Chimney flashing is metal material installed where the chimney meets the roof to direct water away from seeping into the spaces where there would otherwise be a gap to prevent leaks—like masonry materials, flashing wears out over time. Summer is the perfect time for a trained chimney specialist to inspect the flashing for damage and repair or replace it. If the flashing is in good condition, it’s also wise to re-apply a waterproofing product to provide additional protection against leaks.


Tuckpointing is the process in which a professional masonry technician repairs damaged mortar joints. Over time, mortar joints deteriorate through the repeated freeze/thaw cycle. If the damage becomes too severe, it can lead to your chimney becoming unstable. Tuckpointing removes the deteriorating mortar and replaces it to shore up the bond and give your chimney a fresh look.

Firebox Repair

Besides the chimney, the firebox is often the most neglected component of your fireplace system and is typically the one in most need of repair before winter. Every season, your firebox is exposed to high temperatures and chemical reactions that break down the masonry materials, leading to poor performance and safety concerns. Like your chimney, your firebox may need repairs via tuckpointing and replacing damaged bricks to keep it running efficiently and safely.

Crown Restoration

The chimney crown is crucial in protecting your flue and maintaining a healthy, efficient fire. The crown is typically a slab of concrete that sits on top of the chimney to keep debris and critters from getting into the flue, and it’s angled to direct water away. Like all masonry materials, the crown is subject to freeze/thaw cycles, which cause it to wear down, crack, and crumble. If your chimney crown is in disrepair, you must fix it as soon as possible to prevent further water erosion and the onset of mold and mildew.

Damper Repair

The chimney damper is a device that regulates airflow. Dampers are prone to damage from rust and constant usage. If your damper is difficult to open and close, it may need to be repaired or replaced.

Once creosote thickens, it requires removal from a trained professional using advanced tools. During chimney cleaning, it’s wise to have your chimney professional perform a thorough inspection of every chimney and fireplace component, and summer is the best time to do this because it gives you ample time to conduct repairs if needed instead of waiting until the last minute.

Moreover, if you need repairs, they’re easier and safer to perform during warm weather.
