Benefits of Chimney Waterproofing This Spring 

Springtime is a time to tackle many of the chores that need attention after the long, cold winter. When you start to make that list, don’t forget about your chimney. Not only do you need a chimney sweep and inspection, but springtime is a great time to consider waterproofing your chimney. Let’s take a look at the benefits and the process that is involved. 

Benefits of Chimney Waterproofing:

Prevent Chimney Fires: As water seeps into your chimney’s masonry, the freeze-thaw cycle begins, causing cracks. Cracks in the masonry prevent good airflow up the chimney, exposing the chimney walls to high heat and potentially allowing creosote to accumulate. The risk of a chimney fire is accelerated.

Prevent Costly Repairs from Water Damage: Water is quite detrimental to your chimney. Water can seep into the bricks and mortar, leading to leaks and cracks. Waterproofing creates a protective barrier that prevents water and moisture from entering.

Chimney Longevity: Minimizing moisture intrusion reduces the risk of structural damage. 

Helps prevent mold and mildew from growing, potentially causing health issues to you and your family. 

Chimney Waterproofing Process:

Chimney Inspection: The chimney will be thoroughly inspected before any work is performed. The technician will look for:

-Damaged mortar joints

-Cracked or spalling bricks.

-Leaks or flashing issues.

Chimney Sweep: A good sweep is recommended before waterproofing or any repairs. 

Cleaning the Chimney Surface: Dirt and debris, moss, mildew, and efflorescence will be cleaned and removed from the exterior masonry. 

Repair Damages: After the inspection and a sweep, any damage can be repaired to ensure the solution provides good service.

-Replace damaged bricks.

-Fix cracks in the crown or flashing.

-Tuckpointing (repair mortar joints).

Drying time: The chimney should be dry before applying the waterproofing solution; this can take 24 -72 hours.

Apply a Water-Repellent Solution: a breathable professional solution is applied. The technician will use a low-pressure sprayer or a brush roller.

Curing Time: After the waterproofing sealant is applied, it will need a few hours up to a full day to cure. It will continue to strengthen over the next several days. 

Final Inspection: Our technician will conduct a quick inspection to ensure even coverage, no missed spots, and proper sealing around edges and joints.
