🧱 5 Chimney Repairs You Should Tackle Before Winter

As colder weather approaches, it’s crucial to prepare your chimney for the heavy use it’ll get throughout the heating season. At Chimney Crickets, we’ve seen too many homeowners in Minnesota and Wisconsin wait too long—only to face major repairs mid-winter. Scheduling chimney repairs before winter is the key to avoiding surprise breakdowns, water damage, or safety risks when you least expect them.

So, what should be on your radar this August? Here are the top 5 chimney repairs every homeowner should address before the cold sets in:

1. Cracked or Crumbling Masonry

Damaged brickwork or deteriorating mortar joints allow moisture to seep in—and when that moisture freezes, it expands, causing major structural problems. A quick tuckpointing or brick repair now can save your chimney from collapsing later.

2. Chimney Crown Repair

The crown is your chimney’s first line of defense against water. Cracks in this concrete top layer are a major source of chimney leaks. Before freeze-thaw cycles take over, ensure your crown is solid and professionally sealed.

3. Chimney Flue or Liner Issues

A damaged liner increases the risk of chimney fires and carbon monoxide leaks. Whether your flue needs resurfacing with HeatShield or a full relining, August is the best time to get it done before the heating season starts.

4. Chimney Cap or Flashing Repair

Missing or damaged caps let in rain, snow, animals, and debris. Faulty flashing leads to water leaks near the roofline. If you notice water stains, rust, or drafts—these parts may need immediate repair or replacement.

5. Creosote Removal & Cleaning

Built-up creosote is highly flammable and one of the most common causes of chimney fires. August is ideal for scheduling your chimney cleaning while techs have availability and weather conditions are still favorable.
