The Ultimate Spring Chimney Maintenance Checklist

Most homeowners forget about their fireplace the second the weather turns warm. But Spring is actually the most critical time for chimney care. Winter freeze-thaw cycles do more damage to masonry than heat ever will.

1. Inspect the Crown

The concrete slab at the top of your chimney (the crown) often cracks during winter as moisture freezes and expands. Small cracks let water into the structure all summer.

2. Check for Animal Nests

Birds, squirrels, and raccoons look for nesting spots in early spring. An uncapped chimney is their first choice. If you hear scratching or chirping, do not light a fire.

3. Remove Creosote Now

Leaving creosote in your flue over the humid summer allows it to absorb moisture and smell. It also turns acidic, which can corrode metal dampers and liners.

4. Test the Damper

Humidity can cause dampers to rust or stick. Make sure it still operates smoothly and creates a tight seal to keep your air conditioning from escaping up the flue.

5. Look for Efflorescence

White, chalky stains on your brick mean water is moving through the masonry. Catching this in spring allows for waterproofing before the next rainy season.
