When the crackle of the fire fades and warmer days begin to take over in New Zealand, it can be easy to forget about your chimney. However, chimney maintenance doesn't stop when the fires go out. Preparing your chimney for the off-season is an essential part of home care. In this blog, we’ll walk you through simple, effective ways to maintain your chimney through spring and summer.
Why Off-Season Chimney Care Matters
Neglecting your chimney over the warmer months can lead to a host of problems. Birds and rodents may move in, moisture can creep in and cause damage, and leftover soot and creosote can become dangerous when ignored. Off-season chimney maintenance helps:
Extend the life of your chimney
Prevent animal nests and blockages
Minimise moisture damage
Ensure it’s safe and ready to go when winter returns
1. Book a Professional Clean and Inspection
Before you close out the season, schedule a professional chimney sweep. A certified sweep will:
Remove creosote and soot
Check for blockages or damage
Inspect the flue, flashing, and chimney crown
This step ensures your chimney is clean, safe, and free from residue that could damage your flue or spark a fire later.
2. Install a Chimney Cap (or Check the Existing One)
A chimney cap is your best line of defence against the elements and unwanted visitors. It keeps:
Birds and possums from nesting inside
Rain from entering and damaging the flue
Leaves and debris out of the chimney shaft
If you already have a cap, check that it’s secure and rust-free.
3. Protect Against Moisture Damage
New Zealand’s wet springs can wreak havoc on an unprotected chimney. Water is one of the most damaging elements for masonry and steel components. To prevent issues:
Ensure your chimney crown is sealed and in good condition
Repair any cracks in the bricks or mortar
Consider a water-repellent treatment for masonry chimneys
4. Pest-Proof the Chimney
Birds love to find warm, quiet spaces to nest—and your chimney is prime real estate during spring. Even small critters like rats and mice can find their way in. To deter pests:
Use a cap with mesh screening
Remove overhanging branches or climbing plants near the chimney
Inspect and seal any small gaps or entry points
5. Close the Damper (But Check for Ventilation Needs)
Once your chimney is clean and no longer in use, close the damper to prevent airflow (and animal entry). But be cautious: if your fireplace still requires ventilation or has a pilot light, ensure there is adequate air circulation.
6. Consider a Seasonal Inspection of the Fireplace Unit
Spring and summer are ideal times to have your entire fireplace inspected—especially if you’re planning renovations or upgrades. Gas fireplaces, in particular, should be checked for leaks or faulty ignition systems.
7. Use the Time to Plan Upgrades
With your fireplace out of use, now is a great time to plan any improvements:
Repointing chimney brickwork
Installing a new fireplace surround
Updating insulation or flue liners
Tackling these jobs in the off-season ensures everything is complete before the cold weather returns.
