Fireplace Repairs: Common Issues, How to Fix Them
When you live in Wellington, your fireplace isn’t just for show. It’s a workhorse during winter—cracking away on cold nights, battling the coastal damp, and standing up to those relentless southerlies. But like anything that works hard, it wears out. And when it does, things go downhill fast. Smoke starts spilling into the room, bricks crack, and the heat disappears.
The good news? Most common fireplace problems can be fixed—and often prevented—with a bit of know-how and the right help.
This guide cuts through the noise to explain what goes wrong, why it happens more often in Wellington homes, and how to fix it. If your fire’s playing up, you’re in the right place.

Wellington’s climate accelerates wear on fireplaces, especially near the coast.

Kapiti Woodfires services all of Wellington and offers expert repairs across the region.
Why Fireplace Repairs Are So Common in Wellington Homes
The impact of wind, salt air, and moisture on fireplace components
Wellington’s weather is part of its charm—but it’s brutal on wood fireplaces. That salt-heavy air off the Cook Strait creeps into fireboxes, flues, and flashing. Moisture builds up fast, and if your fireplace isn’t properly sealed or cleaned, things start to deteriorate. Rust appears inside the unit, mortar weakens, and soot becomes a problem far quicker than in drier regions.
The cost of delaying maintenance
Add to that the strong winds and temperature fluctuations, and you’ve got a recipe for chimney movement and firebrick cracking. Even a well-installed fireplace can show signs of wear within a few years if it’s not serviced.
Wellington homes often use their fires daily in winter—especially in spots like Featherston, Otaki, and Upper Hutt where nights are colder. High usage plus harsh weather equals more repairs.
Most Common Fireplace Problems in Wellington
Cracked Firebricks and Damaged Fireboxes
This one’s easy to spot: you’ll see visible cracks in the brickwork or metal walls of your fireplace. These cracks reduce heat efficiency and can expose your home to fire hazards. Cracks often come from thermal expansion, where the firebox heats up too fast, or from moisture getting in over summer.
Chimney and Flue Obstructions
Birds love nesting in flues. So does creosote, the thick black tar from unseasoned wood. Both create dangerous blockages. If you’re seeing more smoke inside than out, odds are your flue’s clogged. Blocked flues reduce draw, which means poor burning and smoke blowback into your lounge.
Smoke Not Drawing Properly
When your fire refuses to draw and sends smoke back into the room, it’s usually a pressure issue or blockage. Wind can also cause backdrafts if the chimney isn’t capped properly. This is common in exposed areas like Lyall Bay and Porirua. Damaged flashing or seals around the chimney can make the problem worse.
Doors Not Sealing or Closing Properly
If the door on your wood burner is loose or won’t latch, it’s likely the gaskets are worn or the door frame has warped. Poor seals let oxygen in, leading to faster burns and lower heat retention—not to mention potential safety issues.
Rust and Corrosion Inside the Unit
Coastal homes in Kapiti, Foxton, and Levin see rust far sooner than inland properties. If your fireplace isn’t regularly cleaned and dried out in the off-season, moisture can lead to rusted grates, weakened seams, and even flue decay.
DIY Fix or Call the Pros?
What You Can Safely Do Yourself
Clean out the ash pan weekly in winter.
Check the door seals—close a piece of paper in the door; if it pulls out easily, the seal’s gone.
Wipe down the firebox with a dry cloth to check for rust or debris.
What Should Be Handled by a Certified Installer
Any structural repairs—cracked fireboxes, warped flues, chimney leaks—should only be done by a licensed installer. Same goes for any work that affects the airflow or compliance of the system. DIY mistakes here can void insurance or lead to major hazards.
How to Avoid Recurring Repairs
Schedule Annual Servicing With a Certified Technician
Hands down, the best thing you can do is book an annual check-up. Kapiti Woodfires offers full servicing across the Wellington region. Whether you’re in Lower Hutt, Otaki or Paraparaumu, their team checks seals, clears blockages, and catches minor problems before they turn into big repairs.
Book a certified fireplace repair service with Kapiti Woodfires to stay ahead of the issues.
Use the Right Firewood and Burn Practices
Green or wet firewood causes creosote buildup, which clogs your flue and creates more smoke. Always use seasoned hardwood, avoid burning pine, and let your fire breathe rather than smothering it with logs.
Keep an Eye on Wear-and-Tear
Before you light up for the season, do a visual check: are the bricks intact? Do the doors close tightly? Is the flue cap still secure? Early signs of damage are easy to miss—until they become expensive.
