Buying a Home With a Fireplace? What You Should Check First (NZ Guide)

A fireplace can look great, and still be unsafe, non-compliant, or costly to fix.

Written by: Nadia Crighton – The Chimney Sweep Company

Buying a home with a fireplace can feel like striking gold. For many New Zealand buyers, a fireplace represents warmth, comfort, and that classic Kiwi winter vibe.

But here’s something we see far too often in our day-to-day work:

A fireplace can look great, and still be unsafe, non-compliant, or costly to fix.

The Chimney Sweep Company has done all the hard work for you! If you’re buying a house with a fireplace in New Zealand, this guide walks you through what to check first, based on what we regularly encounter when inspecting chimneys in real homes.

Why Fireplaces Deserve Special Attention When Buying

Unlike most features in a home, fireplaces involve:

• Open flames

• Smoke and airflow

• Structural components

• Ongoing maintenance

In our experience, many NZ homes still have fireplaces or flues that:

• Haven’t been inspected in years

• They were used by previous owners without proper maintenance

• Or haven’t been used at all, which can be just as risky

• Old earthquake damage

A standard pre-purchase building report often does not include a full chimney or flue inspection, leaving issues undetected until the first fire is lit – cue the GASPS.

1. Get a Pre-Purchase Chimney Inspection (Not Just a Builder’s Report)

This is one of the most important steps, and one many buyers don’t realise they need.

When we carry out chimney inspections, we’re checking for things a general building inspection won’t always cover, including:

• Creosote buildup

• Blockages (especially bird nests)

• Cracked or deteriorated flues

• Structural damage inside the chimney

• Signs of previous chimney fires

• Poor draft or airflow problems

  
  

We regularly see chimneys that look perfectly fine from the outside but have serious internal issues that only become obvious once the fire is used. If you’re buying a home with a fireplace, a chimney inspection should be treated as essential, not optional.

2. Safety Warning Signs Buyers Should Look For

When viewing a property, keep an eye out for these red flags.

🚩 Visual signs

• Crumbling bricks or mortar around the fireplace

• Rusted metal components

• Cracks inside the firebox

• Soot staining on walls or ceilings

• Persistent smoky or musty smells (even in summer)

  
  

🚩 Usage clues

• The fireplace “hasn’t been used in years”

• Smoke marks around the opening

• Reports of smoke coming back into the room

  
  

In our experience, fireplaces that haven’t been used for long periods often develop blockages, moisture issues, or nesting problems, all of which can create serious safety risks.

3. Compliance: Is the Fireplace Legal and Fit for Use?

Fireplace regulations in New Zealand have changed significantly over time, particularly around emissions, clearances, and installation standards.

Depending on the age of the home, issues can include:

• Older wood burners that no longer meet clean air rules

• Modifications made without consent

• Incorrect flue installations

• Inadequate clearances to walls or ceilings

  
  

We often help homeowners understand:

• Whether an existing fireplace is still legal to use

• What upgrades may be required

• What changes are allowed under the current council rules

  
  

Older fireplaces aren’t always illegal, but they may require upgrades to remain safe and compliant.

4. Insurance Risks Many Buyers Overlook

This is one of the biggest surprises for new homeowners.

Many insurance policies require fireplaces to be:

• Properly maintained

• Regularly cleaned

• Used safely and correctly

  
  

If a fire occurs due to:

• Excess creosote

• A blocked flue

• Structural chimney failure

  
  

…insurance claims can be declined if there’s no evidence of proper maintenance.

We often recommend buyers ask:

• When was the chimney last swept?

• Is there any maintenance history?

  
  

If there’s no record, it’s safest to assume the chimney needs inspection before use.

5. Bird Nests & Blockages: A Common NZ Problem

In New Zealand, chimneys are a favourite nesting spot for birds, especially in spring and summer.

We frequently find:

• Fully blocked flues

• Partially collapsed nests

• Debris restricting airflow

  
  

These blockages can:

• Force smoke and carbon monoxide back into the home

• Increase fire risk

• Make the fireplace unsafe to use

  
  

A professional inspection can identify and resolve these issues before they become dangerous.

6. The Cost of Skipping a Chimney Check

From what we see on the ground, skipping a chimney inspection can lead to:

• Unexpected repair costs

• Emergency callouts during winter

• Fire or smoke damage

• Insurance complications

• Stress and safety risks you didn’t budget for

  
  

By comparison, a pre-purchase chimney inspection is a small upfront investment that can save thousands later.

7. Fireplace Buyer Checklist (NZ)

Before lighting a fire in a newly purchased home, make sure you’ve ticked off:

☐ Chimney professionally inspected

☐ Flue clear and structurally sound

☐ No bird nests or blockages

☐ Fireplace compliant with local rules

☐ Insurance requirements understood

☐ Chimney swept before first use

☐ Properly seasoned firewood is ready

A fireplace should be a feature that adds comfort and warmth, not risk or unexpected cost.

If you’re buying a home with a fireplace, taking the time to inspect it properly gives you confidence that it’s:

• Safe

• Compliant

• Insurable

• Ready to enjoy
