Can You Install a Fireplace in an Existing Home? Yes — Here’s How
Quick answer: yes — a fireplace can be installed in almost any existing South African home, even without a chimney. A modern insulated flue system routes through the roof or an external wall, and most installations are finished in a single day.
“But My House Doesn’t Have a Chimney”
This is the most common thing we hear, and it stops far too many people. Modern freestanding and built-in fireplaces don’t need a traditional brick chimney. They use a stainless steel flue system: single-wall pipe in the open room (which radiates useful heat), switching to insulated twin-wall sections wherever it passes through a ceiling, roof space or wall. The flue exits through the roof with proper flashing, or up an outside wall.
Which Rooms Work?
- Open-plan living areas — the classic choice; a 7–9kW closed-combustion unit heats the whole space.
- Bedrooms and studies — a compact 3–5kW unit is enough; yes, this is done all the time.
- Double-storey homes — very doable; the flue routes through the upper floor or externally. Costs a bit more for the longer run.
- Apartments — the exception. Without roof access, a wood fireplace usually isn’t possible; a bio-ethanol or electric unit is the realistic route.
What the Job Involves
- You send us a photo of the room and the outside roofline — we confirm the flue route and quote.
- We deliver the unit and protect the work area.
- Flue goes in: ceiling penetration, insulated sections through the roof space, flashing and cowl on top.
- The fireplace is positioned to SANS clearances, connected, and test-fired.
- You get a walkthrough on running it, and we leave the site clean. One day, in and out, for most homes.
What It Costs in 2026
For a typical single-storey home: R3,500–R4,800 installation labour plus the flue system. A complete project — a good mid-range fireplace, full flue and installation — typically lands between R18,000 and R40,000. Our fireplace installation Cape Town page has the full price table.
Wood, Gas or Electric?
If you have roof access, a wood-burning closed-combustion unit gives the most heat per rand — see our wood fireplace buying guide. Gas suits homes that want instant, effortless heat (we install the gas line and issue the Certificate of Compliance). Electric is the fallback when structural work isn’t possible.
