A fireplace insert is a sealed, more efficient appliance fitted into an existing fireplace opening — wood, gas or pellet. The install is more involved than sliding a box in: the insert usually needs a properly sized liner running up the flue, correct clearances, and a connection matched to the unit and fuel. We assess the existing opening and flue, confirm the insert suits them, and install with the right liner and venting. Gas connections are handled by licensed professionals.
What homeowners notice
- You want more efficiency and heat from an open, drafty fireplace
- You're upgrading to a sealed wood, gas or pellet insert
- Your open fireplace loses more heat than it gives
- You're replacing an old or failed insert
How we diagnose it
- We measure the existing opening and assess the flue
- We confirm the insert fits and the flue can take the required liner
- We determine the correct liner size and venting for the unit and fuel
- We check clearances and the connection requirements

What affects the price
We don't post flat prices, because an honest number depends on what we actually find. These are the factors that move it:
- Insert type and fuel
- Liner size and length required
- Clearance and connection work
- Gas or electrical trades where needed
When to stop using the system and get it evaluated
- Don't operate a new insert until the liner and venting are correctly installed and inspected where required
How to prepare for the visit
- Measure your fireplace opening if you can
- Decide on fuel type and whether gas or power is available
Applies to
A note on scope: Gas and electrical connections are performed by appropriately licensed professionals; the liner is sized to the appliance.
Questions homeowners ask
Why does an insert need a liner?
A sealed insert needs a correctly sized liner running up the flue so it vents properly and safely. Sizing follows the appliance, which is why we confirm the flue can take the right liner before installing.
Will an insert really heat better?
A sealed insert is far more efficient than an open fireplace, which loses much of its heat up the flue. The gain depends on the unit and install being matched correctly.
