Insert Install you can actually trust
An open masonry fireplace is roughly 10% efficient — most of your heat goes up the flue. A properly installed insert with a full-length stainless liner runs 70–80% efficient and pays back on gas or wood spend within a few seasons. We size, install, line, and commission the appliance.
Every Newmarket job is quoted in writing before any work begins, and backed by a 5-year workmanship warranty.

Insert Install in Newmarket — common questions
Does an insert need a new liner?+
Yes. Every manufacturer and CSA B365 require a continuous, correctly sized liner from the insert to the top of the chimney. A stub connector is a failed install.
How much does a fireplace insert install cost in the GTA?+
Installation runs $1,290–$3,200 excluding the appliance. Liner length, chimney condition, and offsets are the main cost drivers.
Which is cheaper to run, gas or wood insert?+
At current Ontario rates a wood insert is cheaper per BTU if you buy seasoned cordwood; a gas insert costs more per hour but needs no loading, ash removal, or annual sweeping.
