What is the average cost of fireplace gas insert in New Brunswick in 2026?

Gas fireplace inserts in New Brunswick typically range from $4,500-$12,000 installed, with most homeowners spending $6,500-$8,500 for a quality mid-range unit including professional installation and venting modifications.

The unit itself runs $2,500-$7,500 depending on size, efficiency rating, and features. Basic 25,000-30,000 BTU inserts start around $2,500, while premium models with remote controls, variable flame height, and decorative surrounds reach $7,500+. Installation costs add $2,000-$4,500, covering gas line modifications, venting work, electrical connections, and finishing touches around the existing fireplace opening.

Several factors significantly impact your total investment. Venting requirements are often the biggest variable — if your existing masonry chimney needs a new liner or direct venting through an exterior wall, expect $1,500-$3,000 additional. Gas line work depends on your current setup; extending a line from the basement or upgrading from 1/2" to 3/4" pipe adds $800-$2,000. Homes with challenging access to the fireplace location or complex masonry modifications push costs toward the higher end.

All gas work must be performed by a TIS-licensed gas fitter — this isn't a DIY project. The contractor will obtain the required gas installation permit and coordinate the mandatory TIS inspection before the system can be used. Many homeowners underestimate the electrical requirements — most inserts need a dedicated 15-amp circuit for the blower and controls, which requires a licensed electrician and NB Power wiring permit if you're adding new circuits.

Efficiency matters significantly in New Brunswick's cold winters. Look for units rated at least 75% efficiency, though 80-85% models provide better long-term value. The higher upfront cost typically pays back through reduced heating bills, especially if you're currently heating with oil or electric baseboard.

Start by getting quotes from three licensed gas contractors who can assess your existing fireplace, chimney condition, and gas supply. They'll determine if your masonry opening needs modifications and what venting approach works best for your home's layout. Most quality installations take 1-2 days once permits are secured and materials arrive.
