Running a Gas Line in a Century Home: Galt, Hespeler and Downtown Kitchener
The job is the same as in a new build. The route is not.

Why old houses cost more
Rubble-stone foundations you can't easily penetrate, plaster-and-lath walls that crack if you fish through them carelessly, joist bays already full of knob-and-tube remnants and old plumbing. Every one of these adds time to a gas run through Galt, Preston, Hespeler or the older streets of Kitchener.
Black iron vs CSST
Rigid black iron is cheapest per foot and fine in open basements. CSST (corrugated stainless tubing) snakes through finished spaces with far fewer fittings and access cuts, and in century homes it's usually the right call. It must be bonded to the electrical system — a step some installers skip.
Realistic numbers
A range or dryer line that would be $700–$1,000 in a new-build basement is often $1,100–$1,500 in a century home. A BBQ line is less affected because it usually exits near the tie-in.
What to insist on
A route walk before work starts (so you know where any access cut will be), a pressure test at the end, and the tag and paperwork that go with a certified install.
