Gastite certification

Certified Gastite CSST gas lines, natural gas only

The Plumbing Expert is certified in Gastite CSST, corrugated stainless steel tubing, for natural gas lines. Our CSST work is for natural gas only, installed, bonded, and pressure tested to code and to Gastite's own installation requirements.

New gas lines

Gas lines for furnaces, water heaters, stoves, dryers, fireplaces, and generators, sized from the manufacturer's tables for the full run, not estimated.

Bonding done properly

CSST must be bonded to protect against lightning related damage. Bonding is part of every Gastite install we do, not an extra and not an afterthought.

Pressure tested and inspected

Every line is pressure tested before it goes into service, and our gas work is done by licensed gas technicians. If it is not right, it does not get turned on.

Extensions and corrections

Adding an appliance, moving a line, or correcting CSST that was installed without proper bonding or protection: we assess what is there and quote the fix plainly.

Gas work is not the place for shortcuts. Certified installers, correct sizing, bonding, and a pressure test on every job: that is the standard, every time.

Questions

Gastite CSST FAQs

What is Gastite CSST?

Gastite CSST is corrugated stainless steel tubing used to run natural gas lines inside homes and businesses. It is faster to install than rigid black pipe in many layouts, and it must be installed and bonded to the manufacturer's specification.

Is your CSST work for natural gas only?

Yes. Our CSST installation is for natural gas lines only, consistent with how we size and install CSST across all of our gas work. Call (800) 659-1879 and tell us about your project.

What does Gastite certification mean?

It means our installers are trained and certified on the Gastite system: sizing from the published tables, approved fittings and termination methods, bonding requirements, and pressure testing.

Can you add a gas line for a stove or generator?

Yes. We run new natural gas lines for stoves, dryers, fireplaces, furnaces, water heaters, and standby generators, sized for the appliance and the length of the run.

Which towns do you cover?

We do certified Gastite CSST installation in Orangeville, Mono, Shelburne, Grand Valley, Erin, Caledon, Bolton, Alliston and Fergus.

“Ryan really helped save us a tremendous amount of anxiety and stress. Came on the weekend to replace our main shutoff that was consistently leaking. He arrived early, well prepared and ready for work. He was polite courteous and simple in explaining the repair each step at a time.”
