Kitchen Plumbing FAQ
Do you work with kitchen contractors and general contractors?
Yes. A.J. LeBlanc Heating handles the plumbing and any related HVAC or electrical work in our scope. We coordinate with your general contractor or kitchen contractor. If you do not have one, we can bring in a general contractor we work with regularly to manage the broader renovation.
Do I need a permit for a kitchen faucet replacement?
A like-for-like faucet replacement may not require a permit. New plumbing, relocated drains, added supply lines, and rough-in work may require one depending on the project and municipality. We confirm the requirements and coordinate permits and inspections when needed.
Can you install a kitchen sink in an island?
Yes. An island sink needs a code-compliant drain and vent design without a nearby wall. A.J. LeBlanc Heating plans the piping around the cabinet layout, floor framing, and local requirements.
What brands of faucets and fixtures do you install?
We install any brand you choose, including Kohler, Moen, Delta, and Brizo. A.J. LeBlanc Heating can supply the fixture or install one you have already purchased.
