Kitchen Plumbing FAQ
Do you work with kitchen contractors and general contractors?
Yes. A.J. LeBlanc Heating regularly works as the plumbing subcontractor on kitchen remodel projects across Southern NH. We coordinate with your GC or kitchen contractor to stay on schedule.
Do I need a permit for a kitchen faucet replacement?
Not for a like-for-like faucet swap. For new plumbing, moving drains, adding supply lines, or rough-in work, a permit is required in Southern NH. We pull every permit and schedule inspections.
Can you install a kitchen sink in an island?
Yes. Island sink installations require vent routing through the floor and subfloor, which is a bit more involved than a wall sink. A.J. LeBlanc Heating handles island sink plumbing regularly across Southern NH.
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.
