Plumbing Work Planned for the Whole Project
A good plumbing installation has to work behind the walls as well as it looks at the fixture. We plan supply piping, drains, venting, shutoff valves, fixture locations, and water-heating connections around the way the space will be used. For remodels, we inspect the existing piping before promising that it can be reused. For new homes, additions, and ADUs, we coordinate the interior plumbing with the general contractor and other trades. Manchester homeowners get straightforward recommendations and a finished system that is accessible for future service.

Plumbing Installation FAQ
Can you install fixtures I bought myself?
We can install many customer-supplied fixtures when they are code-compliant, complete, compatible, and suitable for the application. We can also supply the fixture and include it in the written quote.
How much does a bathroom remodel cost?
The plumbing scope for a new tub, toilet, vanity faucet, shower valve, and related supply or drain work typically runs $3,500-$8,000, depending on fixture complexity and pipe rerouting. A.J. LeBlanc Heating handles the plumbing and any related HVAC or electrical work in our scope. We coordinate with your general contractor, or can bring in a general contractor we work with regularly to manage the broader renovation. Finish work is quoted separately by the GC.
Do you install tankless water heaters?
Yes. We install Navien and Rinnai tankless systems throughout Manchester. We evaluate the gas supply, venting, incoming water temperature, and simultaneous hot-water demand before sizing the unit. A properly sized system can provide continuous hot water and free utility-room space.
Can you install a dishwasher or garbage disposal?
Yes. We install dishwashers and garbage disposals. A dishwasher installation includes the water supply and drain connections, plus an air gap where required. A disposal installation includes the drain connection, electrical connection, and testing.
