Installation & Construction

If you’re adding to your home, remodeling a kitchen or bath, or just installing a new sink or disposal, we can take care of all your plumbing needs and work with your contractor. As a service provider for Rinnai, Weil-McLain, AO Smith, and State Water Heaters we have their products available directly, but we’re also glad to work with other suppliers.


Some types of plastic piping can cause ongoing maintenance problems and actually lower the value of your home at resale. In these cases, repiping is often the best option. We’re able to handle whole-house repiping and have become experts at doing these projects with as little disturbance to the home as possible.
