For Contractors

At Lavallee Systems, we often work directly with builders and remodelers. We know that, as a sub-contractor, we represent your business. Rely on our team to complete your new construction or remodeling projects in a professional and timely manner.

Builders know we pride ourselves on designing and installing complete, efficient plumbing, electrical, and HVAC systems. Working with remodelers, we are often consulted to solve unique plumbing, electrical, and HVAC “issues” in older homes. Our team can help make your client’s home more comfortable and efficient. Diagnosing, and solving issues is our area of expertise. We work with you to repair, replace, or modify the existing system – all based on the specific needs of your client.
