Hannegan Construction specializes in high-quality basement finishing and remodeling, helping homeowners unlock the full potential of their homes with thoughtful planning, durable materials, and exceptional craftsmanship.
A finished basement is one of the most effective ways to expand your home’s livable footprint without the cost of a full addition.

We handle layout design, framing, insulation, electrical, plumbing, flooring, and all the custom features that give your basement its finished, polished look.
As an experienced basement finishing contractor, we know that below-grade spaces come with unique challenges.

Our team ensures your project is built on a solid foundation with waterproofing, drainage considerations, and materials designed to perform in basement environments.
You’ll work with a dedicated project manager who keeps communication clear and the process organized from design through completion. We believe in transparency, clean job sites, and delivering a finished space that enhances your home’s value and fits your lifestyle.
