Firestone is full of newer neighborhoods and busy households, and our home remodeling services are built around exactly that kind of life. We finish basements into family rooms, home offices, and guest suites; we redesign kitchens for the way families actually gather; we modernize bathrooms; and we add the extra rooms and sunrooms that make a good home feel great. A lot of our Firestone clients bought a home with potential and are ready to unlock it — and that’s our favorite kind of project. Every job begins with a transparent plan and fixed-cost line items, so you can make decisions with confidence and watch your home transform without budget whiplash along the way.

Lefort Built describes itself as a Class A Licensed General Contractor. However, Colorado does not issue a statewide general contractor license, and local jurisdictions maintain their own licensing requirements. The Town of Firestone requires contractors working within town limits to obtain a current local contractor license. Firestone offers a Class A classification covering general construction work, except electrical and plumbing. Before your project begins, ask Lefort Built to confirm its current local license and verify it through the Town of Firestone Contractor Licensing Office . Permits and required inspections are managed by the authority responsible for your project location.

Lefort Built prepares complete permit packages from the start to help avoid delays caused by incomplete submissions and keep your project moving forward.
