Basement finishing in Broomfield.

Most Broomfield homes were sold with a big unfinished basement. We turn that empty space into a suite, a theater, or a family room, built to float over the expansive soils the way Broomfield requires.

What we see in Broomfield basements

The unfinished builder basement is the signature Broomfield project.

Broomfield filled in mostly from the 1990s through the 2010s, and builders in Anthem, The Broadlands, and McKay Landing left almost every basement unfinished. Finishing it is the most common remodel in town. At 5,348 feet elevation on Front Range expansive clay soils, near Big Dry Creek, the way a Broomfield basement is built matters as much as how it looks. Here is what we plan for.

The big unfinished space

Newer Broomfield homes came with a full unfinished basement under the whole footprint. We turn it into a legal bedroom suite, a theater, a gym, a wet bar, or a family room, on one plan and one crew.

Floating walls over expansive soils

Broomfield sits on expansive clay that heaves when it gets wet. The city requires finished basement walls to float above the slab on a gap, or void, so the concrete can move without cracking your finish. Your site soils report sets the exact void, often two to three inches or more.

Egress for a legal bedroom

Any basement bedroom needs its own emergency escape (egress) window and usually a window well. We size and cut the opening to meet current code and waterproof the well so it drains.

Radon on the Front Range

Radon is common in Front Range soils, so a lot of Broomfield homeowners add or check mitigation when they finish the basement. We plan for it while the space is open.

Floodplain and moisture checks

For a lower-level finish near Big Dry Creek, we check the Broomfield floodplain map for your address and handle slab moisture before any flooring goes down, so the finish lasts.

The Broomfield basement permit

A basement finish pulls a permit with the City and County of Broomfield Building Division and uses their basement finish questionnaire. We handle the application, the soils detail, and the inspections. Confirm current fees with the city.

"They remodeled my bathroom and built a metal railing around my staircase. They did a great job on both projects, timely and responsive to all my requests. I would recommend JAC to anyone in the area."

Broomfield questions

What homeowners ask us.

Do I need a permit to finish a basement in Broomfield?
Yes. A basement finish pulls a permit with the City and County of Broomfield Building Division under the adopted 2024 codes, and the city uses a basement finish questionnaire with the application. We handle the paperwork, the soils detail, and the inspections. Confirm current fees with the city.
Why do basement walls have to float in Broomfield?
Broomfield sits on expansive clay soil that swells and heaves when it gets wet. The city requires finished basement framing to float above the slab on a gap, or void, so the concrete can move without lifting and cracking your walls. Your site soils report sets the exact void, often two to three inches or more.
Can you add a legal bedroom in the basement?
Yes. A legal basement bedroom needs its own egress window and usually a window well. We size and cut the opening to meet current code, waterproof the well, and build the suite around it.
What can you build in a Broomfield basement?
Bedroom suites, a bathroom, a theater or media room, a gym, a wet bar, an office, or a big family room. Most Broomfield basements are wide open under the whole house, so there is room to do more than one thing.
Are you licensed and insured?
Yes. JAC Enterprise is licensed and insured. License and insurance details come with your written estimate.
