What we see in Centennial basements

Centennial is a basement-finishing town.

Centennial was incorporated in 2001, but its houses came earlier, and they came with basements. At about 5,722 feet elevation, in neighborhoods like Willow Creek and Piney Creek near Cherry Creek, most 1970s to 1990s homes have a big lower level that was framed and left empty. Here is what that project really involves.

Big empty square footage

The typical Foxridge or Homestead basement is a large open box with a rough-in for a bath and not much else. That is a whole extra floor of house. We plan it as a suite, a theater, a gym, a wet bar, or a wide-open family room.

Egress for a legal bedroom

A basement bedroom needs its own egress window and usually a window well, so someone can get out in a fire. If yours does not have one, we cut the foundation opening and set the well. We size it to meet current code.

Radon on the Front Range

Radon is common across the south metro. Finishing the basement is the right time to install or rough in a mitigation system, so the room you just built is safe to spend time in. We suggest testing before and after.

Expansive clay under the slab

Front Range clay soils swell when they get wet and can heave a slab. We frame with the right gap details and watch for old moisture so your new floor and walls are not fighting the ground under them.

Low lots and drainage

Some low-lying lots near Cherry Creek and Big Dry Creek sit in a mapped floodplain that SEMSWA manages. We check the drainage and grading around the house first, so we are not finishing a basement that takes on water.

The Centennial permit

Finishing a basement adds walls, wiring, and often plumbing, so it pulls a permit under the city's Land Development Code (Chapter 12) and gets inspected. We handle the permit and the inspections from framing to final.

Centennial basement questions

What homeowners ask us.

Can you finish a big unfinished Centennial basement?
Yes, and it is the most common project we do here. Most homes in Willow Creek, Foxridge, and Homestead have large unfinished basements. We frame, insulate, wire, and trim that space into a suite, a theater, a gym, a wet bar, or a family room, done by one crew start to finish.
Do I need an egress window for a basement bedroom in Centennial?
Yes. A legal basement bedroom needs its own emergency escape (egress) window, and usually a window well, so someone can get out and a firefighter can get in. If your basement does not have one, we cut the opening and set the well. The window must meet current code, so we size it to what the city requires.
What about radon in a Centennial basement?
Radon is common across the Front Range, and a finished basement is a good time to deal with it. We can rough in or install a radon mitigation system so your new lower level is safe to spend time in. We suggest testing before and after.
Do I need a permit to finish a basement in Centennial?
Yes. Finishing a basement adds walls, electrical, and often plumbing, so it pulls a permit with the City of Centennial and gets inspected. We handle the permit and the inspections. Confirm current fees with the city.
Are you licensed and insured?
Yes. JAC Enterprise is licensed and insured. License and insurance details come with your written estimate.
