What we see in Denver basements

A Denver basement is more than framing and drywall.

The below-grade rooms in this city come with their own set of questions: water, radon, head height, and whether a bedroom down there is actually legal. Here is what we check before we build.

Most Denver basements we work on are in homes near Cherry Creek and the South Platte River, built not long after the city was founded in 1858. At 5,280 feet elevation, the dry mile-high air and the old expansive clay soils are part of every job here, and a few of these blocks sit inside a Denver historic district.

The egress window for a legal bedroom

If you want a bedroom in the basement, it needs its own emergency escape opening, an egress window sized to current code, and usually a window well when it is below grade. We cut the wall, set the window and well, and plan the room around it so it counts as a real bedroom and appraises like one.

Moisture before drywall

Older Denver basements in Wash Park, Berkeley, and Park Hill can be damp, and Front Range clay soil moves water toward foundations. We deal with grading, drainage, and vapor first, so we are never hanging drywall over a wall that sweats.

Radon is common here

Radon shows up in a lot of Front Range homes. When we finish a basement into living space, we plan for a mitigation system instead of sealing a problem behind new walls. It is one of the first things we talk about on the estimate.

Low ceilings and old foundations

A pre-war Denver basement is often low, with a rubble or short poured foundation and ducts running right where you want head height. We frame to save every inch we can, box in beams and pipes cleanly, and tell you honestly how the finished ceiling will feel.

Adding a bath and a wet bar

Most Denver basement finishes want a bathroom, and often a kitchenette for a guest suite or rental. That means new drain lines cut into old cast-iron, sometimes an ejector pump when the sewer sits high. We plan the plumbing runs so the fixtures drain right.

The Denver permit

Finishing a basement adds framing, electrical, an egress window, and often plumbing, so it pulls a permit with City and County of Denver through their E-permits system and gets inspected at each stage. We handle the paperwork and the inspections so the space is legal square footage.

Denver basement questions

What homeowners ask us.

Can I put a legal bedroom in my Denver basement?
Yes, but a basement bedroom needs its own emergency escape and rescue opening, an egress window sized to current code, and usually a window well if it is below grade. We plan the window and the well so the room counts as a real bedroom and passes inspection. Confirm the current opening requirements with the city.
Do I need a permit to finish a basement in Denver?
Yes. Finishing a basement adds framing, electrical, and often plumbing and an egress window, so it pulls a permit with City and County of Denver and gets inspected. We handle the permit and schedule the inspections. Confirm current fees with the city.
What about moisture and radon in a Denver basement?
Both matter here. Older Denver basements can be damp, so we deal with water and vapor before we ever hang drywall. Radon is common along the Front Range, so many finishes include a mitigation system. We test and plan for it up front instead of framing over a problem.
My Denver basement has low ceilings and a rough foundation. Can you still finish it?
Usually yes. A lot of older Denver basements are low with rubble or short poured foundations. We build the framing and mechanicals to keep the most head height we can, box in the beams and ducts cleanly, and tell you honestly what the finished ceiling will feel like before we start.
Are you licensed and insured?
Yes. JAC Enterprise is licensed and insured. License and insurance details come with your written estimate.
