Quick answer

cK Builders frames and finishes new rooms and basements across St. Paul, Mendota Heights, Dakota County and the south metro — framing, insulation, drywall, doors, trim, flooring and paint, with electrical and plumbing by licensed trades under permit. A basement bedroom needs an emergency escape and rescue opening (egress window) under the residential building code. The 2025 Cost vs. Value Report lists a Twin Cities average of $52,745 for a basement remodel with a full bath.

Basement finishing we do

A whole lower level or a single room: family and rec rooms, bedrooms with egress windows, home offices, gyms, guest suites, bathrooms, wet bars, laundry rooms, storage and closets. And not just basements. We frame and finish new rooms anywhere in the house.

That covers framing, insulating exterior walls, soffits around ductwork and pipes, drywall, interior doors, casing and baseboard, LVP, carpet or tile flooring, finished stairs and paint. Electrical and plumbing for lighting, outlets, bathrooms and bars go through licensed trades under permit, and we pull the building permit and handle the inspections.

Frequently asked questions

Can you add a bedroom in my basement?

Yes, if the space can meet code for a sleeping room — most importantly an emergency escape and rescue opening (egress window). We’ll check that during the walkthrough.

Do I need a permit to finish a basement?

Yes. Finishing a basement is permitted work in Minnesota cities, and electrical and plumbing need their own permits by licensed trades. We pull the permits.

How much does it cost to finish a basement?

The 2025 Cost vs. Value Report lists $52,745 as the Twin Cities average to finish a 20×30 ft lower level with a full bath and wet bar. A simpler room without a bathroom costs less.

Can you frame and finish just one room?

Yes. Single rooms — a new bedroom, an office, a closet — are welcome. We handle the framing, drywall, doors, trim and paint.
