How Do We Finish Your Basement?
MOISTURE PROTECTION
Every basement finishing project in Central Iowa starts with moisture control. Our clay-heavy soil holds water against your foundation, and about 71.6% of Iowa homes test above the EPA action level for radon.
Before we frame a single wall, we check for leaks, cracks, and dampness throughout your basement. We seal foundation walls, install vapor barriers, and make sure your sump pump works right.
This step costs about $1,500 to $5,000, depending on your home’s needs, but it protects every dollar you spend after it.
- Interior drainage system inspection and sump pump testing
- Foundation crack repair and waterproof wall coating
- Radon testing and mitigation system installation when needed
WINDOWS & EGRESS
Iowa’s building code, adopted under Iowa Administrative Code 481-301.8, requires at least one emergency escape and rescue opening in every basement and in each basement sleeping room. The opening must provide a minimum of 5.7 square feet of net clear opening, measured as the actual space available when the window is fully open from the inside.
The sill height must be no more than 44 inches above an adjacent permanent interior standing surface that is at least 36 inches wide, 18 inches deep, and no more than 24 inches high. The code allows that standing surface to be factored into the sill height measurement, which can affect how a window is positioned in some basement configurations. Your local building official confirms compliance during inspection.
Each opening must lead directly to a public way, yard, or court. We cut into your foundation, install a code-compliant window and well with proper drainage, and handle all permit filings and inspections.
Most egress window installations in Central Iowa run $2,500 to $5,000 per window. Beyond the safety requirement, these windows bring natural light into a space that most homeowners have never seen lit by daylight.
- Egress window installation meeting Iowa's 5.7 sq ft minimum opening
- Window well with drainage to prevent water buildup
- Natural light planning to reduce the below-grade feel
FRAMING
Framing is where your basement floor plan comes to life. We use pressure-treated lumber (per IRC code) on every piece of wood that touches concrete. This is an Iowa basement essential because our humid conditions cause untreated wood to rot within a few years.
Our crew frames out your bedrooms, bathrooms, closets, and open living areas.
We also build soffits and chases to hide ductwork, pipes, and beams so your finished basement has clean sight lines throughout.
- Pressure-treated bottom plates on all concrete contact points
- Room layout framing for bedrooms, bathrooms, and living areas
- Soffit and chase construction to conceal mechanical systems
PLUMBING
Adding a bathroom, wet bar, or laundry area to your basement remodel means running new plumbing lines. We do this work while the walls are open because it is the fastest and least expensive time to route supply and drain pipes.
A basement bathroom rough-in in Central Iowa typically costs $3,000 to $7,000, depending on how far you are from the main drain stack.
We pull all required permits and schedule inspections so your project stays code-compliant from day one.
- Bathroom rough-in for toilet, sink, and shower or tub
- Wet bar drain, supply lines, and laundry hookups
- Permit filing and inspection scheduling with your city
ELECTRICAL
Every basement finishing project needs a solid electrical plan, and we map out every outlet, switch, and circuit while your walls are still open. Iowa adopts the NEC 2023 with state-specific amendments that govern all residential wiring.
One rule most Central Iowa homeowners don’t know: Iowa’s amended Article 210.8(A)(5) requires GFCI protection on every 125-volt, 15- and 20-ampere receptacle in your basement, finished or unfinished. That’s not just outlets near water. It’s every single standard outlet in the space.
Iowa also requires GFCI protection on sump pumps, dishwashers, and microwave ovens under its amended Article 210.8(D), which adds protections beyond the base NEC 2023.
In our basement remodeling projects across Central Iowa, we also wire for the future. Need a home theater, office, or workshop down the road? We run the wiring now during the finishing process, so you do not have to open walls later.
Costs vary based on room count, circuit needs, and scope of work.
- Outlet and switch placement per Iowa electrical code spacing
- GFCI-protected circuits in bathrooms, bars, and laundry areas
- Future-proofed wiring for home theater, office, and workshop use
HVAC & VENTILATION
Before we run a single vent, we check whether your current HVAC system can handle the extra square footage.
A finished basement can add 500 to 1,500 square feet to your home’s heating and cooling load. If your furnace or air conditioner is already working near capacity, pushing more air to the basement means less comfort upstairs.
We do a load calculation to find out if your existing system can cover the new space or if you need an upgrade, a supplemental unit, or zoned controls. Then we extend ductwork and add supply and return vents in every new room.
Iowa basements sit below the frost line, so they naturally stay cooler in summer and retain heat well in winter.
We also install bathroom exhaust fans and balance airflow across your whole house so every level stays comfortable.
- Supply and return vent installation in every finished room
- Bathroom exhaust fan setup for moisture and odor control
- Whole-house airflow balancing after basement HVAC extension
INSULATION
Proper insulation is what makes your finished basement comfortable year-round and keeps energy bills in check. We assess wall conditions before choosing an insulation approach because the right solution depends on your foundation type, moisture history, and how the space will be used.
Iowa’s residential energy code, adopted under Iowa Administrative Code 481-301.24, requires basement wall insulation based on the climate zone applicable to your project location per the 2012 IECC. The code allows either R-15 continuous insulation applied to the face of the foundation wall or R-19 cavity insulation installed between studs, with R-13 cavity plus R-5 continuous also permitted as an alternative path. We recommend continuous rigid foam or closed-cell spray foam on foundation walls in most Central Iowa basements because they do not create gaps where humid air can condense against the concrete surface. Fiberglass batt insulation can be used correctly when conditions allow for it, but it requires careful installation to avoid moisture issues in below-grade applications. Read our full cost-benefit analysis of spray foam insulation in Iowa to understand how insulation choices affect your long-term energy costs.
We also insulate the rim joist at the top of the foundation wall, which is one of the most significant sources of heat loss in most Iowa homes and one of the most cost-effective places to add insulation during a basement finishing project. Most homeowners notice the difference in comfort and energy costs within the first heating season. Costs vary based on basement size, wall condition, and the insulation approach that best fits your specific situation.
- Rigid foam or closed-cell spray foam on foundation walls
- Rim joist air sealing and insulation to stop heat loss
- Sound dampening insulation between basement and first floor
DRYWALL & CEILINGS
Drywall is what turns your framed basement into real, finished rooms. We hang, tape, mud, and sand every surface to a smooth, paint-ready finish.
In bathrooms and areas near water, we use moisture-resistant drywall to prevent mold and damage. For ceilings, you choose between drywall, which gives a clean, seamless look, or a drop ceiling, which lets you access plumbing and wiring above.
Iowa’s residential building code, adopted under Iowa Administrative Code 481-301.8, requires a minimum 7-foot ceiling height for habitable basement living space, with bathrooms allowed at 6 feet 8 inches. Beams, ducts, and other obstructions can drop as low as 6 feet 4 inches. In our basement finishing projects across Central Iowa, we plan ceiling layouts around these clearances to give you the most usable height in every room.
- Moisture-resistant drywall in all bathrooms and wet areas
- Level 4 or Level 5 smooth finish for paint-ready walls
- Drywall or drop ceiling options based on access needs
PAINTING
We paint your basement walls and ceilings before the new floors go in. This keeps drips, dust, and overspray off your finished flooring.
Basements need a moisture-resistant primer coat and high-quality, low-VOC paint rated for below-grade spaces. Light colors help reflect the limited natural light in most Central Iowa basements.
We work with you to pick colors that make rooms feel larger, brighter, and connected to the rest of your home’s style.
- Moisture-resistant primer on all new drywall surfaces
- Two coats of low-VOC, below-grade-rated paint
- Color planning to maximize brightness in low-light spaces
FLOORING INSTALLATION
Basement floors sit on a concrete slab, so not every flooring material holds up well.
Iowa’s temperature swings and below-grade moisture mean you need flooring that can handle it.
Luxury vinyl plank, porcelain tile, and engineered hardwood are the best options for Central Iowa basement finishing projects.
We install a subfloor system when needed to add warmth, cushion, and a moisture barrier between your new floor and the concrete.
Basement flooring typically runs $3 to $12 per square foot installed.
- Luxury vinyl plank, porcelain tile, and engineered hardwood options
- Subfloor system for warmth, cushion, and moisture protection
- Radiant heated floor options for bathrooms and living areas
LIGHTING
Basements have little to no natural light, so a smart lighting plan is what makes yours feel like the rest of your home.
We install recessed LED can lights for even coverage and efficiency, plus task lighting in work areas and accent lighting where you want to create atmosphere.
Dimmer switches and smart controls let you change the mood for movie night, game day, or everyday use.
We plan lighting room by room based on ceiling height, layout, and how you will use each space.
- Recessed LED can lights sized for your ceiling height
- Task lighting for bars, offices, and workspaces
- Dimmer switches and smart lighting control options
CUSTOM FEATURES
This is where your basement remodel becomes something your family actually uses every day.
We design and build custom features like wet bars, entertainment centers, built-in shelving, home offices, and storage systems.
Want a home gym, wine room, craft area, or kids’ play space? We build it to fit your basement’s layout and your family’s lifestyle.
Every custom feature we add is built to match the look and feel of the rest of your home.
- Custom wet bars, entertainment centers, and built-in storage
- Home office, gym, playroom, and hobby room buildouts
- Design-matched cabinetry and millwork for a seamless look
FINAL FINISHES & WALKTHROUGH
Finishes bring your entire basement finishing project together.
We install baseboards, door casings, trim, and all final hardware. Cabinet pulls, outlet covers, light switch plates, and towel bars go in. Then we do a detailed walkthrough with you to check every corner, every switch, and every surface.
We do not consider the project done until you are completely happy with the result.
Most basement finishing projects in Central Iowa take 6 to 12 weeks from start to this final step.
- Trim, baseboards, door casings, and hardware installation
- Final detail placement for a polished, move-in-ready space
- In-person walkthrough and quality review before project handoff

- Frequently Asked Questions
FAQS About Basement Finishing
In Central Iowa
How long does it take to finish a basement?
Most basement finishing projects take 6 to 10 weeks from start to finish. The exact timeline depends on the size of your basement and what features you want.
Adding a bathroom or wet bar takes longer than a simple family room. We give you a clear schedule before work begins so you know what to expect.
Weather and permit timelines in Des Moines, Ankeny, or your city can also affect the schedule.
Do I Need a permit to finish my basement?
Most cities in Central Iowa require permits for basement finishing.
Permits ensure that electrical, plumbing, and framing work meet local building codes. Skipping permits can cause problems when you sell your home or file an insurance claim.
We handle the permit process for you and schedule all required inspections.
how much does a basement finishing cost in des moines?
Basement finishing in Central Iowa typically costs between $25 and $75 per square foot.
A basic finish with carpet and drywall costs less than a project with a bathroom, wet bar, or custom features.
The final price depends on your basement size, layout, and material choices. We provide detailed estimates before any work starts, so there are no surprises.
How Do You prevent moisture problems in a basement?
We start every project by checking for water issues and fixing them first.
Vapor barriers, sump pumps, and drainage systems keep your basement dry. Iowa soil holds a lot of water, so moisture protection is not optional here. We also choose flooring and materials designed for use below grade.
These steps protect your investment for years to come.
Does Finishing a basement, add value to my home
A finished basement adds usable space that buyers find attractive.
Keep in mind that appraisers value below-grade space differently from above-grade rooms. Read about the real impact of basement finishing on home value before you start planning.
Quality work, proper permits, and good finishes make the biggest difference when it comes time to sell.
Is finishing a basement better than building an addition?
It depends on your goals and budget.
Basement finishing typically costs less per square foot than home additions because the foundation and roof already exist. However, above-grade space is valued higher in appraisals.
We put together a guide on basement finishing vs. home additions to help you decide which option fits your situation.
