Customers say: True professional

"Andy's crew is very professional and did a great job. My home was difficult to get drywall into. They carried each sheet upstairs. Walls finished very well. Dedicated spray equipment created smooth application of knock down texture. Ceilings Looks great. No damage. No surprises. Priced right, but they weren't the cheapest option. On time. No excuses. They protected my property and cleaned up after themselves. As a property manager, I will definitely use Scott's again."

"I can't say enough good things about our experience with Des Moines Area Roofing. Tim was honest and helpful in assessing our roof and worked with us and our insurance. Brandon and the crew were professional and hard working, staying until dark each night, and Jan helped intercede with our insurance company. I wouldn't hesitate to use them again."

"CAUTION - when relying on Issac We needed our chimney rebuilt. Issac estimated it and finally we received a starting date. After, working an hour he said the job was too big for him. (some damage to our metal pieces). We request that he would paint it after we find another handyman. Once done he came back and quoted over $100 an hour to paint the chimney. He kept push us out on his calendar. We dropped him. He had us paid for the hour that he worked on the Chimney before exiting. Very poor communication if we are scheduled? If he is starting on the day he last told us? Problem answering texts."

FAQs for basement remodeling projects in Knoxville, IA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
