"I couldn't be happier with the work. Andy was extremely helpful and punctual. I had quite a few estimates on my kitchen remodel and I felt like none of the contractors I talked to were really interested in what I wanted. Andy listened to everything I had to say and delivered. 

Not only was the work completed on time. It was top notch work and under budget. How often does that happen?

I would highly recommend Andy Scott and would definitely use him again in the future.

"Our son hired this company to finish his basement a few years ago and was so pleased with their work he hired them to
demolish an existing back porch and construct a large 3-season room on the back of his house.  As he expected, the work
was done in a timely manner and the room is beautiful and very well constructed.  These guys are excellent finish carpenters.
My husband was a carpenter in his younger days and if anyone is critical of workmanship, he is the one!  He may one day
hire this company to do some work for us.  All of us would highly recommend Neil and his brother for any job you may want
done.  I'm sure our son would be very proud to show his two rooms to any of you who might be looking for a experienced and
detailed team.  Thanks guys!  Keep up your good work.

"According to the website, the person we met with is a "Foundation Expert."  Per his advice, we needed about $8000 in beams because the cement blocks showed bowing/cracking.  This house is only 650 sq feet and built in the 1950s.  He basically implied that the walls had extensive damage and the house would never sell unless we put beams up.  He deemed the repairs done by a previous homeowner as very bad and said they needed to be fixed immediately.  The waterproofing system was an additional $3500.
The whole thing seemed more like a sales pitch using the fear factor of a bad foundation.  And, I was put off by the "buy now" price difference.  They would give me a "realtor discount" if I agreed to do the work and pay the deposit right away.  Like I'd ever spend $12K without getting other bids and researching the heck out of it.
We decided to hire a structural engineer that wasn't trying to sell us something to inspect the basement and foundation.  Paying the engineer a couple hundred bucks was worth every penny.  After a full inspection, his professional opinion was that there were no structural issues.  The engineer report states that while the repairs made by the previous homeowner made were "unsightly" they are effective.  Meaning - the method they used was ugly, but the support it provided was effective and adding additional beams was unnecessary. 
I would highly, highly recommend getting a structural engineer before hiring any company to basement repairs.  It saved us about $8000.

"David met with my husband and I to see what our plans were for our basement. He was very patient as both my husband and I had our own ideas still. He gave us options and a rough estimate with in 3 days of our first meeting.  As David and his crew started to reconstruction of our basement some of our needs changed. After the living area was constructed we decided to add a wet bar, which turned out beautiful. The spare bedrooms and extra bathroom turned out amazing. We added a Jacuzzi tub ( that was something I really wanted) and the tile work was detailed and flawless, as was the rest of the laminate flooring they laid. From start to finish we had an excellent experience with David and his crew.  I would highly recommend them for any size project. What we thought we wanted some what changed along the way and he was very patient and accommodating. I definitely feel that the price was fair and we couldn't be happier with our new remodel. Thank you Daughenbaugh Construction."

"The entire project, from initial quote to completion went very smoothly. Tim's professionalism, honesty and integrity were evident before, during and after the sale. Much easier to work with than the other companies we got quotes from. Jan was very helpful making sure we had all the tools we needed to choose the materials we wanted and scheduling. The crew worked tirelessly, completing the job in one day and cleaned up afterwards. Any and all issues were taken care of immediately. We would highly recommend Des Moines Area Roofing and would not hesitate using them again."

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.
