"Shire Group did an amazing job with the exterior and interior work done to an add-on room on my property. Ben and Isaac were great to work with on everything from communications, expectations and updates throughout the job. I'd highly recommend working with Shire Group!"

"This is an outstanding business and I would highly recommend them. I hired them several years ago to power wash my sister's huge house which was filthy on the outside. The team hand washed the whole house and worked so hard in 90 degree heat. They took a lot of pride in their work and did an outstanding job. The neighbors would walk by the house afterward and would not be able to put their hand on why it looked so good and when I told them it was because of the power wash that was done they wanted to know who did the work so they could make note of the company if they needed work done in the future. They have also done numerous gutter cleanings on my house and are reasonable priced, very professional, and do a very thorough job. The rep even made sure to get some of the dust from the shingles that had been in my gutter for a while scraped off so that it would not build up even further. I have never had a gutter company do that! I give this company my highest compliments. They are a pleasure to do business with."

"They were great! Rick is very transparent and always kept us up to date on how things were going. They also stayed within the estimate despite problems with the basement floor that led to a longer job and more work. We would hire them again without hesitation."

FAQs for basement remodeling projects in Columbus, WI

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.
