"It went great! The crew that did the work were diligent and professional, polite and courteous, respectable to me personally, to my home. They did a great job of cleaning everything up when the job was done. We had a couple of little kinks. They were taken care of quickly with apologies. The completed new bathroom is even more beautiful than I could have anticipated. Gorden was easy to work with. He explained everything and helped with decisions. He is respected by his crew. I'm completely pleased with the work performed. When I'm ready for another project G.R. Construction Co will get my call. Thanks Gordy and your crew for my beautiful new bathroom."

"All of these 5 star reviews got dumped on the Angi page, dated 2/2024. All show shiny basements & what appears to be excellent work & reviews claiming excellent communication. It's how I came about the referral - as well as their Facebook ads. Not sure if they bit off more than they could chew, but communication has been awful if not non-existent. The home visit seemed great! But I had to email them for the quote afterwords. Then a visit to the showroom a month later was dirty, plant dirt lying around, no bathroom available to the customers, giant weeds outside of the building they purchased. If you're presenting yourself as professional contractors, appearance of a showroom where you host customers is a reflection of your work. I didn't hear from them in over 4 wks. I emailed & was met with an excuse & zero delivery of promise for final proposal. We are taking our business elsewhere. We just wasted 3 months for nothing."

"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."

FAQs for basement remodeling projects in Trevor, 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.
