"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."

"⭐️⭐️⭐️⭐️⭐️ Absolutely Stunning Refinish – Highly Recommend! I couldn't be happier with the way our hardwood floors turned out! We had some old, torn-up floors that honestly looked like they were beyond saving—but the transformation is unbelievable. After the refinishing, they look like brand new floors, absolutely gorgeous, with a smooth, rich finish that completely elevates the look of our home. Not only was the quality of the work exceptional, but the price was also more than fair—especially considering the results. On top of that, they were incredibly professional: they showed up 15 minutes early, ready to work, and clearly take pride in what they do. It’s rare to find that kind of reliability and craftsmanship these days. If you're thinking about getting your hardwood floors redone, do it—and call these folks. I can't recommend them enough!"

"We hired Rowe Construction for the second time for our master bathroom, which was a much bigger project. The project included demolishing the old bathroom and building a more oversized bathroom that included moving walls, moving toilet and shower locations, adding a new large window (masonry), installing tiles and lighting, and building a new walk-in closet. Ryan's team did a great job, and we are delighted with the craftsmanship, detailing, and overall quality. Everybody on their team was friendly and ensured the house stayed clean during construction. If you are building a new space or remodeling, look no further. I will hire them again."

Customers say: Super punctual

"I cannot say enough good things about this company and the owner, Angelo. He designed and built a new dining room addition and remodeled my existing deck. He communicated with me every step of the way and responded immediately to any and all of my inquiries. Two years after the project was completed, I had a small issue. I called Angelo and immediately he scheduled a team to come and repair it for me. The quality the work is beyond reproach. I would recommend Angelo and AP contractors without hesitation."

FAQs for basement remodeling projects in Union, IL

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.
