"Joe reached out quickly and with the assistance of Alupe, they were able to swiftly install a new lock & snap floor professionally over a poorly tiled/grouted situation. There was a small snafu with the wax ring and leaking water from the toilet to the basement after the floor installation and Joe & Alupe came out immediately to remedy the leak. Joe also patched a hole in our upper level ceiling AND a small hole on the outside of our home. All is well and we will DEFINITELY have them back for future services!"

"We can't say enough good things about Chuck and his crew! We had a total kitchen remodel done that involved tearing down walls and installing new support beams in the attic. Everything from electrical to drywall, to installing new cabinets. From start to finish Chuck was easy to work with. Phone calls were always returned. The work was done in the time frame that was quoted. Every effort was made to contain the "construction dust" and the work area was cleaned and vacuumed before they left for the day. I wish we were able to post photos to show you what an excellent job they did. If you are looking for a contractor that is honest, experienced and a pleasure to work with then Milliman & Sons Builders is who you need to call. Not only would we use them again, we already have Chuck working on our next remodeling project."

"We hired Oak Ridge Construction to remodel a home in Morton Illinois while we were living in Minnesota. They listened closely to what we wanted the house to be. Ana sent design samples to our home in Minnesota and worked out all of the final details VIA virtual meetings. They were able to complete the demolition before we left Minnesota and finished the job while we lived in the basement for the next 6 weeks. The job was completed to our 100% satisfaction. Mike's attention to detail was phenomenal! Ana's design was perfect! We are so happy with the final results and intend to use them again for another project next summer. I highly recommend Oak Ridge Construction!"

"This was our 2nd. time hiring Trevor and was very pleased with his work. The 1st. job was a living room ceiling which turned out great. This time we needed a fence section replaced. Trevor was very prompt in getting the job completed in one day. We have more work to be done and will definitely contact Trevor again. We highly recommend T's Remodeling because they are very professional and they're prices are reasonable and fair."

FAQs for basement remodeling projects in Washington, 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.
