"My basement turned out amazing! Full bathroom installed, including 3-person sauna. Electrical work, lightening, painting, drywall and matte finish black ceiling all turned out fantastic! Gordan’s crew were all terrific. Professional, hard working, and always cleaned up before leaving for the night. Highly recommend!"

"Top Bros completely gutted and remodeled the two outdated bathrooms in our condo. The building is over 100 years old, so there were some challenges with plumbing, framing, and leveling, but Top Bros didn't shy away from any of them. They tackled each challenge head on and transformed our bathrooms, ensuring that everything was done correctly. They were friendly, easy to work with and the final products turned out amazing. I would highly recommend working with them."

"Ryan was great and easy to work with. He helped us through the process. The work was very good and the cost was reasonable. Ryan and his crew were very professional and respectful. They were always on time and never felt like they were working on other projects and and never felt like they were falling behind. We love the remodel and everyone that has come over have been super impressed. We would recommend Ryan and his team for your remodel needs."

"HIRE THESE GUYS!!! Donâ t pay more for big name remodelers. We had a kitchen and master bath remodel as well as putting new flooring in basement and kids bathroom. The quality is exceptional. Johnny and Pablo were the team at our home. Both are very talented craftsmen with a keen focus on detail. No aspect was overlooked or taken for granted. The glass and tile work in our shower was fantastic as was the tile and cabinetry work in the kitchen. The owner, Ed, was terrific to work with and lived up to all our expectations. I canâ t recommend these guys enough. Pricing was right in our budget. Very, very impressed! Will definitely use them again!"

"Great Work! Very punctual top notch work for a affordable price. I made some changes in the middle of the project and they were still able to finish the project on time. The workers are very polite and respectful. They also clean up everyday before they leave. We highly recommend this company. Frank the owner and his men are very knowledgeable about the work they perform and they pay attention to detail. The prices they charge are lower then the competition but do a superior job and they work with alternative materials to fit your budget. We highly highly recommend Ultra Source Performance for any of your remodeling jobs! Ken and Terri from McHenry Illinois."

"I can't say enough about A P Builders and how absolutely wonderful they have been from start to finish. We completely gutted and remodeled our home and Angelo was upfront, honest, timely, and everything that was contracted was done to perfection. We had crew there every day from start to finish. He started on time and finished on time. Any change orders were handled professionally and solutions were found for any unforeseen challenges due to the age of my home. I highly recommend AP Builders for any of your home improvement needs."

"Our master bathroom remodel was just completed in Nov 2025 by Fernando & Chris. They both did a fantastic job and we are highly satisfied with the end result. We appreciated their professionalism, flexibility, quality of work, and attention to detail. We also valued their consistent work ethic and daily clean up. They offered some great suggestions that helped the room look even better than we had originally envisioned. The project was completed on time and on budget. They were genuinely pleasant, respectful, and wonderful to work with from start to finish. We would certainly recommend using them in the future."

FAQs for basement remodeling projects in Grayslake, 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.
