"We recently had our basement bathroom redone due to water damage from broken water pipes. It was a pleasure working with Angelo and his team who were all very professional and experienced. Angelo was in constant contact and made sure that all work was performed to my satisfaction."

"Chris and Jack have done multiple projects over the years for us from Bathrooms, full basement model and to our kitchen. We referred him to our neighborhood in Glencoe. Great company to work with. They do what they agree on and don't have hidden costs like other contractors. Highly recommend them."

"We had an excellent experience working with Robert Anthony from start to finish. They were professional, responsive, and incredibly detail-oriented throughout our kitchen remodel. His team completed our renovation on time, kept the workspace clean, and communicated with us every step of the way. The quality of the craftsmanship exceeded our expectations, and you can truly tell they take pride in their work. They transformed our kitcjen beautifully and made the entire process smooth and stress-free for my family. We are beyond happy with our kitchen and we couldn’t recommended him more."

"We could not be happier with the results. From the start we were impressed with Nick and his team. They pointed out big problems with our original plan that all the other contractors we spoke to missed and we worked together to transform the basement into a beautiful space while still retaining a large amount of storage space. Nick brought excellent ideas from his experience and provided options for us to choose from. He caught details we overlooked and helped us avoid mistakes. The crew was knowledgeable, courteous, professional, and hard working. What I appreciated most was how attentive they were to our project. There were no delays and everything ended up on time and on budget which is so rare these days. Plus they are just a pleasure to work with. I strongly recommend Nick’s Home Remodeling and we'll bring them back for all work on our home."

Basement Remodel FAQs, answered by experts

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.
