"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Damon and his crew did an excellent job on our bathroom. Full, down to the studs, remodel. They were courteous, respectful and very quick. The best experience with any home renovation was working with Damon... he was honest with the true scope of the project and delivered on all of his promises. He didn't up-charge when pivots needed to happen and was helpful with any design indecision. Can't wait to work with him again."

"We hired Nextgen Home Repair to remodel our already converted garage back house so we could turn it into a comfortable living space for a family member. Before the remodel, it technically functioned as a space, but it didn’t really feel livable or welcoming but now it definitely feels like a home!! They fully repaired and updated both the inside and outside of the garage. The interior feels completely refreshed and everything looks clean and brand new. On the outside, the repairs and updates made a huge difference too so it finally looks like it belongs with the rest of the main house. The team was easy to work with, communicated clearly, and made sure everything was done right. You can tell they care about the quality of their work. We’re really happy we chose Nextgen Home Repair."

Basement Remodel questions, answered by experts

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.
