"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"We had a complete kitchen remodel done by Beneflipper Construction. Damon Benefield (owner) and his crew did a fabulous job. The work included demolition of the entire kitchen down to the studs. Damon increased the size of the see-through area between the kitchen and the dining area. New plumbing, electrical, cabinets and appliances were put in. The great part about the project was that Damon was in contact with us for the entire process. Plus, he was spot on with the estimated time of completion. We are thoroughly pleased with the workmanship, ease of communication and timely manner in which our project was completed. I would highly recommend Damon Benefield and Beneflipper Construction without reservation. In fact, we loved the ease of working with Damon, that we had him do our bathroom remodel, as well. Thank you! Thomas Morrison & Dondi Austin Long Beach, CA"

"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

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.

While bathrooms and kitchens are nearly equal in terms of renovation difficulty, kitchens are the most challenging. Kitchen design, layout, electrical, and plumbing needs all depend on each other for the success of the entire project, and mistakes early in the project can cause trouble later on.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

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.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.
