"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 FAQs, answered by experts

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

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.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable.
