"Jerry remodeled my basement last year before I sold my house. Also painted living room and dining room and replaced light fixture. He and his partner were courteous, hard-working and neat. They did a great job. My house sold in 3 days-I think partly because of the good work Jerry did."

"HVAC was not draining properly and had to reroute drain tube to sump pump well with improved gravity feed for proper drainige (needed to go behind paneling in basement walls). They did an excellent job, works like a charm!"

"We hired David to remodel our basement late last year. There was a late start initially, however the crew picked it up and did an amazing job with our basement. David clearly understood our key requirements and built the plan to accommodate the asks. He was flexible and most importantly available at all hours when we were out for selections. He recommended best options for floor tiles, cabinets and all accessories. We are extremely happy with the output and the great work Davidâ s crew did with our basement. We strongly recommend them."

"We had more than 80% of the old house remodeled with new additions. It’s a daunting task and huge project. However, Dimitritis and Joshua made it easy and did a great job in completing our dream home. Joshua was fantastic managing the daily tasks and excellent with details. They were very responsive in re-addressing even with minor adjustments. Definitely recommend."

Basement Remodel FAQs, answered by experts

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

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.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

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

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.
