"Jonathan did an amazing job with our bathroom remodel. This was a complete remodel with an oversized shower, patterned ceramic tile, beautiful sliding glass doors, and of course the sink, toilet and flooring. The job was done very well and in good timing. He was very professional and kind. I would highly recommend his team for any work that you may need done!"

"They picked up the project that we could not finish. We had already bought the majority of the materials. They gave us a reasonable estimate for the deck, so we asked them to also quote the screened in porch. They finished all within 2 weeks. There was excellent communication and they were both very professional. I would recommend Nate and Mike!"

Basement Remodel questions, answered by experts

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

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.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
