"We found Bielefeld Construction on Home Advisor and was surprised when Ray responded because we hadnâ t previously had a lot of luck on Home Advisor. We hired them for a master bedroom remodel and are very happy with the final outcome. We made a few changes here and there and Ray was very accommodating. All employees and subcontractors were pleasant, considerate and meticulous in what they brought to the project. We would definitely recommend Bielefeld Construction and use them again if the need arises. 5 star organization!"

"This project was for remodeling 3 bathrooms and a total kitchen remodel. The construction workers were very skilled. They were very good about listening to our suggestions along the way. I would suggest that the construction foreman be present along with the salesman when the project is estimated so that technical issues and be better clarified. For example, we removed carpet and installed DVT vinyl flooring which resulted in different leveling issues. These issues could have been resolved early on rather than brainstorming solutions with the workers at the ends. The project was done on time as scheduled even though we added some changes along the way. The electrical subcontractor should have clarified options for wiring for the kitchen better. The only negative comment I can make is that we thought the cost was a little high, however the quality was very good. The final project is beautiful."

"I highly recommend Skyler, he is such a professional handyman, he does the work very quickly and you can trust him. He will come in advance with professional equipment, remove the wooden floor with tools, and remove the nails exposed to the outside to avoid safety hazards. He is also very nice, cheerful and patient. It was a great experience to work with him."

Basement Remodel FAQs, answered by experts

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.

Envision the type of bar experience you'd like to create for your guests. For example:

  • Does your basement have enough finished space for bar stools or seating?

  • What type of additional lighting would set the tone for the room?

  • Are there basement windows or an HVAC system?

  • Do you need new plumbing in your basement for a proper wet bar?

  • Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?
