"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!"

"Ovation did a great job installing a new tiled shower in our basement bathroom. They were easy to work with on design and executed exactly what I wanted for a competitive price. However, the project took 2x the estimated time they rarely proactively communicated about timelines or who would be on the job site doing what when."

"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 questions, answered by experts

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

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?

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
