"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."

Basement Remodel questions, answered by experts

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.

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

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.

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. 

Kitchens and bathrooms are typically the most expensive rooms to renovate. The high cost is due to several factors, including expensive appliances like ranges, hoods, and refrigerators, as well as costly fixtures. The 'bones' of the room, such as electrical and plumbing, are also expensive to move or replace. Because of the vast amount of prep work, finishing, and specialized labor involved in a relatively small footprint, these projects can cost double or more than a living space remodel. Even when trying to renovate on a budget, kitchens and bathrooms will likely carry a hefty price tag.
