"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!"

"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

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

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.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.
