"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

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!

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.
