"Bear Remodeling did an amazing job on my bathroom remodel. The team was nice, courteous and worked hard to get what I wanted. They paid attention to every detail and made sure the design matched my idea. They also did some interior painting and made the whole room look cohesive and stylish. I was so impressed I asked about adding a room to my house and they gave me some great ideas. If you need a contractor for any remodeling project, call Bear Remodeling!"

"Michael and his team were incredibly professional. They remodeled two of our bathrooms, including doubling the square footage in our master suite. Michael stood behind his work and insured. We were fully satisfied with the product. Throughout every stage of the process, he kept a clean and tidy, worksite, and was respectful of our families time and space. We’ve referred Michael to many of our friends because of the great work and professionalism he exuded on the job. We plan on using Michael and his team for our kitchen makeover later this year."

Basement Remodel FAQs, answered by experts

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.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

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.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable.
