"I can’t say enough good things about Jake and his construction company. He recently completed an addition on our home, and the entire experience was outstanding from start to finish. Jake was professional, dependable, knowledgeable, and took a lot of pride in his work. He kept us informed throughout the project, paid attention to the details, and made sure everything was done right instead of cutting corners. The quality of the finished addition exceeded our expectations and looks like it was always meant to be part of the house. It’s hard to find a contractor you can truly trust, but Jake is one of them. He showed up, followed through on what he promised, and treated our home with respect. We couldn’t be happier with how everything turned out. I would recommend Jake and his company without hesitation to anyone looking for quality construction work. Five stars all the way — we would absolutely hire him again!"

Basement Remodel questions, answered by experts

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

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.
