"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 FAQs, answered by experts

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

You technically can paint wires in a basement ceiling, but there are several important safety and code considerations. It's safe to paint non-metallic sheathed cable as long as the labeling remains visible. You can also paint low-voltage wires and conduit and junction boxes to help them blend into your basement. 

However, you should not paint damaged or deteriorated wiring is a fire hazard because it poses a fire hazard. The same goes for painting over high-heat wires that connect to heat-generating appliances or systems. Be sure to avoid painting multiple coats onto any wires, as that traps heat and poses fire risks.

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.

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

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.
