"My basement got water damage to it. Everything had to be removed. Their company came right in and made my basement look beautiful. From the fine drywall work to the paint job. We will hire again."

My family and I have nothing but fantastic things to say about Mark and Judy.  They both were easily accessible by phone or email, professional, and patient regarding the numerous questions I frequently put to them.  Mark was very straightforward with me, and worked hard to overcome the obstacles that popped up.  Bottom line- I was able to obtain a loan at a good fixed rate, and am very satisfied.  I would (and do) recommend them to my friends.

"We are so happy with the work of WilMarc Construction- we have had them do two major home remodels for us- both times, Willie came out and listened to our ideas and what we had in mind and then gave thoughts of his own (which were always better than ours) and the results were both beautiful and reasonable. Our first project was redoing a kitchen and we had thought an extension would be best and he came up with a more economical solution to combine a couple of rooms, change windows and location of the bathroom. He always did what he said he was going to do and didn't overcharge. Our last project was just finished- installing hardwood floors and redoing two upstairs bathrooms. When we started pricing out flooring at a couple of flooring places, we realized it would be better to ask Willie his opinion and get an estimate and we ended up doing two bathrooms as well as the floors and replacing the stairs--all things that needed to be done for a reasonable cost. I would recommend asking Willie his opinion on what your plan is and your choices, he has done a lot of projects and sees the final project so with regards to durability and beauty he can offer really helpful suggestions with material."

Basement Remodel FAQs, answered by experts

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

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.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.
