"This is the second time I've turned to Mark for help in getting a home loan. The reason I'm a repeat customer is that Mark is great. He always gets me the absolute best rate and is an honest, tell-it-like-it-is person - so very appreciated during the confusing and scary process of getting a mortgage.
I tend to run a little on the neurotic side, and Mark handled my constant badgering and near freak-outs with great finesse, providing just the right amount of hand-holding and straight-up advice. This time around, I bought my home through a private sale, meaning neither party used a realtor. So I needed even more attention and guidance. Mark not only did a great job with the mortgage, he also gave me invaluable advice on issues related to the sale but outside his scope, such as home inspection.
A big THANKS to Mark. I couldn't have done it without you and Judy!

"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

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.

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.
