"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."

"I recently had the pleasure of working with Adam to have epoxy floors installed in my home, and I couldn't be happier with the results. From start to finish, he demonstrated professionalism, attention to detail, and a genuine passion for his craft. The floors look absolutely stunning—smooth, glossy, and perfectly even. The transformation in my space is incredible, making it not only more functional but also incredibly stylish. He took the time to explain the process, answer all my questions, and ensure that every detail was executed flawlessly. If you're considering epoxy flooring, look no further. Adam’s expertise and dedication to quality are second to none. I highly recommend him for any epoxy flooring needs—you won't be disappointed!"

Basement Remodel FAQs, answered by experts

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

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.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

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, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.
