"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

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

Kitchens and bathrooms are typically the most expensive rooms to renovate. The high cost is due to several factors, including expensive appliances like ranges, hoods, and refrigerators, as well as costly fixtures. The 'bones' of the room, such as electrical and plumbing, are also expensive to move or replace. Because of the vast amount of prep work, finishing, and specialized labor involved in a relatively small footprint, these projects can cost double or more than a living space remodel. Even when trying to renovate on a budget, kitchens and bathrooms will likely carry a hefty price tag.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.
