"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

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.
