Basement Finishing FAQs

When finishing a basement, the process typically involves adding framing, drywall, insulation, electrical wiring, plumbing, and other necessary elements to create a livable space. On the other hand, remodeling takes it a step further by not only finishing the space but also renovating and updating existing features to enhance functionality, style, and comfort in the basement.
Enhancing the value of your home is within reach by finishing your basement. With a carefully planned and expertly executed design, a finished basement provides extra living space, improved functionality, and a boost to resale value. Expect a return on investment of approximately 70-75% for your basement finishing project.
In Maryland, it is indeed mandatory to obtain a permit for finishing a basement. At Capstone Waterproofing Solutions, we take care of the hassle for you by assisting with the permit application process and diligently following up on its status. You can rely on us to navigate the bureaucratic requirements, so you can focus on what matters most.

It was necessary to have the basement waterproofed because any heavy rain would cause anxiety about the basement flooding.

We shopped around and Capstone Waterproofing Solutions was highly recommended. Service was outstanding. Since the work was completed this past weekend, as Mr. Jones said, I’m looking forward to some good rain and the comfort of knowing my basement won’t flood.

My neighbors have already contacted them.

Lead by Mr. Jones, the install crew were very respectful of my property and handled everything with extreme care and detail. I posted some pictures of their great work. Give them a call you won’t be disappointed.
