How do you handle basement waterproofing during remodeling?

Waterproofing is a very important part of basement remodeling—especially in Philadelphia, where heavy rain and high water levels are common. At NK Construction and Design , we make sure your basement stays dry by using smart solutions like: Sump pumps Drainage systems Waterproof coatings on walls and floors This helps protect your space from leaks, mold, and moisture—so your new basement stays safe and comfortable for years to come.

A basic finishing project — framing, drywall, flooring, and lighting — sits at the lower end of the range. Projects that include bathroom additions, custom built-ins, high-end finishes, or significant waterproofing and structural work move toward the higher end. Every basement is different.
