Waterproofing Your Investment

Basements are naturally prone to moisture and flooding, which can lead to costly damage. Before we begin remodeling, we prioritize waterproofing your basement to ensure that your investment is safe. By protecting your new space from potential water issues, you can enjoy your transformed basement worry-free for years to come.

  • Framing & Drywall: We can create new rooms, install drywall, and frame walls to reconfigure the space.

  • Ceiling Installation: From drop ceilings to custom designs, we’ll ensure the ceiling enhances both style and functionality.

  • Flooring Options: Choose from durable, moisture-resistant flooring options that suit your style.

  • Custom Built-Ins: Add value and elegance with built-in cabinetry, bars, fireplaces, and more.

  • Lighting & Electrical: We design lighting systems that brighten the space and highlight its features.
