Superb company. My wife, Lena and I engaged the company to erect a room in the basement of a townhouse that we had bought for her daughter last year.

What Is Basement Remodeling?

Basement remodels often involve more than just drywall and flooring. We handle all the critical infrastructure work to make sure the space is not just finished — but dry, safe, and code-compliant.

• Moisture mitigation and waterproofing prep

• Insulation and framing

• Electrical, lighting, and HVAC installation

• Full bathroom additions or upgrades

• Flooring installation (LVP, tile, carpet, etc.)

• Egress window additions for legal bedrooms

We also understand the local permitting and building code requirements for basement projects in the Philadelphia area, including Bucks and Montgomery counties.

During your walkthrough and estimate, we’ll talk about how you plan to use the space and any must-haves you want to include. Whether you already have drawings or just an idea in your head, we’ll help you shape a clear scope of work.

While we don’t advertise in-house design, we often guide layout decisions and connect clients with trusted design partners if needed.
