Our Step-by-Step Basement Remodel Process

Finishing a basement requires precision, planning, and expert execution. At Mammoth Construction, we follow a step-by-step process that ensures efficiency without cutting corners.

  1. Design & Planning
    – We start with your vision: whether it’s a home theater, office, or extra bedroom. We create design ideas, check local codes, and map out everything from basement stairs to exterior wall framing.

  2. Framing & Insulation
    – Our crew installs studs, joists, and bottom plates for a strong foundation. We then add insulation—rigid foam or fiberglass—for comfort and efficiency.

  3. Moisture & Waterproofing
    – Before drywalling, we address any moisture problems with waterproofing, mold resistant materials, and drainage solutions to protect your investment.

  4. Drywalling & Ceilings
    – We install drywall walls and ceilings, with options for drywall ceilings or drop ceilings. Every seam and joint is finished for a polished look.

  5. Flooring Installation
    – From concrete floors to subflooring and LVP, we handle every flooring installation with precision.

  6. Electrical, HVAC & Finishing Touches
    – Our team installs lighting, outlets, HVAC ductwork, and final details like trim, paint, and fixtures.

With a proven system and attention to detail, we make sure your basement remodel is seamless from start to finish.
