Rotten Wood Replacement (PVC Upgrade)

Rotten wood spreads quickly and compromises your home’s structure. We identify damaged areas and replace them with maintenance-free PVC, ensuring long-term protection.

PVC never rots, warps, or absorbs moisture, making it the best solution for trim, soffits, window frames, deck components, and exterior architectural elements.

We install, repair, and replace:

  • Vinyl siding

  • Composite siding

  • Cedar & wood siding

Properly installed siding improves insulation, increases home value, and protects against water and wind damage.

  • Cedar

  • Composite materials (Trex®, TimberTech®, Fiberon®)
