Replacement Pocket vs. Full-Frame Windows

Replacement windows are available as pocket or full-frame windows and are designed so that the installer does not have to remove any exterior materials of a home including the siding and exterior cladding. Pocket replacement windows are installed into a pre-existing window frame from the inside of the home whereas full-frame replacement windows completely replace the window frame and will adequately flash the opening.

Why Replacement Windows from MHx?

  • Energy Efficiency. Combining advanced materials with modern manufacturing techniques, our windows keep your home warmer in the winter and cooler in the summer.
  • Low Maintenance. Our windows are made of long-lasting materials that retain their shape, color, and strength, and never need to be scraped or painted.
  • Easy Cleaning Access. We install replacement windows featuring tilt-in sashes for convenient cleaning, both inside and out.
  • Improved Curb Appeal. An expansive glass area and an attractively finished frame make our windows a beautiful new addition to your home.
