Our Services

For a home to be truly energy-efficient, it must have energy-efficient window solutions installed. Our double glaze upgrade service is designed to radically improve your original windows and make them energy efficient.

We offer the latest energy-efficient double glazing on the market today, at competitive prices. We can install your choice of double glazing into your original sash windows.



We offer two choices for installing double glazing

1: We can retain your original sash windows by removing the old glass and install slim double glazing into the sash windows. The sash windows and case are then fully renovated, painted, mastic applied and fully draught proofed.

2: We can replace the sash windows with new double glazed sashes to match your existing sashes and install these into the existing box (case). The sash windows and case are then fully renovated, painted, mastic applied and fully draught proofed.

Warmth is a valuable commodity and creating a second barrier to the elements is
an ideal way to reduce wasteful thermal heat loss. In fact, there are few better ways.

Advantages Of Energy Efficient Double Glazing

  • More comfortable home: energy efficient glazing reduces heat loss through windows and means fewer draughts and cold spots.
  • Peace and quiet: as well as keeping the heat in, energy efficient windows insulate your home against external noise.
  • Reduced condensation: energy efficient glazing reduces condensation build up on the inside of windows.

Better Thermal Insulation

Single glazed windows only offer limited insulation, while double glazing provides better thermal insulation, reduces energy bills and makes your home feel much warmer
