A SASH WINDOW WIZARD Menu

Our double glazing service provides new purpose-made double glazed sashes in either treated redwood, hardwood or Accoya, fitted into your existing box frames. Double glazing brings many benefits, including: improved draught proofing, better heat retention, noise reduction, improved security, giving the look of a new window without the cost.

At the same time this service allows you to retain your original box frame and architraves.

We believe our new double glazed sashes fitted into box frame service is the most comprehensive within the market. Fully painted using micro-porous paints you can be sure of a window that will withstand all that the British weather can throw at it.

Sashes are constructed to match the original design as closely as possible and we have many glazing options including safety/security glass, acoustic glass, low e, or obscure patterned glass.

Old sashes, weights and beads are disposed of and the original box frame is burnt back and sanded as necessary to prepare for painting.

We use white micro porous paints to undercoat and fully gloss the complete box frame inside and out, ready to accept the new spray finished sashes. New sashes are installed into the windows with our weather pile draught proofing system and new lead weights to counter balance the much heavier double glazed sashes.

A full set of fittings is installed in your choice of finish and the box frame receives a final coat of paint, leaving you with a fully finished product!
