Replacement Sash Windows
(Box Sash Windows)
Many of our customers like to keep their original boxes, but replace the wooden sash windows only with new double glazed sashes. We now offer this service and the double glazed units we use will be either argon or krypton gas filled with a planitherm coating, meaning your new sashes will be much warmer than drafty single glazed originals, as we also fit new draft proofing.
Although replacing the sashes alone does not give you as good a product as replacing the complete box, it gives you a much warmer solution for about half the cost of full replacements.
All our sash windows can be fitted from the inside, meaning no hefty scaffolding costs, even if you windows are high above ground!
