Sash Window Repairs and Restoration

Traditional wooden box sash windows look great and are extremely durable. With a small amount of general maintenance, when needed, they can withstand the elements and the test of time.

However missing putty, open joints and gaps around the perimeter of sash windows and flaking paint can lead to moisture intake and wood decay. That's where London Box Sash Windows can help.

Sash Window Repairs vs. Replacement

We often find that many of our customers are surprised when we present the option of repairing decaying windows rather than replacing them.

Many of the calls we receive are from people who have been advised that they need new box sash window replacements. In the majority of these cases sash window restoration or repairs are possible and will be equally effective.

Sash window restoration or repairs should always be considered as the first option. Only if the boxes or the sashes have deteriorated beyond repair should replacement be considered. The reasons for this are simple: old Victorian and Georgian sashes were made using far superior quality timber than the timber used in modern day joinery; rotting woodwork found in sills, lower areas of box frames and sashes is common and we can often apply a high quality resin repair, carry out a timber splice, or replace only certain components of the window framework and finally sash window repairs ALWAYS cost less than sash window replacement. Windows can be very successfully repaired for far less than the cost of full sash window replacements.

London Box Sash Windows attitude is to always try and retain as much of the original, good quality timber as possible.


London Box Sash Windows will carefully examine frames and sashes to establish the extent of decay and to establish if repairs can be made rather than replacement.
