Sash Windows Replacement Guide

In a lot of older or period style homes, such as Victorian / Edwardian and Georgian very often feature timber sash windows.  That’s not to say sash windows are exclusive to this type of property, as many terraced houses built in the 1950’s  & 1960’s also had timber sash windows.

The general problem with timber sash windows that have not been properly looked after is that the sash ropes break, the windows jam or get loose. Jammed windows obviously wont’ open & loose windows create draughts. On top of that, the majority will have originally been fitted with single glazing.

So it’s not surprising that so many homeowners are looking to replace their sash windows with something else.

What style to replace a Sash window with?

Cost of Double GlazingWell, theoretically, you could use any style of replacement window, but before you rush off to buy some new windows, take a while to consider some things.

  1. will the new style of window suit the property / or make your house look too different to the surrounding properties and make it less attractive?
  2. Are there any local restrictions, such as your home being a listed property or situated in an area of outstanding natural beauty (ANOB).
  3. Are you allowed to use UPVC or Aluminium locally or are you facing some restrictions locally.

You may not be aware of any local restrictions about replacement windows, so check with your local authority first if you are planning to change the style to something else.

Other styles, such as casement windows have much slimmer frames that Sash designs. What that means for you when switching from sash to casement is that there will be a lot more internal making good on the window cills, heads and reveals.  That also means you have to pay for extra labour & materials.

However, these extra labour costs can be offset by the much lower cost of casement widows compared to sash designs.
