Why would a sash window require repair?

Sash windows are constructed from several different pieces of timber. Any one of these sections could become decayed and would require repair or sectional replacement. Leaving these sections unresolved could cause long term decay to surrounding sections and lead to a situation where replacement of the entire window is the most economical solution. At Fortis & Hooke we believe that replacement of a original window is the last option. Therefore, we’ve created cost effective ways to repair or replace decayed sections by combining modern technology with good old carpentry skills. Our aim with these repairs are to ensure that the problem is resolved permanently and thus provide the sash window owner with a long term solution, rather than a short term fix.

The following sections discuss particular areas of a window that we’ve found to be prone to decay.

Sill repair or replacement

The sash window sill tends to first show signs of decay. The sill is the bottom section of the sash window. It is where most water lies and, subsequently, this causes the paint to flake – effectively opening up areas where water can penetrate the timber and cause decay.

Water marks beneath your sash window is a tell-tale sign of a rotten sill. These watermarks are usually caused by an opening between the timber sill and the masonry sill. This “opening” could just be due to bad sealing, but could also have been caused by decay.

A rotten sill does is not necessarily a cue for full window replacement. At Fortis & Hooke we can repair or replace any sash window sill with a new hardwood section. This will resolve the sill problem and leave you with a solid foundation for your sash window.

Bottom rail repair or replacement

The sash window bottom rail is one of the sections of a sash window that could develop decay due to bad maintenance. The bottom rail is the bottom section of the bottom opener on a sash window. Due to superfluous putty or internal condensation water could saturate into any open timber on the bottom rail. This saturation of water would cause decay.

A rotten bottom rail is not a cue for full window replacement. At Fortis & Hooke we prefer to repair or replace a bottom rail with a new hardwood section. This will resolve the problem and prevent the replacement of the entire bottom sash.

Middle rail repair or replacement

The sash window middle rail is another section of a sash window that could show decay due to bad maintenance. The middle rail is the bottom section of the top opener on a sash window. The same issues that bottom rails suffer are also prevalent on middle rails. Due to superfluous putty or internal condensation water tends to saturate into any open timber on the middle rail. Due to the saturation into the timber there could be sectional decay in a middle rail.

However, as with a bottom rail, a rotten middle rail is not a cue for replacement of the entire window.

At Fortis & Hooke we would repair or replace a decayed middle rail with a new hardwood section. This would resolve the issue and prevent unnecessary replacement of the entire top sash.

Frame repair

The last section of a sash window that could need a repair is the sash window frame.

The frame mostly shows some decay where it meets with the sill. Sometimes there is a tear between the sill and the frame, which causes water ingress and subsequent decay.

This type of repair is usually very small and can be resolved easily.

Glass replacement

At Fortis & Hooke we offer a wide range of glass replacement services. These services range from normal glass replacement to the installation of special glass, i.e. sound reduction glass.

We also offer a double glazing option where we can retrofit new double glazing into existing sashes.

Broken down putty

Broken down glazing putty is a major contributing factor to rotten sash windows. Putty ensures that the glass and open timber rebates are sealed properly to protect against water ingress. Should a gap develop, water ingress would potentially lead to rotten sections.

It is therefore essential that your window putty is checked and maintained to ensure it is doing what it is supposed to.

Construction joint tearing

All sash windows have construction joints. These joints tend to separate leading to water ingress and resulting in paint breakdown and rot.

It is essential that your window joints are checked and repaired to ensure that they are not providing an entry point for moisture.

The aforementioned services are all available on request.
