Rotten Sash Window Repairs
in Eastbourne Hastings and East Sussex

Rotten sash windows do not always need to be replaced.
In many older timber windows, the rot is localised.
That means the damaged section can often be cut out and repaired, while keeping the original sash window in place.
At RWJ Sear Restorative Carpentry, I repair rotten sash windows in Eastbourne and across East Sussex, using traditional timber repair methods wherever possible.

The Problem
Rot is one of the most common problems with old timber sash windows.
It often starts quietly. A small soft patch appears in the timber. Paint begins to blister or crack. Water gets in. Over time, the damage spreads.
Many people are told that the whole window needs replacing. In many cases, that is not true.
A rotten sash window may only need a careful timber repair to the damaged area.

Common Signs of Rotten Sash Windows

You may need this repair if:

• The timber feels soft

• Paint is bubbling, flaking, or cracking

• The bottom rail of the sash is rotten

• The lower corners of the sash are damaged

• The sill or cill is soft or breaking up

• The window frame has visible decay

• The sash feels loose or weak

• Water has been getting into the window

• Previous filler repairs are falling out

• The window sticks, drops, or will not close properly

• The glass or putty has failed around the rotten area

• You can push a screwdriver into the timber

Rotten timber should not be ignored. The longer water is allowed to get in, the more damage it can cause.

Why Sash Windows Rot

Timber sash windows usually rot because water has been allowed to sit in or enter the wood.

Common causes include:

• Failed paintwork
  Cracked or missing putty

• Open joints

• Poor previous repairs

• Filler used instead of proper timber repairs

• Water sitting on the sill or lower rail

• Blocked drainage

• Damp masonry around the window

• Lack of maintenance over many years

• Modern materials trapping moisture in old timber

Rot is not always a sign that the whole window has failed. Often, the rest of the window is still sound.

What I Do

I inspect the sash window and identify how far the rot has spread.

Depending on the condition of the window, the work may include:

• Cutting out rotten timber

• Cleaning back to sound wood

• Making new timber repair sections

• Splicing in new timber

• Repairing sash corners

• Repairing bottom rails

• Repairing rotten sills or cills

• Repairing damaged box frames

• Removing failed filler repairs

• Re-securing loose joints

• Replacing failed putty where needed

• Preparing the repair for painting

• Making the sash window solid and usable again

The aim is to remove the decay, save as much original timber as possible, and repair the window properly.

Repair, Not Replacement

A rotten sash window does not automatically need to be replaced.

Older timber sash windows were built to be repaired. Many contain good-quality timber that is far better than much of what is used in modern replacement windows.

If the rot is localised, the damaged section can often be cut out and replaced with new timber. This keeps the character of the original window and avoids unnecessary replacement.

Repairing the original window is often the better choice for older houses, period properties, listed buildings, and conservation areas.

Traditional Timber Repairs

I use traditional repair methods wherever possible.

That means cutting out the rotten timber and replacing it with properly fitted timber sections, rather than simply filling over the problem.

Filler may hide rot for a short time, but it does not cure the cause.
A proper timber repair gives the window strength again and helps it last.
