Signs You May Need a Replacement Sash
Some of the most common reasons for replacing your sash window include timber decay and moisture damage.
Often, the bottom sash or lower box frame rots because of moisture penetration. As a result, the window becomes weak and difficult to operate. So, if you notice moisture penetration, do not leave it untreated. Otherwise, decay can spread to other parts of the window. Consequently, this leads to more costly repairs later on.
We get a lot of enquiries about replacement sash windows, window sill replacements, and sash window repairs throughout South East London. This includes Greenwich, Lewisham, Bromley, and Blackheath. Below are common signs that your bottom sash, window sill, or box frame may need attention:
- Rotten timber on the bottom rail of the lower sash
- Rotting, cracked, or broken meeting rails
- Loose, damaged, or missing glazing bars
- Sash windows that are difficult to open or close
- Water ingress, draughts, or condensation issues
- Weakened, cracked, or split timber sections
- A rotten, soft, or damaged window sill
- Rotting outer linings or lower sections of the box frame
Our experienced window surveyors can assess the condition of your sash windows. Then, they will advise whether a targeted repair or a complete sash replacement offers the most cost-effective solution.

Can Sash Windows Be Repaired Instead?
Not all sash windows need replacing. In fact, minor issues such as broken cords, draughty windows, damaged putty, or isolated timber repairs can often be fixed.
Is it cheaper to repair or replace a sash window?
Generally, repairing is cheaper where the damage is isolated. For example, our sash window repair specialists can splice in a new hardwood timber sill to replace a rotten one. This typically costs between £180 and £280 for the average window. However, if the frame has significant rot, or repeated repairs have failed, a new installation is usually more economical in the long run.
How much does it cost to repair a sash window sill?
A hardwood timber sill splice repair typically costs between £180 and £280 per window. This depends on the extent of the damage and access.
When should I replace a sash window instead of repairing it?
If the frame has significant rot, or if repeated repairs have failed, replacement is usually best. Similarly, if the box frame itself is compromised, replacing the bottom sash or the full window tends to be the more cost-effective long-term solution.
Sash Window Replacement Cost
If only the lower sash is damaged, rotten, or beyond repair, replacing it is often the better option. In most cases, this is more cost-effective than replacing the entire window frame.
Typically, the cost of replacing a bottom sash ranges from £420 to £740. This depends on the factors below.
| Cost Factor | Details |
|---|---|
| Window size | Larger sashes require more materials and labour |
| Glazing type | Single glazing or double glazing |
| Glazing bars | Number and style of glazing bars |
| Timber & moulding | Timber type and moulding detail |
| Building status | Listed building or conservation area requirements |
| Finishing | Painting and finishing requirements |
Overall, every replacement sash window is manufactured to match the original design, proportions, glazing bars, and period detailing of your existing timber windows.
