Timber Sash Window Replacement in London

We specialise in sash window replacement across London, supplying and installing high-quality timber sash windows tailored to suit your property.

Each window is manufactured to match the original design, ensuring it complements the character of Victorian, Georgian, and period homes.

Our replacement sash windows include:

• Slimline double glazing (Low-E, argon-filled)

• Engineered hardwood timber (Sapele)

• Discreet draught proofing systems

• Traditional-style ironmongery with modern security

This allows you to upgrade insulation, security, and usability while maintaining a classic appearance.

Like-for-Like Sash Window Replacement

All replacement sash windows are made on a like-for-like basis, carefully replicating original proportions, glazing bars, and detailing.

This is especially important for:

• Conservation areas

• Listed properties

• Period homes across London

We ensure your new windows look authentic while delivering modern performance.

When Should Sash Windows Be Replaced?

While many sash windows can be repaired, replacement may be required when:

• Timber is severely decayed

• Frames are beyond repair

• Windows no longer operate safely

• Previous repairs have failed

We always assess your windows first and recommend replacement only where necessary.
