Traditional Timber Window Specialists
Many period homes across North London still retain their original timber sash windows, which were designed to last for generations when properly maintained.
Our restoration process preserves the craftsmanship of these original windows while addressing common issues such as:
- Rotten timber
- Sticking windows
- Broken sash cords
- Loose joints
- Water ingress
- Excessive draughts
- External noise
- Rattling sashes
- Flaking paint
- Broken glazing
By restoring rather than replacing, homeowners can retain the authentic appearance of their property whilst often complying with conservation area requirements.
Sash Window Draught Proofing
One of the most popular services we provide is professional draught proofing.
Older sash windows often allow cold air to enter through worn gaps between the sash and frame. Our discreet draught-proofing system significantly reduces heat loss without altering the traditional appearance of the window.
Benefits include:
- Improved energy efficiency
- Lower heating bills
- Reduced outside noise
- Less dust ingress
- Smoother window operation
- Reduced rattling
- Greater comfort throughout the year
Many customers notice an immediate improvement in room temperature after restoration and draught proofing.
Timber Repairs Instead of Window Replacement
Original timber sash windows were manufactured using high-quality slow-grown timber, which is often superior to many modern alternatives.
Rather than replacing entire windows, we carefully remove decayed sections and splice in new timber, preserving as much of the original material as possible.
This approach:
- Saves money
- Maintains period authenticity
- Reduces waste
- Extends window lifespan
- Preserves property value
Where appropriate, repairs are completed using durable hardwoods and high-performance fillers designed for long-term performance.
Sash Cord Replacement
Broken sash cords are one of the most common causes of windows becoming difficult or impossible to open.
We replace worn or snapped sash cords using high-quality traditional sash cord, rebalance the weights and ensure smooth, effortless operation.
Correct balancing also helps reduce unnecessary wear on the window mechanisms.
Restoration for Listed Buildings and Conservation Areas
North London contains many listed buildings and conservation areas where maintaining original architectural features is essential.
Our craftsmen regularly restore windows in heritage properties while respecting the original design and construction.
Where planning restrictions apply, restoration is often the preferred option over replacement, helping homeowners preserve both compliance and character.
Our Restoration Process
Every sash window restoration project follows a careful process:
- Full window inspection
- Assessment of timber condition
- Safe removal of sashes where required
- Timber repairs and splicing
- Replacement of cords and hardware
- Draught proofing installation
- Rebalancing and adjustment
- Final testing
- Finishing preparation
This ensures every restored window operates smoothly and continues to perform for many years.

Why Restore Instead of Replace?
Many homeowners assume replacement windows are the only solution for ageing timber sash windows. In reality, professionally restored original windows often last for decades with routine maintenance.
Restoration offers numerous advantages:
- Retains original character
- More cost-effective than replacement
- Environmentally friendly
- Improves thermal performance
- Enhances property value
- Maintains heritage features

Where the existing timber remains structurally sound, restoration is almost always the preferred option.
