Draught Proofing for Sash Windows
Draught Proofing – Original timber sash windows bring timeless character to your home—but they’re not always known for energy efficiency. Over time, natural movement, paint build-up, and ageing frames can cause gaps that let in cold air and outside noise.
Invisible protection. Noticeable comfort.
At Cavendish & Cole, we offer specialist draught proofing for sash windows—a discreet, effective upgrade that significantly reduces heat loss, rattling, and external noise while preserving the beauty of your existing joinery.
Whether your home is a Georgian townhouse, a Victorian terrace, or a listed property, we provide a tailored service that respects tradition while improving comfort.
Why Draught Proof Your Sash Windows?
- Reduce heat loss and improve insulation
- Stop rattling windows and improve smooth operation
- Cut down on dust, noise, and airborne pollutants
- Improve energy efficiency without replacing your windows
- Maintain the look and feel of your period home
- Potential to lower energy bills
Our draught proofing system is nearly invisible to the eye, but the difference in comfort is immediate.
What’s Included in Our Draught Proofing Service?
We don’t just add seals—we fully assess the condition of your windows and carry out precision work to ensure optimal results.
- Removal and inspection of existing sashes
- Trimming, realigning, and easing for smooth movement
- Installation of high-quality brush seals and carriers in key contact points
- Refitting of sash cords, pulleys, and weights (if needed)
- Optional Slimlite glazing upgrades for improved insulation
- Full repainting and finishing for a clean, professional look
All work is completed by our experienced, in-house team at your property or via our Sussex joinery workshop.
Heritage-Friendly Insulation
Our draught proofing techniques are widely accepted by conservation officers and local authorities—even in listed buildings and conservation areas. That’s because our system is:
- Non-invasive and fully reversible
- Hidden within staff and parting beads
- Compatible with original or restored sashes
- Ideal for use alongside Slimlite double glazing and Accoya timber upgrades
We can also provide supporting documentation or liaise with your planning authority if required.
Combine with Sash Repairs or Glazing Upgrades
Draught proofing is often most effective when combined with general maintenance or glazing improvements. We frequently include it in:
- Sash restoration projects
- Single to double glazed upgrades
- Full sash replacements using traditional profiles
- Acoustic or patterned glazing installations
We’ll advise on the best package based on your windows’ current condition and your goals for comfort, efficiency, and preservation.
