Expert Sash Window Repairs
Restore the charm. Retain the character. Improve the performance.
Sash windows are a defining feature of many Georgian, Victorian, and Edwardian homes—but over time, they can become worn, draughty, or difficult to operate. At Cavendish & Cole, we offer specialist sash window repair services designed to bring your original timber windows back to life.
Whether it’s sash cord repair, rot restoration, or a full draught-proofing upgrade, our expert team works with precision, care, and deep respect for your property’s heritage.
We serve homeowners across Sussex, Kent, and Surrey, with all work carried out by our skilled, in-house craftsmen.
Common Sash Window Issues We Repair
- Broken sash cords or jammed windows
- Rattling panes and excessive draughts
- Timber decay or rot in sills, sashes or frames
- Flaking paint or damaged putty
- Ill-fitting windows or distorted sashes
- Glazing upgrades, including single to double glazed conversions
No matter how minor or extensive the damage, we provide honest assessments and tailored solutions—always aiming to preserve original features wherever possible.
Our Sash Repair Services
Sash Cord Replacement
Over time, cords can fray, snap or lose tension. We replace worn cords with high-grade sash cords and check all pulleys and weights to ensure smooth, balanced operation.Draught-Proofing Upgrades
Reduce heat loss and rattling without replacing your windows. We install discreet draught-proofing brushes and seals that are barely visible but make a noticeable difference in comfort and energy efficiency.
Timber Rot Repairs
Using traditional joinery methods and sustainable materials like Accoya, we carefully remove decayed sections and splice in new timber, restoring both strength and integrity.
Glazing Repairs & Upgrades
From broken panes to Slimlite double glazing upgrades, we can replace or reglaze your sash windows while keeping your home’s character intact. Ideal for listed buildings and conservation areas.
Surface Restoration & Repainting
We’ll strip back flaking paint, repair putty lines, and professionally repaint with breathable, weather-resistant finishes for long-lasting protection.
Why Repair Instead of Replace?
Wherever possible, we recommend repairing rather than replacing sash windows. Repairs are:
- More sustainable and environmentally friendly
- Often more cost-effective
- Ideal for maintaining the original character of your property
- Preferred by many conservation officers and heritage bodies
- Quicker than full replacement
- Fully compatible with upgrades like Slimlite glazing, draught-proofing, and security enhancements
