Curved Triple Bay Sash Window Restoration
Repair, not replace – preserving the character and performance of historic windows.
Window Restoration and Repair Services in Essex
HarriDec Ltd specialises in restoring original timber windows for period and listed properties across Essex and East London. Our philosophy is simple: preserve, upgrade and extend the life of the windows you already have. Using traditional craftsmanship combined with advanced repair systems, we save historic windows that many would prematurely replace.
- Property: Period homes, listed buildings, conservation area properties
- Location: Essex and East London
- Building date: Georgian sash windows, Victorian casements, leaded windows and heritage frames
- Project completed: Repair, retain and upgrade original windows rather than replace
Why Restoration is Better Than Replacement
Historic England and SPAB endorse repair over replacement because original timber windows were built from far superior materials than most modern equivalents. With skilled restoration, over 85% of original windows can be saved.
Key advantages of repairing:
- Cost savings: Restoration is often a fraction of the cost of manufacturing bespoke new units.
- Heritage preservation: You keep the original glass, sightlines and craftsmanship that define your home’s character.
- No planning permission: Repairs rarely require conservation consent, unlike full replacements.
- Eco friendly: Avoids landfill waste and the carbon footprint of manufacturing new windows.
- Long lasting: Hardwood splicing, linseed putty and resin systems extend window lifespan for decades.
Restoration maintains authenticity while upgrading performance and saving homeowners significant expense.
Common Issues in Older Windows – And Our Solutions
Traditional windows often suffer from decay, drafts or failing paint, but nearly all these issues can be cured without replacing the window.
Typical problems we repair:
- Rot and decay in sills, frames and glazing bars
- Drafts and rattling due to gaps or poor fit
- Stuck or painted shut sashes
- Failed putty and cracked panes
- Peeling paint and weathered timber
We restore these issues through careful timber repairs, draught-proofing, re-cording, glazing upgrades and breathable repainting. The result is an authentic window that works like new.
Resin Joinery Repairs and Sash Window Refurbishment
HarriDec is trained and certified in the Repair Care epoxy resin system, approved for use on historic buildings. This allows us to remove localised rot and rebuild damaged timber in place, without removing the window or replacing entire components.
Repair Care Method:
- Remove all decayed wood
- Stabilise the remaining timber with epoxy primer
- Rebuild missing sections using Dry Flex resin or spliced hardwood
- Sand and repaint to match seamlessly
These repairs are flexible, durable and backed by a 10 year guarantee.
Sash Window Refurbishment Includes:
- Replacing sash cords and servicing pulleys
- Freeing stuck sashes and balancing the weights
- Installing discreet draught-proofing brush seals
- Re seating glass in linseed putty
- Strengthening weak joints and repairing glazing bars
After restoration, sash windows slide smoothly, stay open safely and provide dramatically improved comfort and energy efficiency.
Glazing Repairs and Sensitive Upgrades
- Replacing cracked panes with restoration glass that matches the historic appearance
- Re bedding loose panes using traditional linseed oil putty
- Renewing glazing sprigs and repair leads for leaded windows
- Offering optional secondary glazing for thermal improvement where allowed
- Advising on ultra thin heritage double glazing where appropriate
