Restoration, draught-proof, Double Glazing

Scott James are experts in the sympathetic restoration and redecoration of a wide range of historic wooden windows.

Choosing us for your window restoration job means prioritising the original aesthetics of window units alongside a high-quality work approach that lovingly brings them back to their intended condition.

For projects of 30+ windows, we offer a trial refurbishment of 1 window.

Our window restoration Guarantees

Double-glazing for 15 (Manufacturer guarantee)

Repairs for 20 years (if any of our repairs produce faults, we’ll promptly come back to address the issues)

And with thoughtful maintenance and ongoing care, original windows can last well into the next century!


Whether Georgian sashes on a stately home through to small window units on a terraced Victorian property- our approach and dedication to quality is the same. We combine the best of modern window restoration methods with a strong respect for the original window design and construction, leaving an unrivalled finish.

Some of the issues our services address:

  • Rotting frames and sills
  • Poorly fitting windows causing problems with heat loss
  • Damaged glass window panes
  • Broken sash cords, springs, chains and pulleys
  • Tired and/or damaged paintwork across window units

Restoring rather than replacing wooden windows is often a cost-effective and sustainable way to retain your property’s architectural personality. 

Timber restoration

For our work, we only use the highest-quality materials. Combined with advanced epoxy resins, sealants and fillers, we replace complete sections of degraded timber using Accoya® timber and Tricoya® panelling and veneers. Working with the Accoya®/Tricoya® material range means that traditional styling and quality can be preserved. Enhanced durability and longevity are built in.

In most cases, our team of experts can repair and restore existing windows. By identifying the root causes of rot, decay and damage, we can take remedial action, resulting in 100% strong, fit-for-purpose, beautiful wooden sash windows – transforming your windows and property.

Double Glazing

We also carry out the retrofitting of new glazing into existing historic frames. For this process we use ultra-thin Fineo glass which allows for the original look to be maintained whilst offering significant improvements in thermal efficiency and security.


By carefully overhauling your sash windows and renewing, upgrading or adding high-quality draught-proofing, we can make large improvements to your window operation and thermal efficiency. Draught-proofing will reduce external noise, resolve rattles and prove a highly cost-effective way to enhance your home space.


Window decoration is the last stage of the restoration process but also something we carry out for clients as a standalone service. Whether box, sash or bay window, we are able to complete our redecoration work to extremely high standards.

During the restoration process, we employ our unique Accoya timber system with which even very damaged windows can be salvaged. With the wood’s 50 years above ground guarantee, combined with our 20 years offered on repairs and 10 years on paintwork, clients are left with confidence in the lasting durability of the work carried out by our teams.

Our expertise has been built up over the years carrying out a large range of restoration projects on domestic, heritage and commercial properties. This includes recent work on beautiful Grade II listed houses in Ramsden Heath, St. Ives and Sawbridgeworth where we dealt with historic windows in very poor condition administering full restoration and redecoration to bring them back to life.
