Sash Window Companies Are Not All Expert

The owner had sensibly invited several sash window restoration companies to quote for the work required. Whilst other ‘sash window experts’ could only offer to completely replace the existing window, Sash Window Specialist really are experts at repairing heritage windows.   Replacing a bay window always remains our last option.

With our period window repair service we preserve all of the original Victorian moulding detail, typically found around the head of period bay windows. These fine details are architecturally significant and would have been sacrificed by the replacement windows being offered.

Period Window Restoration

As the wood rot was all contained around the window sill area we knew this traditional window frame could be repaired and saved.

Firstly, we had to remove all the rotten timber, including all three of the window sills.  Once the rot was removed we could start to rebuild the bay window frame. 

Replacement hardwood window sills were produced at our workshop, copying the same profile as the originals.  These were jointed on-site to ensure they followed the existing brickwork.

Next the box sash window frames were repaired.  By splicing in Accoya wood we ensure that the repairs will last a lifetime.  Accoya wood will not rot for at least 50 years.  The joints between the splice and the original frame are glued with epoxy for a permanent water tight bond.

Double Glazed Sash Windows

Replacement double glazed timber sash frames were made at our sash window workshop in Reading, Berkshire.  We produce authentic replicas of the originals by paying close attention to accurately copying the mouldings and sash horn shapes.  Accoya wood was again selected for exceptional durability

Factory fitted with low-e double glazed units and paint finished, to minimise the work required on-site.  Low-e glazing units incorporate Pilkington K glass and are filled with Argon gas for improved energy efficiency.

How Much Does A Bay Sash Window Restoration Cost?

The restoration of this Victorian bay window was much cheaper than the replacement windows offered by other sash window companies.

Every window restoration is different and we price them on a case by case basis.  The thickness of the timber required, glazing patterns and accessibility all contribute to our costs.
