Below you'll find a selection of work we have undertaken in the Sheffield area, supplying and fitting timber windows.





Casement Windows Bakewell, near Sheffield

This wooden windows installation was in Froggat in the Peak District, close to Hathersage, Bakewell and Sheffield.

Traditional timber flush casement windows replaced the old windows, and are finished in a dual colour - Pure White inside and Minerva Grey outside.

These casement windows are A-rated with multi-point locking and a 30 year warranty against rot.




Stunning Grade II Georgian Property in Hillsborough

This 18th Century grade II listed Georgian style building situated in Sheffield is of the oldest in the area. When it was first converted into spacious apartments, only 10 years earlier, poor quality, single glazed softwood sash windows were installed and they were already leaking and suffering from rot. Our brief was to replace these like-for-like but to as high a specification as the local Building Conservation Officers would allow.

So we turned to our partners at George Barnsdale to supply the very best sash windows with traditional pulleys, weights and cords, narrow solid glazing bars and individual panes of 'Heritage' double-glazed units fixed with butyl putty. The windows were made in Grandis hardwood with accoya linings.

Naturally, Listed Building Consent had so be sought, for which we supplied scale drawings of the windows but the installation itself went very well indeed. What a lovely job.




Cold Steel to Warm Wooden Windows

Here's a great example of replicating existing styles whilst massively improving thermal efficiency.

The original windows in this house near Sheffield were steel frames in a timber subframe with all the drawbacks that they present - cold, draughty, noisy and lots of condensation on the inside faces.

By replacing them with these timber flush casement windows the property retains its original charm, everything is in proportion and the house is significantly warmer, quieter and without the 'puddles' on the inside.

The finishing touches were provided by pewter-finish monkey-tail handles and stay arms. We can offer a wide variety of ironmongery on our wooden casement windows from contemporary designs to traditional-looking handles in a variety of different finishes.




New Wooden Bay Window in Sheffield

We were asked to replace these original timber sliding sash windows within a bay window of a terraced house in Sheffield. The whole of the bay window had seen better days and the roof felting had long-perished causing extensive water penetration and rot. This window had survived bombs in the Second World War that damaged other houses in the street and was one of the few remaining examples of the original joinery.

During the survey, it became apparent that it would be a slightly bigger task than simply the windows and roof. Although the bay was built on-top of a stone cill, none of the supporting timbers below the bay were intact and in effect the bay was hanging in fresh air, ready to drop into the cellar below at any moment.

New concrete supports were installed below the floor-level whilst a complete new internal timber frame was installed to support the internal cills and panelling. Meanwhile, after installing new timber sash windows, we replicated the detailed external mouldings, built a new flat roof, insulated and lined this with lead and replaced the guttering.

This bay window now sits proudly as the best in the street!




Oriel Windows, Sheffield and Northumberland

An oriel window is a form of bay window which protrudes from the main wall of a building but does not reach to the ground.

Here are two very different examples of this concept. The first was a simple like-for-like replacement in Sheffield taking out old uPVC windows and installing timber frames, complete with diamond leading, with a small corner-post in-between.

The second example was a brand new oriel window in-place of a flat window within the existing wall. Our customer had a rear garden on the banks of the lovely river Wansbeck near Morpeth. They wanted to be able to sit in the window and look up and down river, so we constructed this special window for them.

The window is supported by timber gallows brackets whilst the flat roof was covered with Sarnafil - a durable long-lasting waterproof material. The centre window is a flush casement hung on reversible hinges.
