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

Replacement Wooden Casement Windows in Tyneside

These replacement Flush casement windows are fitted into the original stone mullions and are a very close match to the old single glazed windows.

Replacement Wooden Casement Windows

The new windows are double-glazed with the original stained glass restored and encapsulated inside.

Replacement Wooden Windows with Stained Glass

Ancient Stone Cottage in Jarrow, South Tyneside

This Grade II Listed property was undergoing extensive refurbishment and needed new timber windows to fit between the stone mullions. The trouble was the sandstone mullions were too old and weak to take any new windows, so new mullions had to be installed by the builder.

Once these were in, we could fit our new windows - engineered softwood casement windows with Heritage slim double-glazing putty-glazed into solid through-bars. The finish was dual-colour with white to the inside to reflect light, and a pale blue outside.

Stormproof Casement Bay Window In Jesmond, Newcastle

Our task with this installation was to replace the upstairs bay window with one that closely matched the ground floor bay, installed a few years by others. Careful, precise measurement of the bay windows and the angles between them is the key to a successful bay window like this.

We specified 12mm antiqued lead diamonds for the windows which comprised 4 opening sashes and 6 fixed sashes. This photo illustrates the benefits of having fixed- or dummy sashes where the window doesn't open - direct-glazed frames would have looked completely unbalanced and at odds with the opening lights alongside.

Double Glazed Windows In Converted Chapel

A converted chapel near Newcastle-upon-Tyne needed new double-glazed timber windows each one shaped to the original stone arch. Ventilation was provided by a top-hung opening sash in the lower third of each window. We made these from engineered Redwood, finished in a rich translucent stain coating.

Timber casement windows such as these still demand quite a lot of skilled joinery work to create the individual arches from a template taken on site. The arch is made from a series of straight pieced individually machined and hand-jointed which are then shaped by hand and eye by a skilled and experienced craftsman in the joinery shop.

Timber Sash Windows installed in Jesmond, Newcastle upon Tyne

We recently completed the installation of timber sash windows to this delightful property in Jesmond, Newcastle. The house which is approximately 100 years old sits within a row of generously proportioned town houses complete with high ceilings and large windows.

Our client wanted to retain the period features of the property whilst gaining from double-glazing and weather-proofing. Our timber sash windows were a perfect match for the property and the result is excellent.

Inside, polished chrome hook lifts and fitch fasteners give a modern twist to the traditional sash look whilst the improvement in insulation and noise reduction is very apparent.
