We provide a wealth of information on our website about timber windows, but we'd be happy to visit your home or arrange a call-back.

We have a no pressure approach to meeting our customers and we always send written quotations following a visit. We understand that these projects sometimes take a while to get off the ground and we know that our customers don't want to be hassled so we simply send the quotation and wait. Some customers come back within a week, others take a month or even a year and that's fine.

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

Bespoke Windows in Stromproof Casements in Teesside

These bespoke casement windows were designed to replicate those being replaced in a Grade II Listed manor house conversion.

The top-opening Stormproof casement over a side-opening flush casement with equal sight-lines and Georgian bars created a near perfect replacement for the windows being removed - all with the benefit and double-glazing and improved security.

Mock Sash Windows near Darlington

This property, near Darlington, was fitted with our Mock Sash Dual Turn window, which bears a close resemblance to a sash window with the top sash fully in-front of the lower sash but the opening lights push outwards on reversible hinges.

The windows are made from FSC-Certified engineered Redwood and factory finished in Gardenia - a slightly cream shade of white.

Simple Flush Casement

This window is a hardwood Flush Casement window which is installed into a 25-year-old property designed along Northern European principles of clean-lines and maximum glass area.

This window is available as a top-hung opening sash or top-hung fully-reversible window which has the advantage of being able to be cleaned from inside.
