Our product range is extensive and includes box sash windows, flush casement windows, storm-proof casements, vertical sliding windows, front and back doors, French doors, folding doors, sliding doors, composite doors, window shutters, secondary glazing and bespoke conservatories. All our timber products are manufactured from the highest quality sustainable sources to your dimensions, and the finishes we use are all aimed at ensuring the maximum possible durability.

In addition to traditional replacement timber products, we are now able to supply a range of extremely high quality timber alternatives, including high thermal efficiency doors and windows and double-rebated doors. These are not typical 'old fashioned' and poor quality plastic products, but are manufactured to extremely high standards and incorporate the very latest technology, including seamless-welded joints. The technology really has moved on massively, and our timber-alternative products are all but indistinguishable from 'real' wood,

We are now also able to supply and fit a superb range of window shutters, designed to enhance the value and visual appeal of your home. All our products are available fitted by us, or can be supplied on site, and almost all are available in an almost infinite choice of paint or natural finishes. The secondary glazing units we supply and fit are incredibly high quality. Designed to be unobtrusive, they are an ideal fit for circumstances where replacement of existing windows or doors is unnecessary or uneconomical, but where improvements to noise reduction and sealing is desirable. Fitted internally, behind existing glazing, installation is straightforward and usually will not entail any need for subsequent redecoration. High quality secondary glazing is also ideal for listed buildings or property in conservation areas, as the existing external appearance remains unchanged, and planning permission is rarely required.

An established, family firm, we aim to source timber from FSC certified suppliers and to achieve a full chain of custody for the natural materials used in our timber products. In addition, we offer industry-leading guarantees for all our windows and doors. The timber alternative products we offer have been specifically chosen by us as some of the very best on the market and provide a perfect combination of extremely high quality and genuine value.
