We offer a complete range of doors for the home, both internal and external.

Hardwood Conservatories

When you step inside your conservatory from Firth UK you enter the exclusive world of the hand built bespoke conservatory. You cannot fail to appreciate the quality of the craftsmanship and the depth of finish of our hardwood conservatories. All Conservatories are unique and all are built to the very highest standards specifically for you, providing the perfect link between your house and garden.

Wooden Windows

Well designed quality wooden windows can enhance a property and increase its value substantially, making it into an even more attractive and desirable home. They give light and life to the façade and functional style to the overall design. However, poor quality or inappropriate designs can seriously detract from a buildings appeal and value.

Here at Firth (UK) we have over 75 years of designing and manufacturing top quality new and replacement windows. Our range of hardwood and softwood windows are guaranteed to provide the style, functionality and high standards you require. They are both an investment and an intelligent choice when it comes to the best for your home and the Planet’s future.

Standard or Bespoke Frames:

We can provide windows from a stylish set range of Premier Frames to suit your property – or provide a fully bespoke design and fit service to create almost any size, shape or construction of window you or your architect can imagine. We like a challenge! Your requirements may be for an individual windows or a full set of windows – to either replace or match your old windows, or to an enhanced design to add to your home.

Complete Service:

We can assist you right from the design stage and will visit you to carry out an initial survey and quote. We are craftsmen, not salesmen and we will not push you into anything you do not want or need. Once you have placed an order we carry out a full site survey, manufacture your windows and deliver to your home with our skilled and experienced fitters. If you wish to use your own fitters we will just arrange delivery.

We can also liaise with your architect and local planning office directly. Compliance with the latest building regulations is assured as all our windows have high thermal efficiency and longevity as standard. If your property is in a Conservation Area or is a Listed Building we can also assist with the application to your local planning office.
