1st Sash Windows Shop front

1st Sash Windows is a family run business; with over 50 years’ experience between the owners Robert and Marvin in all aspects of windows doors and conservatories.

Furthermore across the fitting teams there’s a further 70 years plus experience, so you can see we have plenty of experience across the company as a whole.

We do not just specialise in one type of window, we supply and fit wooden Sash windows, doors and casements, and conservatories and aluminium windows which means we have no “Axe” to grind either way with one product over the other. As a result of this we are able to give you an unbiased assessment of the work needed on your property and provide you with an honest, free, no obligation quote for the work.

We have our own workshop to manufacture our own bespoke wooden sash windows and doors which mean our prices for all new joinery are very competitive and we are able to control the quality of the work from start to finish insuring a high standard job.

At 1st Sash Windows we are proud member of Certass. Members of the Certass Competent Person Scheme are able to self-certify that our installations adhere to current Building Regulations as an alternative to submitting a building notice to the local authority or using an approved inspector.
