MADE TO MEASURE
FOR A WARMER WELCOME

Doors

From composite doors in eye-catching colours and contemporary bi-folding styles that maximise on space, to hardwearing, low-maintenance PVC-U; each and every Sierra door is made to measure, so it’s guaranteed to keep the sound out and the warmth in.

Sierra doors are independently tested to ensure they comply with (and often exceed) industry standards. They are thermally efficient, high quality and available in a range of sizes, colours and with a choice of threshold. We can even manufacture your door to meet the requirements of the police-backed initiative, Secure by Design.

Sierra offers you a complete design to doorstep service, with an exceptional attention to detail at every stage. If you’re searching for a supplier that can make your job as straightforward as possible, please contact our team today.
