Quality Replacement Windows & Door Specialists


Covid-19 – Lockdown November 2020

During Lockdown 2 we are remaining open for business and installations strictly within the governments guidelines although our showroom is closed from Wednesday 4th until the lockdown is lifted.

Our suppliers are still manufacturing although their lead times are even more extended and they are also all suffering supply chain issues that are causing them to miss deliveries to us.

Please do contact us by telephone on 020 8648 0426 or email on office@sciwindows.co.uk and we will respond to you as soon as we can.

The health and safety of our staff and customers is paramount at this time and we hope you all remain safe and well through this period. Thank you for your ongoing support.
