Your home security is only as strong as its weakest link

Secured by Design window solutions in the East Midlands

All our high-performance, secure window systems can be manufactured to Secured by Design specification. This is an independent police-approved group that was established as part of the Association of Chief Police Officers to evaluate the effectiveness of window products against crime.

In short, this means that the design of any window accredited by the scheme has met strict test criteria to ensure that it can withstand attack against forced entry.

Working with the Secured by Design specification allows us to offer secure external windows, so feeling unsafe at home or worrying about burglary when you’re away will become a distant memory with a superb Stormclad replacement window installation.

Neil Stacey

Had new door and side window. WOW, great quality, excellent fitters, Ben & Kyle. Had a guess at the price before a quote and they quoted £1000 less than I thought. The service, communication and professionalism of the company staff we encountered was 10/10 I would most definitely use Stormclad again.

We are very pleased with our new windows. Thank you to Andrjez and to Simon for discussions on the design and the survey – so helpful. The installation went really well so thanks for that to Jono and Ben, they were very efficient and also friendly and polite. I would definitely use Stormclad again in the future.

Even in a Covid world everything was done efficiently. Liaised with Dennis over email to save a visit for the initial paperwork, Simon came around for the measuring up and then once again (on request) we had Jono and Ben for the installation. Fitted in half the time quoted, fantastic attention to detail and exactly as we hoped for. Our second time using Stormclad and both experiences have been excellent.
