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.

Thank you both
