Committed to quality

Our windows come in a wide range of styles, colours and finishes to suit every need. All our windows are manufactured in the UK using the highest quality components backed with high levels of certification. All of our installations, excluding replacement glass units and service or repair work to existing frames, carry the BSI Kitemark along with Assure Certification, ensuring they comply with the highest standards of workmanship and building regulations.

In safe hands

Rest assured your windows will be installed by our own salary-paid full-time fitters. We don’t use subcontractors (who are typically paid per window), ensuring our fitters have the time and resources to install to our exacting standards. Once the job is complete, you will be covered by a 10-year guarantee supported by our own in-house service engineer and all backed up by a QANW insurance policy.
