Rankings are based on review rating and review count from public business listings, with a small lift given to businesses that show a working website and contactable phone number. We check each business's homepage to confirm window installation work is what they primarily offer, keeping unrelated trades off the page, and we automatically remove any listing flagged as permanently closed. Businesses marked Trust Verified have gone through our full verification process, covering qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information; see our How We Verify page for details. Other businesses listed have not been independently verified by us, and their inclusion isn't an endorsement. Always carry out your own checks before hiring.
