A note from our founder
Why we started Hollis & Grange Builders.
We opened our doors in York with a simple idea: customers deserve people who listen, explain things properly and treat every visit as if it were their own family's. That idea still shapes every decision we make.

Three quotes and Hollis & Grange Builders was the only company that actually explained the options. New boiler fitted in a day, the engineer left the cupboard cleaner than he found it.

Pipe burst at 11pm on a Sunday. They were here within 90 minutes, fixed it and the price was exactly what they quoted on the phone.
