How to choose between them
A whole-home job in Darlington typically runs £2,500 to £7,500 (local cost factor 0.83×), so the spread between three quotes on the same brief is worth chasing. Railway-era Victorian and Edwardian streets around Northgate, terraces off Yarm Road, plus interwar semis in West Auckland Road and Blackwell.
Heritage note: Around 15 conservation areas including Blackwell and Cockerton.
Whichever company you approach: get three written, itemised quotes, confirm FENSA or CERTASS registration on the scheme's own register, check the guarantee is insurance-backed, and ask for two recent local installs you can look at. Our guide to comparing double glazing quotes walks through it.
