How to choose between them
A whole-home job in Glasgow typically runs £2,600 to £7,900 (local cost factor 0.88×), so the spread between three quotes on the same brief is worth chasing. Sandstone tenement flats define the West End and Southside (three or four storeys, high ceilings), interwar semis in Cardonald and Bearsden, and postwar tower blocks across Easterhouse and Drumchapel.
Heritage note: 23 conservation areas including Glasgow West and Pollokshields - many tenement blocks are B-listed, restricting frame changes.
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.
