Banaglaze – Part of the SEH BAC brand

Banaglaze Windows rebrand 2015

Established in 1982, served Chesham and south-east Buckinghamshire communities with high quality energy rated window and door installations at affordable prices.

Acquired by One Group Construction in 2015, Banaglaze was rebranded and merged with the SEHBAC brand. After 33 years of delivering outstanding home improvements and services in Chesham and the surrounding areas, the only way Banaglaze could flourish was to join forces with the South East’s most reliable and trustworthy glazing experts.
