The history of T & K Home Improvements

TKHI original van


Kevin Johnson and his then business associate, Tony Foster, commenced working from Tony’s garage and spare first floor bedroom. They made double glazed units to go into aluminium frames that they sold and installed. Their supplier of aluminium windows and doors went bust a few months later so they bought their stock and machinery, employed a fabricator and commenced manufacturing their own windows.

Late 1979


They moved from the garage and first floor bedroom into a small industrial unit in Alexandra Road, Wellingborough, before relocating again to Burton Latimer before the end of the year.

July 1979

Windows & Doors

They purchased their first freehold factory in Allen Road, Finedon where they began to fabricate the innovative ‘new’ product, internally beaded PVC-u windows and doors.
