Based in Teesdale but willing to travel anywhere in the UK, Alan Heavisides has a large, fully equipped workshop that makes and renovates traditional box sash windows that are double-glazed to meet modern building regulations.

SPECIALISED JOINERY
Unit 4, Clarkes Industrial Estate, Sutton Coldfield, West Midlands B73 5TS, www.specialisedjoinery.com
This family firm is always incredibly busy, so you may need to wait between eight and 12 weeks for your windows, but its work is highly recommended. Choose from good-quality softwoods, or hardwoods such as mahogany and oak, all of which are from renewable sources. Features include single or double glazing, locking catchments, draughtproofing and the option of sash stops, which restrict opening for child safety. Windows are finished with a wood preserver and primer, ready to be painted on-site.
