When Tesco or Co-op open yet another store, companies such as this Birmingham firm are on hand to carry out any refits that are required. Probuild also does about 40 refits a year for smaller shops and offices, worth about £25,000 each. In addition, the company has a small-projects division working mainly for Sainsbury’s in conjunction with Alfred McAlpine, the property support-services group. Founder Anthony Sherlock incorporated Probuild as a limited company in 2003, and in 2004 had just one big customer. Nigel Ford joined as operations director and together they have increased the main client base to 12 companies. Sales have grown 151% a year from £327,000 in 2004 to £5.2m in 2007.
