The origins of the company date back to 1849, when Francis Berrington Crittall bought the Bank Street ironmongery in Braintree, Essex. However, it was not until 1884 that the company – by this time run by the founder's son Francis Henry Crittall (1860–1935) – began to manufacture metal windows. Five years later (1889), the Crittall Manufacturing Company Ltd was incorporated. At this time the firm's output in a two-year period was 20 tonnes. In 1880 the company employed 11 men, by the 1890s this figure was 34, by 1918 500.^[3]

In 1907, Crittall bought the so-called Fenestra joint patent from the German company Fenestra in Düsseldorf. In the same year, Crittall began to operate the Detroit Steel Product Co, the first steel window factory in the United States.

During the First World War, Crittall's factories were used in munitions production, but postwar the company returned to steel window manufacture. It formed a manufacturing agreement with Belgian firm Braat in 1918 and opened a works in Witham, Essex in 1919, partly to supply standard metal windows for the UK government's housing scheme.

The 1920s saw operations established in South Africa, India, Australia, New Zealand, Germany and in Washington, D.C. in the USA, followed by a company in Shanghai, China in 1931. The company also had a factory at Foots Cray, Kent, on a junction still known as "Crittall's Corner".^[4] Amid this corporate expansion, the company started a model village at Silver End in Essex in 1926.

The name most associated with the company at this time is that of W F Crittall, known as Mr Pink, who as both director and designer was responsible for the development of the steel windows and who was closely associated with the modern architectural movement that such windows are associated with.^[5]

In 1939, Crittall built its first galvanising plant at Witham, shortly before it once again became engaged in munitions production during the Second World War.

During the 1950s, Crittall began to manufacture aluminium windows and curtain walling, and in the 1960s was instrumental in the development of pressure chamber weather performance testing standards that are still used in the UK today.

The postwar period has seen Crittall undergo several major corporate changes. In 1965, it merged with Henry Hope & Sons Ltd to form Crittall Hope – a firm that was then taken over in 1968 by Slater Walker Securities. Six years later, in 1974, Crittall-Hope was acquired by Norcros Ltd, and Crittall Windows Limited Braintree and Witham was formed.

In 1990, Crittall moved to new premises in Braintree. Five years later, it was acquired by Apax Venture Capital, and then sold two years later (1997) to Marmon Corporation of Chicago. In 2002, the company was acquired by Laurel Holdings, and was then the subject of a management buy-out in 2004. In 2007, the company opened a new factory and head office in Witham.

The company had a long historical association with Braintree Town F.C. The club was originally formed in 1898 and accepted into the North Essex League as Manor Works FC, the company's works team. The club's nickname "The Iron" also comes from this source, reflecting the company's metal window frames. The club's crest reflects its origins and shows the factory of the old Crittall Garage which overlooked the club's Cressing Road ground before being demolished in 2005.

In 1921 the club changed its name to Crittall Athletic FC and soon afterwards moved to a new stadium which has been their home since. Around 1968 the club changed name once again, this time to Braintree & Crittall Athletic FC, but when links with Crittall ended in 1981 they became Braintree Town FC.
