About Clarks
50 Years, Three
Generations, One Name.
Clarks Construction Ltd is a third-generation, family-owned main contractor based in St Albans - widely regarded as one of the best construction companies in Hertfordshire. We deliver education, commercial and industrial projects valued between £1 million and £10 million across Hertfordshire, Bedfordshire, Buckinghamshire and London.
Founded in 1976 as Clark & Son, we've grown from a local building company into a principal contractor trusted with some of the region's most demanding projects - from science laboratory refurbishments at St Albans High School for Girls, to residential development schemes for developers across both luxury and non-luxury markets, and office conversions in Belgravia.
The name on the vans has changed once in fifty years. The family behind it hasn't.
Our Values
Family Heritage
Three generations of construction excellence since 1976. The family behind the name hasn't changed in fifty years.
Client Partnership
A collaborative approach with every project team and client. We take accountability and anticipate problems before they arise.
Proven Expertise
From London Zoo's historic Reptile House to Grade II listed Georgian townhouses in Belgravia - no project is beyond us.
Communication
We overcommunicate, by design. We share early, we don't hide bad news, and we say things clearly and honestly - directly but respectfully, always with a solution in mind, never blame.
