Expression 37 specialises in the long-term support and maintenance of business-critical ExpressionEngine and Craft CMS websites. Most clients come to us with an existing site that needs a specialist to take proper ownership of it, whether that means a major version upgrade, taking over from a previous developer or agency, or ongoing retainer support. All work is handled personally by Karl. If your website matters to your business, you are in the right place.

A meaningful part of the work we do at Expression 37 involves inheriting Craft CMS sites that were built by developers or agencies who are no longer involved. The circumstances vary, but the practical challenge is always similar: a site you didn’t build, with code you didn’t write, and decisions that were never documented.
If your Craft CMS site connects to any external service, whether that’s Stripe for payments, HubSpot or Salesforce for CRM, or Mailchimp for email, you have a dependency that you probably don’t think about until it fails. Integrations break. Here’s why they fail and what to do about it.
Craft CMS has a strong but relatively specialised developer community. The difference between someone who has built seriously with Craft and someone who has touched it once or twice is meaningful. If your site runs on Craft and you need ongoing development or support, knowing what to look for matters.
Karl is the founder of Expression 37 Ltd and has been working exclusively with ExpressionEngine and Craft CMS since 2007. He works with a small number of clients on an ongoing basis, supporting business-critical websites that need a specialist who genuinely knows their system. Most clients are on long-term retainer arrangements. You deal directly with Karl throughout, with no account managers or junior developers involved.

Thornfields has relied on Expression 37 for our ExpressionEngine website for a number of years now, and the level of service has consistently been excellent. The site is central to how we promote our training programmes, so reliability matters a great deal to us. Any issues are dealt with quickly, updates are handled without disruption, and Karl takes the time to understand what we actually need rather than just applying a generic fix. We would not hesitate to recommend Expression 37 to any organisation that needs a genuine specialist looking after their site.
