Expression 37 specialises in the long-term support and maintenance of ExpressionEngine and Craft CMS websites that businesses depend on every day. Most clients come to us when their site has become difficult to trust, whether the developer relationship has ended, a major upgrade has been delayed for years, or the site has simply grown beyond what the original build can handle. All work is handled personally by Karl. If your website matters to your business, you are in the right place.

Expression 37 works with a small number of clients at any one time. These are some of them.
Every client came with a real problem and a website they could not afford to have fail. Here are a selection of the engagements and what was involved in each.
Craft CMS
Custom PHP
ExpressionEngine
Practical writing on ExpressionEngine, Craft CMS, and the kind of problems that build quietly until they can no longer be ignored. Written for business owners, not developers.
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. In eighteen years he has supported more than 80 clients across the UK, from long-term retainer arrangements to emergency rescues when something has gone wrong at the worst possible moment.
