CSD set to seal growth with recruitment drive

A North East engineering company is expanding its workforce after achieving double-digit growth, driven by rising demand from the power, water and renewables sectors.

CSD Sealing Systems is recruiting for multiple roles across the business as it continues to secure major infrastructure projects and meet growing demand for its specialist fire protection sealing solutions.

Founded in 1993, the company, which currently employs more than 50 people across the North East and the UK, designs and supplies cable transit, pipe penetration and sealing systems that protect critical infrastructure from fire, water, gas and smoke. 

Recent growth has been supported by projects with organisations including Siemens Energy and Hitachi Energy.

CSD’s solutions are being used across data centres, substations, nuclear sites and marine environments, where long-term safety and resilience are essential.

Bosses say the recruitment drive will support both new and existing projects while creating long-term career opportunities in specialist engineering, installation and project delivery.

Managing director David Ripley said: “We have seen a strong start to 2026, with double digit growth and lots of new opportunities for our team. 

“The scale and complexity of the projects we are supporting show the growing importance of specialist sealing systems in protecting and growing the UK’s critical infrastructure.

“From substations and data centres to nuclear and marine environments, our team is delivering solutions where performance, compliance and long-term reliability are essential. 

“That demand is creating further opportunity for us to continue to grow our team and bring more opportunities to the North East and across the UK.”
