Seijsener’s Full Service

Seijsener has been serving the caravan and marina industry for almost 60 years. During that time Seijsener has nurtured and supported infrastructure projects for caravan sites, ports, marinas, campsites, holiday and residential parks from start to finish.

Seijsener aims to realise a design that will last for many years to come without a problem. Even under extreme circumstances such as wind, salt water and waves. That’s why we design, manufacture and install most products ourselves, choosing materials and design constructions which result in the highest quality. And we use well-trained, experienced professionals to manufacture in our own factory, using ISO 9001-certified working methods.

Seijsener prides itself on providing additional services, to make sure that any individual requirement can be met.

Design & Consultation

Seijsener-Techniek-bungalow technique

Every successful (infrastructure) project starts with sound advice. And Seijsener brings that right away – whether it’s about the design, construction or maintenance and management of your installations, or advice on existing installations about their sustainability or where cost savings might be made. Our broad expertise guarantees a well-thought-out technical and functional design, resulting in tailor-made advice and a quote that fits your budget.

Installation service

Your project is in good hands at Seijsener, whether large or small. We use experienced and certified all-rounders instead of different mechanics for each installation, for example the construction of electricity, gas, water, lighting or access control. You have one point of contact, a permanent field service consultant, permanent project manager and a permanent all-round assembly team, keeping quality control along the way and using the best products manufactured and supplied by Seijsener.

Service & maintenance

Seijsener can take you from start to finish. From good advice, a well thought-out plan for cost-effective infrastructure, the construction of the right installations or connecting to existing networks. You can leave everything to us. We are also happy to take care of all the care in the field of service and maintenance. With preventive maintenance of your installation, you minimize the risk of failure. This will save you more time and more money.
