Support & Maintenance
Your advanced security systems are critical investments designed to protect your people, property, and operations. But like any sophisticated technology, they require consistent care to perform at their peak. At WJ Sunstone Services, we go beyond initial installation to offer comprehensive Proactive Maintenance and tailored Service Level Agreements (SLAs), ensuring your security infrastructure remains fully operational, compliant, and effective 24/7, 365 days a year. We provide the peace of mind that comes from knowing your systems are monitored, expertly maintained, and always ready to respond.

We have used Sunstone at Ditton Parish Council for several years. They installed replacement CCTV cameras for us and have carried out annual maintenance since. They are very professional and the service we receive is excellent. Would highly recommend. ​Ditton Parish Council
Marc and the team at Sunstone have been nothing but helpful. They have set up and maintained our cctv system for several years now. They have always listened to what we needed and advised us accordingly. We really value the company and have recommended them to various others over the years. ​Burstow Parish Council
