How We Work

Initial Contact & Site Survey
We provide a fast and friendly response to all enquiries from our customers. A member of our team will contact you to discuss your requirements in more detail and to arrange a site survey of your premises - this allows us to provide expert advice on the security system that meets your specific needs.
Proposal & Estimate for Work
When we have all the required information from the site survey, we can then provide you with a detailed written proposal and estimate, before agreeing to undertake the work.
Ongoing Maintenance
We provide a 12 month warranty for all our installations, after which time we will offer you an ongoing maintenance contract to ensure your system is kept in good working order.
