We have an in-house Consultant that can advise, and prepare costings and design drawings for all of your needs, and organise the installation during construction with your Builder. 

Likewise, our trained Technicians can visit your home to carry out routine servicing ond rectification of your current systems. We can retrofit any or all of our products and provide monitoring services etc, along with competative pricing. As the analogue Television signals are phased out, older homes will need a Digital TV antenna to replace the older analogue antennas. We can provide these as well as data cabling for Smart TV’s etc. Surround Sound cabling, HDMI cabling and all other types required for the modern home.
