TESTIMONIALS

We found all aspects of the service very good

Attention to detail, quality workmanship, fully tested the system, cleaned up and removed all rubbish. Would have no hesitation to recommend them. All aspects from estimating, planning, coordinating, implementation, invoicing were all spot on. Brian was extremely helpful and went the extra mile to ensure everything went smoothly.

DSI came out early this morning 7.30 am to fix a problem with our entry phone key pad system. We have used this company many times for our entry phone system and found Colin to be very reliable and always gets to the bottom of the problem. Would definitely recommend DSI.
