Cost is important to us as well. We prefer to see the job first, as it avoids unpleasant surprises for us as well as the customer. What we don't want to have to do is to tell customers their wiring is dangerous and needs repair before we connect a light etc. but it saves money if we can see your home/ business beforehand. It won't cost you anything for us to look at the job and let you know up front how much it will cost and often we can reassure people who may have doubts about the safety of their home or business. A full check of your system will incur a cost but an initial estimate will not. So get it done because IT'S FREE!!
