As a carpet fitter and retailer myself I know what a bunch of arrogant idiots the majority of carpet fitters are. Although cables should not be fitted under carpets it is a practice that is carried out. The safest way to do this with any cable that caries any charge is in between two grippers. Anybody can find an easier or quicker way of doing it, this is not modern practice but corner cuttting. Damage to cable is not possible to see from the outside they are like wheel bearings all the damage is internal caused by the internal friction of the wire rubbing together it is onlyposible to stop this compression by making a solid channel with the gripper.
I am all for anybody becoming a competent fitter and offering the service described but again from 20 years of experience the money is in the cleaning. The people that have the damage, badly fitted carpets, fAg burns, badly fitted doorbars etc etc, always ternd to be the lower end jobs where the price for your time become unrealistic. People at the quality end normally have good quality well fitted products. I will go for long periodswithouot even touching my fitting tools. Carpet fitters at present are 2 a penny the flooring market has gone through a bad few years so I would not reccomend anybody go into fitting to compete with the many that are scratching for work. We get several c.v. s sent to us all the time. It is the same as a lot of things once you have invested in the training and the tools you would have probably been better investing that into taking your core business forward.
