10 Moving lights around
Posted 06 April
Can’t fault Rob in anyway. Within 24 hrs of contacting him work has been completed very satisfactory. He moved 3 lights from downstairs and moved them to 3 bedrooms and replaced the ones he moved. Very polite and thorough in his work. We need a bit work and I have no hesitation in having him back. Extremely happy with all aspects of his workVerified reviewerJob location: SA14Response from Hartz Electrix Ltd
