Much better price — Jane T. form Deptford, South East London – SE8. ( 6th of February )Having had an estimate from another company who demanded total payment up front by bank transfer, I decide to look at other options for HIU repair. I contacted about 5 companies. Add Detail got back to me very quickly with a much better price and only wanted the cost of parts up front which I could easily pay by credit card. Jason the engineer arrived at the agreed time (he was early in fact) and did an excellent job, making sure that the system was working properly. He was very polite and made no mess. I have recommended this company to others on my development as there are always people having problems with the HIU's.
HIU Service — Erwin D. from Plaistow, East London – E13. ( 21st of January )The HIU service timing was very efficient, engineer that attended my property was accommodating to all my questions. Service value is definitely worth it.
Respectful and friendly — Michel B. from Stockwell, South West London – SW9. ( 20th of January )The service guy came out within 24 hrs of me calling them, knew to find the solution to the problem and fixed it. He was respectful and friendly, explaining along the way what he observed and gave a few tips on top of it. Thanks! Great service
