Feedback for Mark

"I look after a portfolio of about 40 properties, Mark services all those with gas heating systems. He is good value, efficient, and good at communicating by email."
Nick Nixey, Vitalcrown, Watlington, Oxfordshire

"Mark has worked on Marine Engineering and gas work as well as servicing my home boiler for several years for several reasons; he is a likeable, honest, hard worker who does what he says at a fair price. Mark doesn't tap the pipes, whistle a tune then submit the bill. He does what needs to be done and he does it well. I have no hesitation in recommending him to anyone."
Rob Whitty, Private Owner, Wolvercote, Oxfordshire

"Mark really helped us out when we needed some emergency work for our gas supply and I would highly recommend him".
Chris Andrews, Private Owner, Cholsey, Wallingford, Oxfordshire

"Happy to recommend Mark for boiler service and repair. He came out promptly to do an emergency fix, persevered when it wasn't straightforward and came back and repaired the boiler when several other people said it needed replacing. He is reliable and his charges reasonable and it's a great relief to find someone who does a proper job and doesn't rip you off!"
Penny Smith, Private Owner, Woodcote, Reading, Berkshire

"Mark has worked at our house for a number if years carrying out a variety of task on our boiler and heating system. Mark works with professionalism, integrity, and a warm manner. Notably Mark is keen to do the right thing both technically and economically, rather than opting to replace all internal parts at great expense without really finding the original problem. Mark is one of the few tradesman I have complete confidence in".
Matthew Doughty, Private Owner, Cholsey, Wallingford, Oxfordshire

"I would strongly recommend Mark Brock as a very helpful, professional service engineer. He works very efficiently and safely.He helped me just before Christmas when I had a gas leak".
Chantal, Private Owner, Crowmarsh Gifford, Wallingford, Oxfordshire

"Mark has done a couple of jobs for us. He repaired some old - but good - taps that I had been told would have to be replaced, and, having installed a new radiator, moved the original to another room in order to match another (old) radiator. Our house is somewhat quirky in plumbing terms, and on both occasions, Mark did the job efficiently and with meticulous attention to detail. He is punctual, communicative and clean and tidy at work. Highly recommended.".
Penny, Private Owner, Berrick Salome, Wallingford, Oxfordshire
