    Great Gas Engineer

    Posted 11 August

    Jack has changed both my Mums and my boiler in the last few months, serviced my Megaflow and changed the radiator valves in my house. He was very professional, accommodating and clean and tidy. We received all the certification and guarantees. I would definitely recommend Jack.

    Highly recommended

    Posted 28 July

    After not having hot water for three weeks I was desperate to find a heating engineer to look at my boiler. I wanted someone reliable and honest and a friend recommended Jack as he was known to her family. He came and checked the system and very quickly got the water working. He was polite and efficient and told me the options I had to have the heating working at a later date. I feel confident that the rest of the work will be done well and be well thought out to give me the most cost effective system. I’d be happy to recommend J Sandford to anyone in need of a reliable heating engineer.

    Boiler Installation

    Posted 09 July

    We highly recommend Jack. He replaced our dangerous old boiler and did an excellent job from start to finish. He was friendly, reliable, and professional throughout the process. He explained everything clearly, arrived when he said he would and carried out the installation to a very high standard. It's reassuring to find a tradesperson so trustworthy. I wouldn't hesitate to recommend him to anyone needing boiler repairs or replacement work. Excellent service!

    Boiler installation

    Posted 08 July

    Jack removed our old boiler and replaced it with a brand new one all within half a day. The new boiler looks great and Jack communicated exactly what work was carried out and even spent time after the work was completed to answer any questions we had. 10/10 would recommend to anyone.

    Servicing of the boiler

    Posted 02 July

    Jack was fantastic from start to finish. He was able to come out the very same day, which was hugely appreciated. He was friendly, chatty and professional throughout, and even took the time to make a fuss of our dog, which was a lovely touch! The boiler service was carried out efficiently and the whole experience was hassle-free.

    Domestic Gas Safety Record

    Posted 01 July

    We’re in the process of buying a house and wanted to check the boiler and gas appliances. Jack was so helpful and very communicative, which we really appreciated as he needed to arrange the visit with the sellers. He was able to book in and visit quickly, and we received the record the same day. Highly Recommend. Thank you Jack!
