10 Gas Central Heating Servicing / Repair

Gas capping and fixed unexpected issue
I cannot recommend Paul enough. He was the man for the job. He went above and beyond to ensure the work was done efficiently and properly. And even solved an unexpected (but potentially serious) problem there and then. So effectively solved two problems including gas capping done promptly. If I were to rate his work, outstanding is not enough of a compliment. I help my uncle take care of his property, and my uncle is not fully able, so honest, competent and willing workers like Paul are honestly lifesavers! Paul, I will contact you for the cooker issue later 👍 Top class and professional 👍Verified reviewerJob location: CV6RSamina HResponse from Castle Gas
