Timothy Poppleton | Forest Gate | 20th December 2025
“I wasn't sure whether I should have this done. Tarquin was direct and honest with me. On the day, Milto showed up on time and tried his hardest to get heat to my 2 dead radiators. It didn't look like it was going to work and I was so disappointed given the expense. I spoke with Tarquin and we discussed my options. Again I considered him to be honest and trustworthy. Milto kept trying and by the time he left mid pm, my 2 dead radiators were warming up. A few hours later, they were nice and toasty. This product really is very effective at unblocking any corrosion within the system. And I can now report that my heating system is working noticeably better throughout the property. I am very impressed and pleased I had this done. I wouldn't hesitate to recommend Tarquin and Milto.”
