7.33 Workmanship not up to standard

Hired LJS, they came out and stated I needed a chemical flushing, however I am still experiencing issues after 2 attempts, the trade stated it may be an issue with the boiler. Another company came out to look at the boiler but said there was nothing wrong with the boiler. LJS is convinced it is due to the boiler having a fault. However we have received confirmation it is not to do with the boiler. Dissatisfied with the amount paid as the issue was not resolved and I now need to pay again to get it fixed properly I have had to buy an electric heater to keep us warm which is costing more money.Verified reviewerJob location: SG18Response from LJS Plumbing and Heating Services

I was very impressed from the quote visit to the work being carried out. The team ensured that our carpets were protected from any work debris. They attended on time on date. The team worked late into one evening so that we wouldn’t be without heating, even though we said that they could leave the heating till the following day. When we noticed a very slow leak from one the new radiators, Luke made sure that on a day we were back from a mini break, the radiator was fixed. I would highly recommend this company.Verified reviewerJob location: MK4510 Bathroom looks great!

Found dripping coming from the pipes in the roof. Originally thought it was the ball valve in the water tank but turned out to be a different issue. Luke was very prompt, communicative and helpful. He offered a free consultation as it wasn’t the original issue we thought it was. Really appreciate the effort he went to to help us and will be using him going forward for any plumbing issues.Verified reviewerJob location: SG5
