10 Water Pumps Installation
Posted 3 days ago
very professional
Sav was very professional, he explained everything to me about what could happen since the pump is very old, but with his skill and experience, the job was very well done. Now I hope it works for a long time like it does now. If I need another plumbing job, I’m sure I would use the same company. Thanks Daniel and Sav for your professionalism.Verified reviewerJob location: SW18RFernando R10 Gas Safety Checks - CP12

Highly recommended
Sav came to repair a gas leak and do a safety check. I couldn't be happier with the job. He was upfront and honest and the work was completed quickly and for a good price. I'll definitely be using this company again.Verified reviewerJob location: SE1710 Power Flushing
