Problem with sealant in shower

The original fitter had been back twice and put new silicon in the shower but i still had water coming down the walls in the dining room when I had a shower.
Ashley took out the old plastic tray and installed a new stone tray and even covered up the sides of the shower unit plinth that had been left by the previous installer. I was happy to leave him working in the house whilst I went to work.
When I noticed a small leak 10 months after this installation, Ashley came round within the hour of me contacting him. He checked whether the leak was in the waste pipe and having established it wasn’t he siliconed round the shower as a precaution. He also helped me identify what the problem with my boiler losing pressure was.
As a single lady with limited knowledge of plumbing, I trust Ashley to undertake work reliably, on time, on budget and to a high standard.
