    Dean turned up when he’d said he would. Pressure jetted soakaway and removed large amount of chalk and other debris. Very pleasant. Nice job

  • Septic Tank compliance issue


    From the very first phone call I knew I was dealing with someone who was passionate about what they did - Ashley agreed to come to our property to evaluate our septic tank for a possible sale having had a survey and queries regarding compliance having been raised. We felt they were not correct but needed to prove this. Ashley came to our property FOC to evaluate and was prompt , polite and professional - quite rare these days & totally reassured us that £10,000/£15,000 works would not be required. Cannot recommend this company more highly and would 100% use if any drainage works required.

    The team showed up as promised, cleared the drain very quickly. Only issue was the quote didn’t include VAT and didn’t specify that it didn’t.

    Thorough examination of all the pipes under 2 manhole covers, flushed them out and used a camera to ensure everything clear. Installed a valve where everything can go out but nothing comes in. Filled the hole by drain pipe and fitted an extra piece to the pipe. Elliot was extremely efficient and explained everything he was doing.

    Our whole drainage system is very old and needed extensive work. Flow Drainage did the whole job in two long days, starting on Sunday morning early. Everything is now working well. The inspired confidence throughout.

  • CCTV Drainage Survey

    10Verified Review

    The two guys that attended my property were very polite and extremely helpful. When they arrived they found that there was a blockage in the public sewer. They lifted several manholes in the road to see if they could clear it so that they could do my survey. Unfortunately they were not able to, not for lack of trying though. So although they weren't able to do the job, they went above and beyond to try and help. The receptionist at Flow Drainage was extremely helpful in trying to re-book as quickly as possible. All in all, a great company and very helpful.
