Helen Nguyen • London, UK

"Booked ASAP Drainage for a homebuyer CCTV drain survey on a Victorian property we were buying in Windsor. The engineer arrived exactly on time, talked us through the camera footage live as he went, and flagged a displaced joint and root ingress near the rear manhole that the seller hadn't disclosed. The fixed-fee £189+VAT homebuyer tier included a same-day WinCan report sent straight to our solicitor, plus the full video file. We used the report to renegotiate £4,000 off the asking price for the repair work. Solicitor-ready format, WRc-accredited engineer, clear pricing, no upsell at any point. The survey paid for itself many times over and saved us from buying a money pit. Would absolutely recommend ASAP to anyone buying a property in Berkshire or West London, get the CCTV survey done before you exchange."

"Saturday night, 9pm, downstairs toilet overflowing and the manhole outside filling up. Rang three places. Two went to voicemail and one wanted £180 just to leave the depot. Phoned ASAP and a real human picked up first ring, gave me a flat call out price on the phone, engineer at the house in Cobham inside 45 minutes. He spotted it was a mainline issue rather than anything inside, ran the jetter from the back manhole, and had the whole house flowing again within the hour. Wet wipes and grease apparently. He stayed until I'd flushed everything in the house twice over. Invoice matched the phone quote to the penny, no upsell, no ""actually you'll need this too"". Booked them back the Wednesday after for the £225+VAT insurance grade CCTV survey so we'd have a WinCan report on file in case anything turned up. Got the video and annotated PDF same day. The 28 day workmanship guarantee meant if anything came back we weren't paying twice. It's a proper family run drain company. Matt's actual engineers, not subbies driving up from another county. Already passed the 0800 number to my next door neighbour and the family across the road in Oxshott. Honestly the best drain company we've used in Surrey."

"I had an emergency over the bank holiday weekend where my underground drain was overflowing. I contacted around 10 local drainage companies, sent photos, and explained the issue in detail to all of them. Matt from ASAP Drainage stood out straight away. He reviewed the video I sent, clearly explained what needed to be done, and was the only one who could come out the same day. On top of that, he was by far the cheapest quote I received. The service was excellent – very professional throughout, fixed the problem efficiently, cleaned everything up properly afterwards, and even disinfected the whole area so it was left fresh and hygienic. Really impressed with the service. Highly recommend Matt and ASAP Drainage if you need reliable and honest work done."

"Where do I begin. I have never had a more positive experience with a tradesperson in my life. I was instantly assured that he would be able to tackle an issue that his predecessor had a horrific attitude to. The problem was solved efficiently and speedy and Matt was amazing. I have so much gratitude for my experience today! Thank you so so much!"

"Excellent service from ASAP Drainage. Prompt communication & service & super professional and lovely to deal with. We had a blocked drain under our house, Matt & James swiftly unblocked it and had everything flowing beautifully in no time. I highly reccommend them if you have any drainage issues. I will definitely use them again in the future if need be."
