CW Pipewise is a company based in Surrey that specializes in water pipe replacement and installation services. Our services range from water pipe and leak repairs to improving water flow and pressure, as well as stop cock replacement, moling and excavating, cable moling, domestic and commercial groundworks, utility surveying and tracing, multi-utility installations, reinstatement, and civil projects.
As an expert in moling, a trenchless method for installing pipes or ducts from 20mm up to 75mm, CW Pipewise offers a less destructive alternative to trenching. We are registered as Water Safe and have WIAPS and Thames Water TAPS 5 Approval.
Our impact moling method is simple: we dig entry and exit holes up to 10 meters apart at the required depth, insert the mole, and use a sight and scope to accurately line up the mole before sending it from one hole to the other. Once the mole arrives in the exit hole, we attach the pipe to the hose that powered the mole with air and pull it back through.
All of our experts are EUSR registered and hold up-to-date National Water Hygiene cards, ensuring excellence in every job. We also hold the highest standard in CHAS accreditation, making us a reliable choice for your water pipe replacement and installation needs.
EXCELLENT Based on 38 reviews Posted on eoin maherTrustindex verifies that the original source of the review is Google. I contacted Charly to help identify and repair a leak on my water main. He came out the next day to scope the work and provided a very competitive quote. A week later he was here with Danny and did a brilliant job in installing a new pipe. The drive and patio were dug up and put back within the day, looking now you'd never even know they were here. If you need some work done Charly and his team won't let you down.Posted on Bob DownsTrustindex verifies that the original source of the review is Google. Just had our mains water feed replaced from the street to the house by CW Pipewise and can highly recommend this team of professionals. Fantastic communications, competitive quote and the work carried out promptly and to a high standard.Posted on Mike RussellTrustindex verifies that the original source of the review is Google. Great job! Charly agreed a date, team turned up on time, quickly dug 3 holes and used a mole to pull in a new pipe. Charly organised Affinity Water to make the connection and he made the new connection in the house and isolated the old connection. We now have a super flow rate. I don’t hesitate to recommend Charly and his team.Posted on Duncan CorcoranTrustindex verifies that the original source of the review is Google. I used CW Pipewise to install a new water main to my property. Charlie and his team booked me in and carried out the installation to an extremely high standard, the driveway was lifted and put back down the very same day. I could not recommend this company enough, thanks for everything guys!!Posted on neil wheelerTrustindex verifies that the original source of the review is Google.

Charly and his colleague were not only prompt and professional - they were very courteous and helpful too. Charly was knowledgeable and helpful and very quick to provide a competitive and compelling quote for works. On the day of works he was polite and mindful of not only us, but our neighbours too. He's very solutions focused and helpful which I found refreshing. Would happily recommend him to friends and family.Posted on Nasser JanjuaTrustindex verifies that the original source of the review is Google. From the estimate to the completion of the job, it was a total pleasure to have dealt with Charly and Danny. Thoroughly professional and exceptionally good at what they do, I had a main pipe replaced in a domestic property. I would highly recommend these guys, thanks again lads.Posted on Rob GrayTrustindex verifies that the original source of the review is Google. Outstanding service from Charly and team. Fixed a leak I’ve been having issues with for over 6 months. CW Pipewise were incredibly efficient, friendly and knowledgable. Fixed my leak, reinstated everything and spent a long time cleaning up even though I said they didn’t need to. Would recommend to anyone!Posted on Anders ReevesTrustindex verifies that the original source of the review is Google. Highly recommended. Nice chaps and speedy work. Relocated and upgraded our water main in a couple of hours. Amazing tech that meant minimum disruption to our drive and garage. Couldn’t be more pleased with their service.Posted on MarkKhara RogersTrustindex verifies that the original source of the review is Google. After a botch job done by our insurance company, I reached out to Charly after being recommended by Thames Water. He has been brilliant from start to finish. His team (specifically Sam) were polite, professional and took the time to help me understand underground pipe work that needed to be completed. We had to take up part of the driveway and flower beds, to lay rainwater piping and fix 3 gullies. The team left the site tidy (which is hard to do considering a mini digger was needed!) and I would definitely trust Charly and the team for future work! They respected the site, took the time to show me as pipes were laid and completed the work super quickly! We look forward to working with them again.. hopefully next time for something less urgent!
