Jason and Paul did a great job on replacing mums mains water pipe. They arrived at 8 and were finished by 12. Everything was left so clean and tidy, hole in the drive patched and flower bed refilled and re-planted, Mum also wanted me to say how cheery they were, putting mum at ease. Would highly recommend T&L Moling contractors. Thank you Jason and Paul

A massive thanks to Paul and Jason at T&L who fitted a new mains supply to our house at short notice to replace an old, leaking, lead supply. Paul communicated clearly, provided a detailed and professional quote in short order, turned up on time and him and Jason worked hard to get the work done as quickly as possible. Great experience, would definitely recommend.

No hesitation in recommending T&L, both Paul and Jason have been extremely helpful, great communication and honest advice. The job was done quickly and professionally, certified and with the photo evidence needed to share with the water board. T&L gave the confidence needed to get the job done!

Paul was great. Fitted me in last minute. Really professional and personable. Very good price and very efficient. All done in 5 hours. Nothing was too much hassle even when I changed my mind for the stop cock location after the pipe was already run. They also ran a temporary connection back to the current mains water location under the stairs as this will be relocated by my plumber at a later date to the new stop cock location. They even left my front garden tidier than when they started :) Would recommend highly. I received my certificate of install the same day and they can connect directly to the water meter as they are WIAPS approved so no need to wait for thames water final connections.

Highly experienced and friendly company, a pleasure to deal with. We had an external lead water pipe that needed replacing, found this company via Google search and they got back to our web form submission super quickly to agree on a quote and timing. Arrived on time, completed the repairs, put everything back in place (patio tiles etc) meticulously once the works were completed and provided the works certificate promptly. Thanks again to the team at T&L.

Paul and his team did a fantastic job moling our water supply. He was incredibly punctual, came to inspect the property the day after I requested a quote, and completed the work to a very high standard. The job was carried out efficiently and with great care, leaving everything clean and tidy afterwards. I wouldn't hesitate to recommend Paul to anyone looking for reliable, professional, and high-quality work.
