"Great experience. I can’t fault GWG. When my outside water pipes failed and my insurance didn’t cover the repair, I was so glad to find this company. They came and quoted almost immediately and the work was booked in promptly. All aspects of the work were carried out to a high standard, with little disruption."

Customer voice from the public record
"Had a great experience with GWG. Gareth made time on a weekend to consult and quote, and fitted us in shortly thereafter. Works to replace/upgrade our shared and individual supply pipes were done quickly, to a really high standard, and with no residual disturbance/mess. Great communication with Gareth throughout."
"I would highly recommend Gareth and his team to anyone. Easy to communicate with, replied quickly and concisely and explained everything that I needed to know. At a time where I was incredibly stressed with leaks and Water suppliers, Gareth was the calm! Very polite, got the work done quickly and tidied everything before they left explaining everything they had done and leaving me with the paperwork that I needed."
"We had Gareth from GWG come and do a few different jobs for us when we moved into our new house that needed an extension and updating. The whole service was very professional. Gareth showed he had lots of experience in the trade when problem solving and completed all our works to a good standard."
"I am delighted with the high quality and the value for money of the work that GWG Watermains have undertaken for me. They used 'moling' to replace a leaking mains supply pipe with a larger diameter pipe, from external stop cock in a driveway to kitchen water meter. This avoided damage to the granite setts of my driveway and improved flow. The high quality of their reinstatement means it is extremely difficult to see where the work was carried out."

Water supply pipes replacement on private side in compliance with Affinity Water regulation and additional new supply to garage: Gareth of GWG Watermains was friendly and polite throughout and kept me informed during the whole project. His quote was the most competitive and he confirmed that he would be carrying out the work in person. He arrived along with his colleague punctually on the appointed date/time and they worked hard throughout the day. They kept me fully informed and showed me each stage of the job. Gareth provided a number of photos of the job which I sent to Affinity and he waited whilst I confirmed with them that the job was complaint. They then cleared up, made good really nicely and supplied a certificate of compliance. In summary I am very pleased that I picked Gareth at GWG to undertake this work. I would definitely recommend him and I will call on him if I require this sort of work in the future..
Tidy prompt and a fair price . Laid a new mains water pipe 800 m In a few days .
My house had an underground water leakage this Summer, luckily Gareth came to help. As I wasn't sure what to do, the on-site repair or the pipe replacement, he provided me with two separate quotes, both were reasonable. He was knowledgeable and friendly and answered my questions by phone or email promptly. I finally chose the plan of replacing the pipe in between the external stop and the internal main stops. On the day of proceeding, Gareth and his team members discovered a hidden route to reach the internal main. They opened up the under staircase to let the pipe run through to avoid the copper water pipe running visibility around the staircase and the showroom. In the end, no new water pipe was visible at all! I recommend Gareth and GWG watermain without hesitation.
