 Trustindex verifies that the original source of the review is Google. Neil and his team are brilliant. Had a problem that Watercare  refused to recognise. Neil, through  his professionalism, persistence and willingness to go the extra mile discovered a split water main Watercare was unaware of.
It flooded my garden for three months and was ignored. Neil sorted it, all in good spirits and at a very fair price. In my book he’s a saint.

From the moment I made my enquiry about household stormwater damage and repairs, Neil's assessment - right through to the completion of the job was nothing short of an exceptional experience. Neil runs an impressive operation, supported by a fantastic and highly capable team.

 Trustindex verifies that the original source of the review is Google. I cannot recommend Neil from Mc William Drainage highly enough as a drain layer. From start to finish, his professionalism and expertise made a huge difference to the success of our project. Neil was always punctual, arriving on time every day, which kept everything on schedule. He worked within the agreed budget without any unexpected costs or delays. In fact, he managed to complete the entire drainage work ahead of the original timeline, which was a huge plus for us.
Neil’s experience really shines through in the quality of his work. He approached every aspect of the job with great attention to detail and care, ensuring that everything was done to a very high standard. Throughout the project, Neil was extremely helpful and approachable — always willing to answer questions, offer advice, and find the best solutions when challenges came up. There were no hiccups or setbacks at all, which is a testament to his planning and skill.
As a developer with many years in the industry, I’ve worked with numerous drain layers, but Neil from Mc William Drainage stands out as one of the best. His reliability, communication skills, and hands-on approach made the whole process smooth and stress-free. Neil not only did the job but did it with a level of professionalism and dedication that is rare to find.
I will definitely be using Neil from Mc William Drainage again for future projects and would highly recommend him to anyone who wants a top-quality, dependable drain layer who delivers excellent results on time and within budget.
