What customers say

Based on genuine customer reviews

Sutton businesses and households have relied on Monster Drainage Ltd for drain unblocking and CCTV survey work, and the feedback gathered from fifteen accounts consistently points to swift call-outs and a careful approach to diagnosis. Several customers describe the team arriving within two hours of a call and clearing a blockage successfully on the first visit. Reviewers frequently point to punctuality, with engineers turning up when they say they will and completing work in the time promised, whether the job is a full drainage clearance, a CCTV survey or the diagnosis of a recurring problem.

Something that features in review after review is the advice given on site, especially where earlier contractors had shown little interest in the underlying cause; the findings here were said to be more accurate, resulting in fewer repairs than first feared. Kevin is named for explaining issues clearly and helpfully, and the wider staff are described as friendly, conscientious and professional. Tidiness is noted after every visit, with everything left clean, and pricing is called fair for the work carried out. Customers also value the follow-up contact and being kept informed when problems arise during a job.

We booked a CCTV to diagnose a problem which had to include an unblocking as well. It take a longer than anticipated but we were happy with the work and found the service to be thorough and prompt. The diagnosis compared to a previous report we were given by another company was that our pipes were in far better condition than we'd been led to believe. This meant we needed fewer repairs and we went ahead and booked them to carry out the works.

Monster Drainage provided an excellent service. Contacted via email and they were very quick to reply and organise a visit. The service from Kevin was great, very helpful and explained the issues. Full drainage clearance and CCTV survey. Charged by the hour and cost is fair and reasonable for the work. Highly recommended!

Excellent service from Monster Drainage. The team were friendly, professional, and very helpful from start to finish. They arrived when they said they would, explained everything clearly, and carried out the work efficiently. Their pricing was very reasonable, especially considering the quality of service provided. It’s refreshing to deal with a company that is reliable, honest, and takes pride in its work. I wouldn’t hesitate to recommend Monster Drainage to anyone needing drainage services.
