GSB Drainage is built almost entirely around Graham (Graham Bott), named in nearly every review for unblocking sewage pipes, bath and kitchen drains, and investigating drainage issues across new-build and older properties around Southampton. Reviewers repeatedly describe him attending the same day or within hours, even for non-emergency call-outs, and using proper diagnostic equipment such as a jetter to trace and clear blockages hidden behind covered manholes. Several customers mention his patience with elderly or vulnerable residents and his habit of only charging when work is actually needed, waiving a call-out where a blockage cleared itself on inspection. Reviewers consistently praise fair, reasonable pricing and a friendly, expert manner throughout. As a drainage service in Southampton, GSB Drainage holds a 5-star average from 60 Google reviews.

5.0 / 5 · 60 totalGraham was great. He was so friendly and helpful. Did a great job and really sorted our issue. Would highly recommend Graham without hesitation. First class service at a very reasonable rate. Will definitely recommend him to friends and family. Thanks Graham
Couldn't recommend GSB enough. Came over the same day and unblocked my sewage pipe within the hour. Very happy with the price. Top notch service
Called Graham about a blocked drain. Friendly and helpful response and he came out later that day. Arrived as expected, efficiently dealt with the issue. In the nicest possible way, hope I don't need Graham again, but I would very happily recommend him! Thanks so much Graham
Decided to contact GSB based on previous reviews and I’ve got to say I was not disappointed. Graham is super efficient friendly and explains everything very clearly plus his charges are very reasonable. Cannot recommend more highly if you need drainage issues dealt with.
Graham came out within a few hours of calling for a non emergency. His expertise was valuable in finding out an issue with our drainage when we thought was just a blockage. Would 1000% recommend. Friendly , polite and above all an expert in his field!!
Great Service. Although Graham did not carry out any work (blockage only needed slight nudge on inspection), the response and customer service were excellent throughout. I will be saving his number for any future work needed.
⭐️⭐️⭐️⭐️⭐️ Had a great experience with GSB Drainage. They provided top service at a very reasonable price, and their customer care really stood out. Friendly, professional, and efficient. Highly recommended if you need drainage work done.
