10 Blocked Drains
Posted 18 April
Difficult Drain blockage solved .
Quick response to a blocked drain and problem quickly found to be a very large fat berg in a difficult to access part of the drain . Jet washing flushed out the obstruction from the property after two hours of uncomplaining effort . His hourly rate is quite reasonable plus gave a further reduction due to extended time . With another firm I contacted , the bill would have been enormous . Also provided a quote for improving access to the drain . Very pleased and would be confident to use again.Verified reviewerJob location: SO1510 Blocked Drains

Clogged toilet waste cleared very quickly
I reached out to Graham directly via the Checkatrade App based on his fantastic reviews and wasn’t disappointed. Graham responded within the hour and came round the next day. He diagnosed the issue quickly, explained what he’d do to fix it and worked really efficiently to get things back to normal. If you’re in Southampton - or nearby - just message him. I would 100% recommend his very professional service.Verified reviewerJob location: SO14RVicky CResponse from GSB Drainage

Outstanding
I urgently needed someone to check a property with a serious blockage issue. Before Graham, another so‑called “specialist” spent nearly two hours trying—and failing—to fix the problem, then charged a staggering amount of money for doing nothing. I called Graham, and luckily he was already in the area. It was after 5pm, but he still agreed to stop by once he finished his current job. He arrived, used a camera to inspect the drain, and cleared the blockage within 15 minutes! He was honest, professional, and incredibly helpful. Truly top‑quality service, and I’m definitely keeping his number.Verified reviewerJob location: SO15Response from GSB Drainage

Fantastic service
What a fabulous service by Graham, who was professional, prompt, reliable and one of a kind person, altogether a super guy. Came immediately to a ongoing blocking toilet which has been a problem for quite a while at my daughters house in Southamption. Going above and beyond to resolve the matter, it's so reassuring to know as I live abroad that there is Graham there to help with any other drainage problems. Price was more than reasonable too. Would highly recommend. Many thanks GrahamVerified reviewerJob location: SO32Response from GSB Drainage
