 Trustindex verifies that the original source of the review is Google. Honestly can't fault Billy, turned up quickly to unblock a downpipe which was causing damp inside my house and then followed up with replacing the whole lot.  Communications were excellent and I was particularly impressed by the fact he messaged me to let me know he was on his way. Well impressed!

 Trustindex verifies that the original source of the review is Google. Billy came out to a blocked drain at my house within the hour. Billy cleared the blockage, explained the issue and the cause, showing me images through the drain camera and what we need to do next to resolve long term. Billy is open and honest and explains thoroughly...he also resolves. 100% would always use NW Drainage. Thanks again

 Trustindex verifies that the original source of the review is Google. Great service. Our outside drain had been broken into and blocked by tree roots and needed replacing. In just a few hours the roots were removed, the drains were replaced and the whole area was left much tidier and easier to maintain. Billy explained everything before, during and after so that I knew what was being done and there were no surprises. I would highly recommend Northwest Drainage 24/7. Pics of before and after.

 Trustindex verifies that the original source of the review is Google. Billy was super informative, efficient and resolved our drainage issues promptly. He really did save the day and discovered a problem we didn’t realise the severity / would not have been able to locate ourselves. Would recommend completely. Fair and reasonable pricing for excellent service.

Frequently asked questions about drain unblocking.

What causes blocked drains?

The most common causes are grease and food waste, wet wipes and sanitary items, hair and soap build-up, silt, and in some cases root ingress or damaged pipework.

Do you offer emergency drain unblocking?

Yes—Northwest Drainage 24/7 provides emergency drain unblocking 24/7 across the North West.

Will jetting damage my drains?

High-pressure jetting is safe when used correctly by trained engineers. If we suspect fragile or damaged pipework, we’ll advise on the best approach and can complete a CCTV survey if needed.

The drain keeps blocking—why?

Repeat blockages can indicate underlying issues such as pipe damage, incorrect falls, root ingress, or persistent build-up. A CCTV drain survey can pinpoint the root cause.

Can I unblock a drain myself?

Minor slow drainage can sometimes be improved with safe cleaning methods, but if there’s overflow, repeated blockage, or strong odours, it’s best to get professional help to avoid worsening the issue.
