Frequently asked questions

What can I do to prevent clogged drains?

To prevent clogged drains, avoid pouring grease, oil, or coffee grounds down the sink. Use drain strainers to catch hair and debris, and periodically flush drains with hot water and vinegar to remove buildup.

If you find yourself with clogged drains and pipes, call Hall and Randall Plumbers and one of our expert drainage engineers will get your drains washing away in no time.

How do I know if my drainage is blocked?

It can be difficult to spot drainage issues before they develop into blockages. However, some common signs that you can look out for are bubbling or gurgling drains, water backup, or foul odours coming from your drains. It is best to contact one of our specialists on 0208 953 2094 at the earliest point of these symptoms.

Why is my bath or shower draining slowly?

A slow-draining bath or shower is often a result of a partial blockage in the drain. This blockage can be caused by a buildup of hair, soap scum, or other debris over time. Usually this can be a simple fix by one of our engineers, but if the problems persists, it can be an indicator of a bigger issue.

In this case, be sure to call one of our drainage specialists on 0208 953 2094 and they will be able to carry out in-depth investigations using specialist equipment to help you identify and resolve the issue.

What causes foul odours from drains?

Foul odors can result from accumulated debris, mold, or bacteria in the pipes. Cleaning drains regularly and using natural deodorizers like baking soda and vinegar can help. If bad smells arise and continue, our specialists can help do a thorough cleaning and help clear the root cause.
