How to fix a draught behind a toilet

A draught behind a toilet can be very annoying. The good news is that they are avoidable and can be fixed relatively easily. Some people may be confused as to how a draught gets in as their pipework may be tiled or boxed in, yet they still feel a draught in their bathroom or toilet.

Where is the draught coming from?

The root of the problem often lies where the pipework servicing the toilet exits the brickwork. Poor or eroded finishing around pipework (often with mortar or silicone sealants) will let a draught in. If your pipes are not sealed, you are not maintaining the thermal integrity of your house. With harsh winters in the UK now becoming the norm, it is really important that you treat the outside of your property like a ‘skin’ and make sure it is sealed to make it as thermally efficient as possible. Take a look at the outside of your house, where the pipework is. If it is looking weathered or hasn’t been sealed that is the source of your draught.

Look behind your toilet and sink

If your pipework is not tiled or boxed in behind your sink or toilet then look to see if the pipework has been sealed where it leaves the wall. If it hasn’t then the draught will be probably coming in from the external wall where the pipe leaves the house and through this internal gap too.

There is a solution and it doesn’t take long to install. There are no wet trades and it can be fitted in seconds.

Fixing a draught

The most effective and easiest way to prevent draughts and seal around pipes is to use PipeSnug.  Invented by a builder who was fed up of mess and hassle, PipeSnug can be fitted externally and internally, giving a smart finish, quickly. You don’t need to mix mortar or use silicone and it can be fitted in less than five seconds. PipeSnug simply fits into the hole that has been drilled for the pipework and comes in 32mm, 40mm or 110mm sizes.

Before PipeSnug was invented, pipes extruding from buildings were sealed using mortar and also silicone adhesives. This takes time and a lot of effort and eventually weathers, letting draughts through. It is also a hassle to repair ‘like for like’ as mortar has to be mixed up and can really only be used in dry weather. The ‘finish’ mortar provides isn’t the best either, especially if the job is rushed. Although mortar is tough, it is not immune to weathering and can crack and come away, leaving the cracks open to draughts and water damage. Similarly, silicone sealant can also weather, fall away and the finish is not ideal too.

Install a PipeSnug inside and outside

Your plumber or builder should install your PipeSnugs, especially if the pipework is exiting your house outside at height or you need help drilling the wall to clear out the old mortar and sealant.

You can also fit PipeSnugs inside too as they kill the draught and look smarter than alternative means of stopping a draught, like stuffing mineral wool or insulation into a cavity.

Where do I get PipeSnugs from?

PipeSnug pipe seals are available to buy online and in-store from Screwfix and many other retailers across the UK. They can be installed in any weather, do not perish and give a really smart finish. It is a very professional, cost-effective way to make the exterior of a building look smart and aesthetically pleasing.
