- A broken extractor fan behind the mould problem
- Faulty shower valves and leaking traps
- Assessing what fire stopping a building needs
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Why deal with it now?
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. We’ll tell you if we find anything that needs another trade. Homes in smaller places like Swaythling can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Signs you need commercial sealant in Swaythling
Larger buildings move, and stud walls move more than solid ones. The sealant between walls, trays and fittings absorbs that strain until it tears.
People generally contact us after spotting something like this:
- Sealant failing again soon after quick repairs
- Tired sealant ahead of a health and safety audit
- Shower leaks reaching the floor below
- Failed joints in office kitchens and tea points
If you look after a church, hall or community building such as St. Mary's Church, its kitchen and washroom sealant needs looking after like anywhere else.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Check the joints during routine room inspections
- Leave squeegees in busy showers
- Check extract fans are actually running
- Tell cleaning staff when each room can be used
Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix, and if anything looks wrong, just call 0345 464 0079 or send us an email.
A room that cannot be let or used is lost income. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.
