What the job involves on each surface
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone, accessible showers included.
Office washrooms & kitchens
Office washrooms and tea points are used all day, so the work can be arranged for quieter times. We reseal around basins, urinals, worktops and sinks.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we can’t put right
New sealant cannot fix everything, and we’ll tell you before we start. It won’t solve:
- A broken extractor fan behind the mould problem
- Cracked trays or baths rather than failed joints
- Leaking pipework, valves or wastes (a plumber’s job)
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

When to call us in Shirley
In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. Any split there can let water through quickly.
The problems people usually mention when they call include:
- Washroom sealant that looks dirty however often it’s cleaned
- Rental bathrooms that need resealing between tenants
- Shower leaks reaching the floor below
- Tired sealant ahead of a health and safety audit
For buildings such as Shirley Parish Church, halls and community kitchens see heavy use, and their sealant shows it.
Questions to ask before booking
- When the joint can take water or movement
- Whether they seal over old material or remove it
- Which colour the sealant will be
- Whether VAT is included
Why it’s worth doing now in Shirley
Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Around Shirley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Why book with us
- More than 20 years in sealant work
- Full insurance on every job
- Any old sealant cut out fully, not covered over
- Neat joints and a tidy finish

What affects the cost of commercial sealant
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- The size of the job
- Access and height
- How much old sealant there is and how hard it is to remove
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Helping us quote

- The rough size of the job
- The problem you’ve noticed
- How we’d reach the joints
- Photos by email, if that’s easy
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes as long as the scope needs, from one welfare room to a full building, depending on how much there is to do.

- Each area is protected and the old sealant cut out completely.
- Joints are cleaned, treated for mould and dried.
