DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Commercial sealant in South Mimms, done properly
Commercial work is planned around the building, not the other way round. Rooms can be done one at a time, floor by floor or in batches, and early starts or out-of-hours working can be arranged. If you are dealing with mouldy bathrooms flagged at a tenancy check and failed floor-level joints in accessible wet rooms, we can put it right, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near South Mimms, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Damaged sanitaryware that needs replacing
- Leaking pipework, valves or wastes (a plumber’s job)
- A broken extractor fan behind the mould problem
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Welfare facilities
- Student & care accommodation
- Hotel bathrooms
- Rental portfolios
- Office washrooms & kitchens
- Retail & leisure sites
When to call us in South Mimms
Plenty of commercial bathrooms have no window at all, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.
Keep an eye out for these signs:
- Water marks on ceilings under bathrooms
- Large numbers of bathrooms needing the same work
- Washrooms that need sorting before an inspection
- Repeated reseals that do not last
If you look after a church, hall or community building such as Church of St Giles, halls and community kitchens see heavy use, and their sealant shows it.
What your quote should include

How the visit works
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a morning for a small washroom, and a planned programme for bigger sites for a typical job. In a small place like South Mimms, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Each room is checked and handed back with its cure time.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
