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 black, stained silicone in guest bathrooms and rental bathrooms that need resealing between tenants, we can put it right, on office washrooms & kitchens, hotel bathrooms and student & care accommodation alike.
Work in a small place like Merton is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Merton questions
Do you cover smaller places like Merton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Merton for commercial sealant?
Yes, Merton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
How long does commercial sealant take?
It depends on the size of the job, but as a guide it takes as long as the scope needs, from one welfare room to a full building. We’ll give you a better idea when we quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you work around guests in a hotel?
Normally, yes. The order and timing are agreed with your team, and you will know when each room can be used.
When can guests or staff use the shower again?
Around 24 hours is typical for sanitary silicone. We tell your team the cure time for every area.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Common problems we fix in Merton
Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. Mould then takes hold in the silicone.
Look out for these signs:
- Tired sealant in let properties
- Silicone laid over old silicone by a previous contractor
- Tired sealant ahead of a health and safety audit
- Whole floors of tired en suites
For buildings such as Church of St Swithin, its kitchen and washroom sealant needs looking after like anywhere else.
Questions to ask before you book
- How the colour is chosen
- What happens if they find a problem under the old sealant
- Are they insured?
- How much experience the applicator has
How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep a record of which rooms were resealed and when
- Plan resealing around quiet periods
- Encourage users to squeegee shower walls
- Report broken fans quickly
Keep the extraction running and maintained. Where a room has no window, the fan is what dries it out, and mould comes back faster without it.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.

Student & care accommodation
Empty rooms between terms or tenancies are easy to reseal, but occupied rooms can be planned in as well.
Commercial sealant in Merton: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Leave it or put it right?
A leaking shower in a hotel room or flat above can damage the ceiling below. Then two rooms are out of action, not one. Resealing first is the smaller job. Older cottages and farmhouses around Merton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
