Different surfaces, different methods
Retail & leisure sites
Gym and leisure changing rooms take heavy use and plenty of water, so anti-fungal sanitary silicone is the product we use.
Hotel bathrooms
In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
Common problems we fix in Harold Hill
Heavy use means more movement: different weights, constant use and daily cleaning all work at the joint. If a tray flexes, the sealant around it splits.
Keep an eye out for any of the following:
- Rental bathrooms that need resealing between tenants
- Worktop sealant that has shrunk and stained
- Washrooms that need sorting before an inspection
- Shower leaks reaching the floor below
Managing a site like Drapers' Pyrgo Priory School? Then washroom and kitchen sealant can be programmed around term times or opening hours.

Quotes for commercial sealant in Harold Hill
Call for a quick quote. What matters most is:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- Whether there’s mould to deal with
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Where the property is
- The type of property
- Pictures of the joints, sent by email
- Roughly how big the job is
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.
When something else is needed
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Leaking pipework, valves or wastes (a plumber’s job)
- Extraction that is not working, which needs an electrician or ventilation contractor
- Failed tanking or loose tiles behind the sealant
If you’re not sure, just call 07833 053749 or email us and we’ll give you a straight answer.
Surfaces we seal

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes as long as the scope needs, from one welfare room to a full building. For a job in Harold Hill, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we visit and agree the scope, the sequence and the working hours.
- Every area is sheeted and the old silicone stripped out.
- We clean the joints, treat any mould and let them dry.
- New sealant suited to each area is applied and tooled.
- Each room is checked and handed back with its cure time.
Preparing for the visit
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. London has hard water, which leaves limescale on sealant, grout and taps.
As a London address, Harold Hill can be tricky for parking: let us know about parking bays, permits or a driveway. Community buildings like St Paul are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

Looking after it afterwards
So the new joints stay in good condition:
- Keep strong chemicals and scourers off the joints
- Book larger programmes for quieter times of year
- Leave squeegees in busy showers
- Report broken fans quickly
A squeegee in each shower is a simple help: walls and trays dry faster, and so does the sealant.
It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.
