What happens if it’s left?
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 will tell you if we find anything that needs another trade. Older cottages and farmhouses around Harpsden Bottom can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

What else we do in Harpsden Bottom
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Pass on the cure time to whoever cleans the rooms
- Add sealant to your planned maintenance checks
- Schedule work around occupancy
- Encourage users to squeegee shower walls
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant, with stronger products kept off the bead.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, and only replacement fixes it.
What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours for a single washroom, longer for a whole building for a typical job. Somewhere as small as Harpsden Bottom, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

Advice
Honest limits
Before you book, it’s worth knowing the limits:
- Certifying fire stopping or building compliance
- Cracked trays or baths rather than failed joints
- Poor ventilation that keeps bringing mould back
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
- Office washrooms & kitchens
- Rental portfolios
- Student & care accommodation
- Hotel bathrooms
- Retail & leisure sites
- Welfare facilities
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Signs you need commercial sealant in Harpsden Bottom
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. Any split there can let water through quickly.
Any of these means the joints need attention:
- Joints that need doing before an inspection or audit
- Silicone laid over old silicone by a previous contractor
- Water marks on ceilings under bathrooms
- Rental bathrooms that need resealing between tenants
For site and facilities teams at buildings such as Gillotts School, washroom and kitchen sealant can be programmed around term times or opening hours.
