How we handle commercial sealant in Harvel
Office kitchens, staff washrooms and welfare facilities need to be usable every working day. Early starts and out-of-hours work can be arranged so the working day is disturbed as little as possible. You’re told when each area can be used again. If you are dealing with mouldy bathrooms flagged at a tenancy check and split sealant around staff kitchen worktops and sinks, we can put it right.
In a village or hamlet like Harvel, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Add sealant to your planned maintenance checks
- Encourage users to squeegee shower walls
- Keep strong chemicals and scourers off the joints
- Report broken fans quickly
Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and that is what keeps mould away.
Signs to look for: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.
Surface by surface
Welfare facilities
Staff welfare areas are needed every shift. Work can be split into sections so some facilities stay open.
Hotel bathrooms
In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Related advice
What commercial sealant looks like in Harvel
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a church, hall or community building such as Church of Our Lady of the Meadow, any kitchen and washrooms need the same sealant care as any other building. Schools such as Culverstone Green Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
