Good sealant prevents leaks that cause bigger repairs, especially where you rarely see the bathroom yourself.
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. It’s cut out, cleaned and resealed in one neat line.
Commercial sealant in Horsham, done properly
We fit the work around your building. We can work room by room, floor by floor or in batches, and out-of-hours work or early starts can be arranged. We work on hotel bathrooms, office washrooms & kitchens and student & care accommodation, and the jobs we see most are washroom sealant that looks dirty however often it’s cleaned and worktop sealant that has shrunk and stained.
Landlords with flats and shared houses in Horsham often need both kinds of work: new sealant in bathrooms and kitchens, and fire-rated joints around service openings. We can quote for a single property or a whole portfolio.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the visit works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a morning for a small washroom, and a planned programme for bigger sites in most cases. In Horsham, we work in everything from flats and family homes to offices and hotels. Whichever it is, tell us how to get in, where to park and where the work is.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Move anything stored near the joints

Your questions about commercial sealant in Horsham
Can you do commercial sealant in Horsham?
Yes, Horsham is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
I let a flat near Horsham station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you send RAMS and insurance details for our site?
Tell us what paperwork your site needs, for example RAMS or insurance details, and we will confirm what we can supply with the quote.
How long do rooms need to be out of use?
Plan for around 24 hours, or the cure time we give for that area. A room-by-room programme keeps only a few rooms out at once.
What information do you need?
A short description and the location, plus photos if you have them. If we need more, we will ask.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Horsham and across West Sussex. Several sites can be quoted together, and we are fully insured.
Landlords and agents in Horsham can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Leave it or put it right?
Sealant work is quick by the room: it takes a few hours per area, with larger sites planned over several visits. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. In a large rental market like Horsham, tired sealant leads to tenant complaints about mould, damp and leaks. It’s simpler to sort between tenants than in the middle of a let.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

Aftercare tips
Aftercare is simple:
- Plan resealing around quiet periods
- Leave squeegees in busy showers
- Add sealant to your planned maintenance checks
- Keep extractor fans working and serviced
Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix, and if anything looks wrong, just phone 0345 464 0079 or email us.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.
