Commercial & hotel sealant in Alciston, East Sussex
Professional commercial sealant in and around Alciston, with old sealant always removed completely and a one-year guarantee.
- Too many rooms to reseal without closing the building
- Leaks from showers into rooms or ceilings below
- Mouldy washroom sealant that staff and guests notice
Why act early in Alciston
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing will not fix it. Replacing it does. Older cottages and farmhouses around Alciston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for a single washroom, longer for a whole building. Somewhere like Alciston needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We walk the site with you and agree the rooms, the order and the hours.
- Room by room, we protect the area and remove all the old sealant.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Put a squeegee in each shower
- Keep extractor fans working and serviced
- Use mild cleaners on sealant, not bleach or abrasives
- Keep a record of which rooms were resealed and when
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.

How long does commercial sealant take?

Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Certifying fire stopping or building compliance
- Poor ventilation that keeps bringing mould back
- Water coming from plumbing rather than sealant
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
