About our commercial sealant in High Cross
For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. Several addresses can go on one quote. Common call-outs are for shower leaks reaching the floor below and too many rooms to reseal without closing the building, on student & care accommodation, hotel bathrooms and retail & leisure sites.
If you have holiday lets, a converted barn used for business or a community building near High Cross, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Why act early in High Cross
Room by room, the work is quick: it takes a morning for a small washroom, and a planned programme for bigger sites. Each area is then left to cure for the time we give you, so planning the order matters more than the hours on site. In a small place like High Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Common questions in High Cross
Do you cover High Cross for commercial sealant?
Yes, High Cross is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Can you help a landlord with a rental near Hassocks station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you work outside opening hours?
In many cases. Tell us your opening hours and quiet times, and we’ll plan the work around them.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
When can guests or staff use the shower again?
Plan for around 24 hours, or the cure time we give for that area. Planning the order of rooms keeps that downtime manageable.
What does commercial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Can you reseal every bathroom in a hotel?
Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Signs you need commercial sealant in High Cross
A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product all lead to the same thing: another reseal before long.
The most common problems we see are:
- Split sealant where wet room floors meet walls
- Sealant failing again soon after quick repairs
- Mouldy washroom sealant that staff and guests notice
- Tired sealant ahead of a health and safety audit
Schools such as Albourne CofE Primary School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.

Workplaces and buildings in High Cross
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Hassocks station, we can quote for one property or a whole portfolio of rentals. If you look after a church, hall or community building such as The Parish Church of St Bartholomew, halls and community kitchens see heavy use, and their sealant shows it.

Advice
How to look after the new joints
Looking after new joints is easy:
- Note the date each area was done
- Tell cleaning staff when each room can be used
- Add sealant to your planned maintenance checks
- Use mild cleaners on sealant, not bleach or abrasives
Squeegees in guest and staff showers help: less water sits on the joints between uses.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.
