Commercial sealant in Crosspost
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. Products include Arbo and Everbuild sealants, applied by ARBOMaster approved applicators. If you have failed joints in office kitchens and tea points and black, stained silicone in guest bathrooms, we can help, on hotel bathrooms, retail & leisure sites and office washrooms & kitchens alike.
Somewhere as small as Crosspost, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What affects the quote in Crosspost
There’s no set price list. What we look at:
- The product the joint needs
- How much there is to do
- Any mould that needs treating
- How many areas need sealing
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
- How we’d reach the joints
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Report broken fans quickly
- Encourage users to squeegee shower walls
- Plan resealing around quiet periods
- Tell cleaning staff when each room can be used
We give a cure time for every area we finish, which is usually around 24 hours. Pass it on to housekeeping or cleaners so nobody showers or cleans the joint too early.
A room that can’t be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, before they become leaks that take the room out of use.

Do you need commercial sealant in Crosspost?
Quick fixes come back quickly. Sealing over old silicone, sealing wet joints or using the wrong product all lead to the same thing: another reseal before long.
These are the problems we’re asked about most:
- Silicone laid over old silicone by a previous contractor
- Black, stained silicone in guest bathrooms
- Tired sealant in let properties
- Leaking joints in shower rooms and changing areas
If you look after a building such as Bolney CofE Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.
Before booking anyone
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
- What product goes in the joint
- Whether VAT is included
Leave it or put it right?
Refitting a washroom is a big, disruptive project. When the fittings are sound, renewing the sealant brings it back with far less upheaval. If something else is wrong, we will say so. Around Crosspost, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Colour agreed with you before work begins
- More than 20 years in sealant work
- Sanitary silicone with an anti-fungal additive in wet areas
- Tidy, careful work

What commercial sealant looks like in Crosspost
Crosspost has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.

Your questions about commercial sealant in Crosspost

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Crosspost?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Out-of-hours work and early starts can be arranged. Let us know your hours when you get in touch.
