Commercial Sealant in Thorncross
Our applicators work in Thorncross on sealant work for offices, hotels, washrooms and commercial buildings. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Split sealant around staff kitchen worktops and sinks
- Washrooms that need sorting before an inspection
- Shower leaks reaching the floor below
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
About our commercial sealant in Thorncross
Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on student & care accommodation, hotel bathrooms and rental portfolios, and common reasons people get in touch are leaking joints in shower rooms and changing areas and failed joints in office kitchens and tea points.
Work in a small place like Thorncross is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
You get a one-year guarantee, the same in Thorncross as everywhere else we work.

How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours per room, so whole buildings are phased in most cases. Somewhere as small as Thorncross, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Getting ready for the visit
- Mention any parking rules near the property
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- A broken extractor fan behind the mould problem
- A shower tray, bath or basin that is cracked or broken
- Tiles coming off the wall
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Office washrooms & kitchens
- Rental portfolios
- Welfare facilities
- Retail & leisure sites
- Student & care accommodation
- Hotel bathrooms
Aftercare tips
To keep the joints looking good and working properly:
- Tell cleaning staff when each room can be used
- Leave squeegees in busy showers
- Plan resealing around quiet periods
- Ask cleaners to go gently on the silicone
Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Planned resealing is easier to manage than emergency repairs. Rooms can be scheduled around occupancy and staff, rather than closed at short notice.
What affects the quote in Thorncross
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The size of the job
- Which sealant suits the joint
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- If someone has resealed it before
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or drop us an email.
What the job involves on each surface
Rental portfolios
Between tenancies is a good time to reseal, ready for the next tenant.
Office washrooms & kitchens
Office washrooms and tea points are used all day, so the work can be arranged for quieter times. Basins, urinals, worktops and sinks are all resealed.
What commercial sealant looks like in Thorncross
If you run a hotel, guest house or holiday let in a coastal place like Thorncross, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Community buildings like St. Mary's Church are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. Schools such as Brighstone Church of England Aided Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Thorncross questions
Do you cover smaller places like Thorncross?
Yes. Thorncross is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Thorncross in your area for commercial sealant?
Yes. We work across London and the South East, and Thorncross is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Is it messy?
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 supply method statements and risk assessments?
Tell us what your site asks contractors for. We will confirm what we can provide alongside the quote.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is out-of-hours working possible?
Early starts and out-of-hours work can be arranged. Let us know your hours when you get in touch.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What happens if it’s left?
Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Where a wall is exposed, as many are in small places like Thorncross, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
