Addiscombe Commercial Sealant
We cover Addiscombe for sealant work for offices, hotels, washrooms and commercial buildings. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Black, stained silicone in guest bathrooms
- Tired sealant in let properties
- Whole floors of tired en suites
Looking after it afterwards
Looking after new joints is easy:
- Ask cleaners to go gently on the silicone
- Log resealing so you know what’s due
- Act on lifting sealant before it leaks
- Schedule work around occupancy
We give a cure time for every area we finish, generally around 24 hours. Make sure housekeeping or cleaning staff know it so nobody showers or cleans the joint too early.
Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.
Commercial sealant for homes and businesses in Addiscombe
Hotel bathrooms take hard daily use and constant cleaning, so sealant there has a hard life. Rooms are resealed in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. We work on rental portfolios, hotel bathrooms and welfare facilities, and the jobs we see most are mouldy bathrooms flagged at a tenancy check and split sealant around staff kitchen worktops and sinks.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Addiscombe can’t close.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Workplaces and buildings in Addiscombe
London has hard water, which leaves limescale on sealant, grout and taps. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
For buildings such as St Mildred's Church, its kitchen and washroom sealant needs looking after like anywhere else. If you look after a building such as Oasis Academy Shirley Park, busy washrooms and kitchens can be resealed in phases so they stay open.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of rooms. In Addiscombe, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- The first visit is a look round the site to agree the scope.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can

Advice
Common problems we fix in Addiscombe
Staff kitchens and food areas see constant splashing and wiping, so sealant there wears and stains. The worktop and sink edges generally fail first.

- Tired sealant ahead of a health and safety audit
- Split sealant around staff kitchen worktops and sinks
- Mouldy washroom sealant that staff and guests notice
- Whole floors of tired en suites

Addiscombe questions
I let a flat near Norwood Junction station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is Addiscombe in your area for commercial sealant?
Yes. Our work covers London and the South East, and Addiscombe is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you work outside opening hours?
It can be arranged. The hours are agreed before work starts.
What happens if it’s left?
Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Addiscombe.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
