How the job changes by surface
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.
Rental portfolios
Between tenancies is a good time to reseal, so the next tenant moves in to clean, sound joints.
About our commercial sealant in Lewisham
We fit the work around your building. We can work room by room, floor by floor or in batches, and early starts or out-of-hours working can be arranged. If you have washrooms that need sorting before an inspection and shower leaks reaching the floor below, we can help, on welfare facilities, rental portfolios and retail & leisure sites alike.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Lewisham can’t close.
You get a 12-month guarantee, the same in Lewisham as everywhere else we work.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Water damage behind the tiles that needs a tiler or builder
- Poor ventilation that keeps bringing mould back
- Leaking pipework, valves or wastes (a plumber’s job)
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Common questions in Lewisham
Is parking a problem for a job in Lewisham?
Parking in Lewisham, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do you work in hotels near Lewisham?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
How soon can a room be used after resealing?
It depends on the product, but around 24 hours is typical. Housekeeping get the cure time for each room.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you cover Lewisham?
Yes. We’re based in Crawley and work across South East England, London and Scotland, Lewisham included.
Why act early in Lewisham
In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Lewisham, the repair is bigger than a sealant job.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours per room, so whole buildings are phased, depending on the amount of work. In Lewisham, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
