Remedial sealant for homes and businesses in Downham
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. We work on shrunken worktop sealant, botched or over-sealed joints and failed movement joints, and people most often call us about a shower that leaks however often it’s resealed and mould trapped under a layer of silicone.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Downham, that is a good reason to put tired sealant and grout right early.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Aftercare tips
So the new joints stay in good condition:
- Keep an eye on the ceiling below the bathroom
- Get the cause of a repeat leak found before resealing
- Do not add new sealant on top of old
- Report a tray that rocks or a worktop that lifts
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Don’t keep resealing the same joint. Have someone find out why, or the next bead will go the same way.

FAQs for Downham
Do you work for landlords with property near Grove Park station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do you take on hotel work around Downham?

Can you match the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How long does the work take?
That depends on how many layers there are and how many joints. We will tell you before we start.

Yes. We’re based in Crawley and work across South East England, London and Scotland.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Why act early in Downham
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Downham, the repair is bigger than the sealant job would have been.
Leaving a failed joint generally makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Common problems we fix in Downham
One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
People generally contact us after spotting one of these:
- Sealant applied over old sealant that has lifted
- Leaks that keep coming back after resealing
- Products that weren’t meant for the joint
- Thick, messy sealant smeared over tiles
As a London address, Downham can be tricky for parking: let us know about parking bays, permits or a driveway.
Before you book anyone
- What product goes in the joint
- When the joint can take water or movement
- How hidden problems are handled
- Is the old sealant removed completely?

How the job changes by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning before resealing.
