About our remedial sealant in Streatham Hill
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. Common call-outs are for over-sealed joints coming away and repeat leaks from the same joint, across botched or over-sealed joints, leaking tray & enclosure joints and failed movement joints.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Streatham Hill are no different.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What else we do in Streatham Hill
When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
- A tray or bath that is cracked
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
Joints and surfaces we work on
- Failed movement joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
- Expansion joints
- Leaking tray & enclosure joints
When to call us in Streatham Hill
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Any of these means the joints need attention:
- Floor or wall movement joints that have failed
- Sealant that came away because the surface wasn’t prepared
- Smears and lumps from a botched reseal
- Black mould underneath the bead
Homes close to Church of St Margaret include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How the job changes by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we’ll point out.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Find out why the sealant failed first
- Use a soft cloth, not a scourer, on silicone
- Keep the room well ventilated
- Check trays and worktops do not move
Keep the room ventilated: use the extractor or open a window after showering.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Streatham Hill: your questions answered
Do you work for hotels and guest houses in Streatham Hill?
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.
Is parking an issue for remedial sealant in Streatham Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job usually takes a few hours for a typical bath or shower, longer where several layers have been applied, and we tell you how long to leave it before we go. In Streatham Hill, 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.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
