Our applicators work in Southborough on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a 12-month guarantee.

Remedial sealant for homes and businesses in Southborough
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. We work on expansion joints, leaking tray & enclosure joints and botched or over-sealed joints, and common reasons people get in touch are black mould underneath the bead and floor or wall movement joints that have failed.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Southborough more than a cosmetic job.
There’s a 12-month guarantee on every job.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most joints, depending on how much old sealant has to come out. In a London area like Southborough, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- 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.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Keep children and pets away from the work area

How the job changes by surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We’ll tell you what we find.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed colour-matched to the worktop.
How to look after the new joints
Looking after new joints is easy:
- Check ceilings under showers for marks
- Get the cause of a repeat leak found before resealing
- Run the fan after every shower
- Have loose fittings fixed before resealing
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Remedial sealant in Southborough: local notes
London has hard water, so limescale builds up on sealant, grout and fittings. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
If you look after a building such as Southborough Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Bickley station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. As a London address, Southborough can be tricky for parking: let us know about parking bays, permits or a driveway.

Southborough: your questions answered
Could a tired shower seal in my Southborough flat affect the neighbours below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Is parking an issue for remedial sealant in Southborough?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Can you remove old sealant without damaging the bath?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. We point out any damage that is already there.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Southborough.
Can you take off two layers of silicone?
Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
Can you reseal a split movement joint?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
