How we handle remedial sealant in Mortlake
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you have repeat leaks from the same joint and caulk or the wrong sealant used in a wet area, we can help.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

What affects the cost of remedial sealant
For a quick quote, just ask. What matters most is:
- Mould in or behind the old joints
- How easy the joints are to reach
- How many areas need sealing
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.
Asking for a quote
When you contact us, these details help:
- If someone has resealed it before
- Pictures of the joints, sent by email
- The rough size of the job
- Where the job is, and your postcode
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll give you a clear price before any work starts.
Aftercare tips
A little care helps the new joints last. Our advice:
- Have loose fittings fixed before resealing
- Keep an eye on the ceiling below the bathroom
- Never fill a movement joint with mortar or grout
- Ask why a joint failed before redoing it
Do not let anyone seal over it later. New silicone doesn’t bond to old, so the old bead should always come out first.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.

What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In Mortlake, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Clear the area around the work
- Keep children and pets away from the work area
- Mention any parking rules near the property

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Older mastics that may need an asbestos check before removal
- Cracks in the fitting rather than the joint
- Movement from fittings that are not supported
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Shrunken worktop sealant

Mortlake questions
Do you work for landlords with property near Mortlake station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
I live in a flat in Mortlake. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you remove sealant that is been put over old sealant?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
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.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams. Several sites can go on one quote, and we are fully insured for the work.
How the job changes by surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and point out any existing damage.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Remedial sealant in Mortlake: local notes
London’s water is hard, 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, which is why it’s worth fixing early.
Mortlake is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near All Saints' Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Managing a site like Thomson House School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
