Remedial sealant in Clapham Junction, done properly
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We are often asked to deal with torn expansion joints and products that weren’t meant for the joint, on botched or over-sealed joints, expansion joints and failed movement joints.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Clapham Junction are no different.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. In Clapham Junction, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit

Advice
What we can’t put right

- Plumbing leaks behind walls or under trays
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What remedial sealant looks like in Clapham Junction
Clapham Junction has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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.
As a London address, Clapham Junction can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Clapham Junction station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Christ Church CofE Primary School, 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.

Common questions in Clapham Junction
Do you work in hotels near Clapham Junction?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can parking be tricky for a visit in Clapham Junction?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Where are you based?
We work from Crawley. We cover Clapham Junction and the rest of Greater London, along with the rest of our area.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before we start.
How do I get a quote for remedial sealant in Clapham Junction?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email and let us know what needs doing and where.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Aftercare tips
After the cure time, these simple habits help:
- Check trays and worktops do not move
- Always have old sealant cut out, not covered
- Get the cause of a repeat leak found before resealing
- Run the fan after every shower
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.

DIY sealant or a professional job?
