Remedial sealant in East Grinstead from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Remedial sealant in East Grinstead, done properly
Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. We work on failed movement joints, expansion joints and mouldy bath & shower sealant, and the jobs we see most are repeat leaks from the same joint and decorators’ caulk around a bath or shower.
Most bathrooms in a town like East Grinstead are in family homes, used every day, which is hard on sealant and grout. The usual signs are mould in the bead, gaps by the sink and grout that’s cracked or stained.
All our work comes with our one-year guarantee, wherever you are in West Sussex.

When to call us in East Grinstead
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
These are the problems we’re asked about most:
- A shower that leaks however often it’s resealed
- Kitchen joints letting water behind the worktop
- Sealant that came away because the surface wasn’t prepared
- Floor or wall movement joints that have failed
Rented homes near East Grinstead station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- A cracked shower tray or bath (that needs repair or replacing)
- Water damage behind tiles that needs a tiler
- Plumbing leaks behind walls or under trays
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

- How we’d reach the joints

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved.
Different surfaces, different methods
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We say so rather than reseal.
Remedial sealant in East Grinstead: local notes
There are hotels and other places to stay in and around East Grinstead. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you live in an older home near Our Lady and St Peter's Church, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as St Mary's 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.

For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy.
