About our remedial sealant in Southgate
In Southgate, as anywhere, remedial jobs tend to look alike: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. Typical jobs include repeat leaks from the same joint and a second bead peeling off the first, across failed movement joints, botched or over-sealed joints and mouldy bath & shower sealant.
In a smaller place like Southgate, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In an older home around Southgate, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

- Anti-fungal sanitary silicone in wet areas

Bathrooms and kitchens in Southgate
Crawley, which Southgate is part of, is one of England’s post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. Sealant laid over old sealant never bonds properly, so it all has to come out. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For an older house near a landmark such as St Mary's, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as Southgate Primary, we reseal washrooms and kitchens in schools and businesses as well as homes.

Do you need remedial sealant in Southgate?
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Common reasons people contact us are:
- Sealant peeling off a dusty or damp surface
- Gaps opening along the back of the worktop
- Decorators’ caulk around a bath or shower
- Over-sealed joints coming away
For landlords with property near Crawley station, a joint that keeps failing is best fixed properly while the property is empty.

Questions from Southgate
Do you work for landlords with property near Crawley station?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Is it worth replacing old sealant in an older home in Southgate?
If it hasn’t been replaced for some years, it’s normally worth it. Sealant does not last for ever, and its life depends on use, cleaning and weather, and many homes in Southgate may already be on their second or third set.
Can you reseal a split movement joint?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you fix a reseal that hasn’t worked?
Yes. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
How long does the work take?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. We will give you a timescale when we quote.
The process
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours, depending on how many layers have to come out in most cases. A visit to Southgate is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
