Remedial sealant in Hanover
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 have to come out before the joint can be done properly. Typical jobs include sealant peeling off a dusty or damp surface and decorators’ caulk around a bath or shower, across shrunken worktop sealant, expansion joints and mouldy bath & shower sealant.
Even in a smaller place like Hanover, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.

How it works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. For a job in Hanover, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Clear items away from the joints we are working on

Advice
Remedial sealant in Hanover: local notes
Hanover is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to Church of the Annunciation include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Elm Grove Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
Hanover is about 1 mile south of Brighton, in Brighton and Hove. Our applicators cover remedial sealant for homes and businesses in Hanover and nearby. Our Brighton and Hove coverage runs to 30 places, Hanover among them.
Every address in BN2, BN1 and BN50 is within our area for remedial sealant, from the main roads to the quietest streets. If you need remedial sealant at a property on Elmore Road, London Road and Milton Road or a nearby road, we can help. If you are just outside Hanover, we cover Brighton (1 mile north), Carlton Hill (1 mile south), West Hill (1 mile west), Seven Dials (1 mile west) and Kemptown (1 mile south-east). We also work in nearby towns such as Brighton and Hove (3 miles west), Aldrington (3 miles west), Hangleton (3 miles north-west), Patcham (3 miles north), Westdene (3 miles north-west) and Saltdean (4 miles south-east). Being one of Brighton and Hove’s larger places, Hanover has homes, rented property and businesses of every kind.
Landmarks near Hanover
Locally, jobs take us to homes and businesses close to Academy of Creative Training, Brighton Girls and The Dover Castle pub, among other places.

Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. In a smaller place like Hanover, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

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.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
What sealant work cannot fix
We will not take on work that won’t last, so here’s what sealant cannot put right:
- A cracked shower tray or bath (that needs repair or replacing)
- Sealant in an older building that needs testing for asbestos first
- Water damage behind tiles that needs a tiler
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
Surface by surface
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal colour-matched to the worktop.
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint is not the cause, we’ll say so.

Common questions in Hanover
Do you work for hotels and guest houses in Hanover?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Do you cover smaller places like Hanover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can you remove sealant that’s been put over old sealant?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When to call us in Hanover
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
The problems people usually mention when they call include:
- Mould trapped under a layer of silicone
- Wide, uneven beads that look worse than the old ones
- Leaks that keep coming back after resealing
- Products that weren’t meant for the joint
Letting a property close to Brighton station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
