Why act early in Gosport
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Gosport they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why Gosport clients choose us
- We leave the area clean and tidy
- An ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet
- Full insurance on every job

Remedial sealant in Gosport
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We are often asked to deal with sealant peeling off a dusty or damp surface and torn expansion joints, across expansion joints, mouldy bath & shower sealant and shrunken worktop sealant.
Around Gosport, it’s mostly busy family bathrooms and kitchens, which is hard on sealant and grout. Black mould along the bath, a lifting bead by the sink or crumbling grout in the shower are the usual signs.
There’s a 12-month guarantee on every job, large or small.

How the job changes by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. Along with resealing, we’ll mention if the room needs better ventilation.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- A bath, tray or worktop that moves until it’s properly fixed
- Tiles that have come away from the wall
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Surfaces we seal
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
- Failed movement joints
- Botched or over-sealed joints
What affects the quote in Gosport
Jobs vary more than people expect. The main factors:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- When we can work, for business premises
Doing several joints on one visit usually makes better use of the time than several visits. We will give you a clear price for the lot.

Gosport homes and their sealant
Gosport is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Brockhurst 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 landlords with property near Portsmouth Harbour station, botched sealant from a previous quick fix is easier to strip out between tenants. Homes close to St Faith's Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Does someone need to be in?

What sealant do you use?

When is the sealant fully cured?

Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.

How to look after the new joints
So the new joints stay in good condition:
- Keep bleach and abrasives off the bead
- Don’t wait for a small gap to become a leak
- Get the cause of a repeat leak found before resealing
- Never fill a movement joint with mortar or grout
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
