How we handle remedial sealant in Petersfield
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you’re dealing with torn expansion joints and sealant peeling off a dusty or damp surface, we can put it right, whatever the surface.
Plenty of homes in a town like Petersfield have had new bathrooms and kitchens over the years. A common problem is new sealant laid over old, which never bonds properly, which is why all the old material has to come out first.
There’s a 12-month guarantee on every job.

Signs you need remedial sealant in Petersfield
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. At that point it has to come out.
The problems people usually mention when they call include:
- Mould trapped under a layer of silicone
- Decorators’ caulk around a bath or shower
- Worktop sealant that has shrunk and split
- A second bead peeling off the first
If you look after a building such as Petersfield Infant 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.
Questions to ask before booking
- Are they insured?
- What preparation is included
- Whether the sealant suits the joint
- Whether you can choose the colour
Remedial sealant in Petersfield: local notes
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.
If you let a flat or house near Petersfield station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. In the older streets around St Peter's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Can I do it myself?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

I rent my home. Can I book you?

The process
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. For a job in Petersfield, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- 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.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

Advice
How the job changes by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Worktops & kitchens
A loose worktop splits its sealant. That needs refixing before resealing, which we will point out.

Honest limits
In fairness, some problems need a different trade:
- Tiles that have come away from the wall
- Older mastics that may need an asbestos check before removal
- Cracks in the fitting rather than the joint
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant

Why it’s worth doing now in Petersfield
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Petersfield they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
