How we handle remedial sealant in Hillstreet
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. Typical jobs include gaps opening along the back of the worktop and dark patches showing through the sealant, on mouldy bath & shower sealant, botched or over-sealed joints and failed movement joints.
Being in a small place like Hillstreet makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What remedial sealant looks like in Hillstreet
Hillstreet is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you live in an older home near St Anne's, older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Totton station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
When to call us in Hillstreet
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. At that point it has to come out.
These are the problems we are asked about most:
- Worktop sealant that has shrunk and split
- Decorators’ caulk around a bath or shower
- Black mould underneath the bead
- Sealant peeling off a dusty or damp surface
If you look after a building such as Calmore Junior School, we reseal washrooms and kitchens in schools and businesses as well as homes.

What happens if it’s left?
Another bead over the top will not fix a failed joint. It does not grip the old layer, leaving the leak in place and one more layer to cut out later. Older cottages and farmhouses around Hillstreet can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours, depending on how many layers have to come out. For a village or hamlet like Hillstreet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Move anything stored near the joints
