Remedial sealant & repairs in Blacknest, Hampshire
Our applicators work in Blacknest on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Worktop sealant that has shrunk and split
- Movement joints that have split or pulled away
- Repeat leaks from the same joint
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Check trays and worktops don’t move
- Don’t add new sealant on top of old
- Clean sealant with mild products only
- Air the bathroom so the sealant can dry
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just call 0345 464 0079 or send us an email.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
How we handle remedial sealant in Blacknest
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out. We work on failed movement joints, botched or over-sealed joints and leaking tray & enclosure joints, and common reasons people get in touch are wide, uneven beads that look worse than the old ones and worktop sealant that has shrunk and split.
For a small place like Blacknest, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
All our work comes with our one-year guarantee, wherever you are in Hampshire.

What happens if it’s left?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Older cottages and farmhouses around Blacknest can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. Somewhere like Blacknest needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Signs you need remedial sealant in Blacknest
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:
- Floor or wall movement joints that have failed
- Thick, messy sealant smeared over tiles
- Over-sealed joints coming away
- Sealant that came away because the surface wasn’t prepared

What the job involves on each surface
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.

Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- Which sealant suits the joint
- The number and length of the joints
- When we can work, for business premises
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
