Remedial sealant in Hunsdon, done properly
If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. Typical jobs include over-sealed joints coming away and black mould underneath the bead, on shrunken worktop sealant, leaking tray & enclosure joints and mouldy bath & shower sealant.
Being in a small place like Hunsdon makes no difference to the job itself: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Each job carries a 12-month guarantee, large or small.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Hunsdon 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.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

What the job involves on each surface
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated.
Leave it or put it right?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Older cottages and farmhouses around Hunsdon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

What information do you need?
Let us know what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
How much does remedial sealant cost in Hunsdon?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you fix a reseal that hasn’t worked?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Common problems we fix in Hunsdon
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Most people get in touch after spotting one of these:
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
- Sealant applied over old sealant that has lifted
- Smears and lumps from a botched reseal
Homes close to St Francis Chapel include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
