About our remedial sealant in Murcott
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. Common call-outs are for beads that never stuck properly and worktop sealant that has shrunk and split, on leaking tray & enclosure joints, expansion joints and shrunken worktop sealant.
Being in a small place like Murcott 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.
Each job carries a 12-month guarantee.

When something else is needed
A few problems are outside what sealant work can do:
- Cracks in the fitting rather than the joint
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Plumbing leaks behind walls or under trays
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on

Why deal with it now?
Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Murcott can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Deal with small splits early
- Run the fan after every shower
- Clean sealant with mild products only
- Find out why the sealant failed first
Leave the new joint to cure fully before it gets wet or moves: normally around 24 hours, or as long as we advise.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
Remedial sealant around Murcott
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Around Murcott, as everywhere, remedial sealant is only as good as the preparation behind it. If you let a flat or house near Islip station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

A careful DIYer can reseal a simple joint, 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.
The process
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many layers have to come out. Somewhere as small as Murcott, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

What affects the cost of remedial sealant
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints
- The product the joint needs
- The old material and how stubborn it is
- Whether the work is at height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

You do not need to know the technical terms. It helps if you can tell us:
