- Kitchen joints letting water behind the worktop

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Clean sealant with mild products only
- Check ceilings under showers for marks
- Keep movement joints clear of mortar and paint
- Act on a lifting corner straight away
Keep the room ventilated: use the extractor or open a window after showering.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Remedial sealant in Winkfield Street, done properly
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. If you are dealing with movement joints that have split or pulled away and kitchen joints letting water behind the worktop, we can help, on failed movement joints, leaking tray & enclosure joints and mouldy bath & shower sealant alike.
In a village or hamlet like Winkfield Street, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.

Where is Mr Mastic based?

My shower still leaks after a reseal. Can you sort it?

DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Water damage behind tiles that needs a tiler
- Cracks in the fitting rather than the joint
- A bath, tray or worktop that moves until it’s properly fixed
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
What we seal
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Expansion joints
- Botched or over-sealed joints
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. Somewhere as small as Winkfield Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What remedial sealant looks like in Winkfield Street
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Martins Heron station, botched sealant from a previous quick fix is easier to strip out between tenants.

Why deal with it now?
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Older cottages and farmhouses around Winkfield Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
