How we handle remedial sealant in Winsor
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. If you are dealing with leaks that keep coming back after resealing and smears and lumps from a botched reseal, we can help.
Somewhere as small as Winsor, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
A 12-month guarantee comes as standard.

What we are called out for in Winsor
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing sets the depth and stops that.
Most people get in touch after spotting one of these:
- Movement joints that have split or pulled away
- Products that weren’t meant for the joint
- Sealant that came away because the surface wasn’t prepared
- Kitchen joints letting water behind the worktop
Homes close to Church of St Mary include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What remedial sealant looks like in Winsor
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.
For site and facilities teams at buildings such as Copythorne CofE Infant School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Letting a property close to Ashurst New Forest station? Then a joint that keeps failing is best fixed properly while the property is empty.

Winsor questions
Do you work for landlords with property near Ashurst New Forest station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Winsor?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Are you insured?
Yes. Mr Mastic is fully insured.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
How the job changes by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
How we quote for remedial sealant
For a quick quote, just ask. What matters most is:
- How many areas need sealing
- Mould in or behind the old joints
- How easy the joints are to reach
- Working hours on commercial sites
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- Roughly how big the job is
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Find out why the sealant failed first
- Have loose fittings fixed before resealing
- Do not point over movement joints
- Don’t wait for a small gap to become a leak
Where we have pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Do not keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- A bath, tray or worktop that moves until it’s properly fixed
- A tray or bath that is cracked
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like Winsor, access is normally the main thing to plan. 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.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- 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
- Mention any tricky access
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
