Remedial sealant for homes and businesses in Copshaw Holm
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. Typical jobs include a shower that leaks however often it’s resealed and floor or wall movement joints that have failed, across failed movement joints, leaking tray & enclosure joints and expansion joints.
For a place like Copshaw Holm, the job is the same as anywhere: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
Each job carries a 12-month guarantee, whatever its size.

Bathrooms and kitchens in Copshaw Holm
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. In Scotland, private landlords have to meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
In and around Copshaw Holm, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Honest limits
A few problems are outside what sealant work can do:
- A tray or worktop that needs refixing first
- Tiles that have come away from the wall
- Cracks in the fitting rather than the joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Botched or over-sealed joints
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Shrunken worktop sealant
How to look after the new joints
A little care helps the new joints last. Our advice:
- Find out why the sealant failed first
- Act on a lifting corner straight away
- Never seal over old silicone
- Report a tray that rocks or a worktop that lifts
Don’t let anyone seal over it later. New silicone does not bond to old.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Common questions in Copshaw Holm
Do you cover smaller places like Copshaw Holm?
Yes. Copshaw Holm is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.

Yes, Copshaw Holm is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you fix expansion and movement joints?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can old silicone be taken off without scratching the tiles?
Yes, with care. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. We point out any damage that’s already there.
What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job usually takes a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. Outdoor work around Copshaw Holm depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.

Advice
When to call us in Copshaw Holm
Movement tears sealant that is not designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
People usually contact us when they notice something like this:
- Worktop sealant that has shrunk and split
- Repeat leaks from the same joint
- Black mould underneath the bead
- Sealant that came away because the surface wasn’t prepared
For jobs in and around Copshaw Holm, choosing the right material for each joint is as important as a tidy finish.

Surface by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal colour-matched to the worktop.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

We also work for property managers and facilities teams. Several sites can go on one quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
