Remedial sealant for homes and businesses in Greenlaw
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. We are often asked to deal with sealant that came away because the surface wasn’t prepared and dark patches showing through the sealant, on botched or over-sealed joints, failed movement joints and leaking tray & enclosure joints.
In and around a place like Greenlaw, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Whatever the size of the job, it’s backed by our 12-month guarantee.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Honest limits
New sealant can’t fix everything, and we will tell you before we start. It will not solve:
- Failed tanking or loose tiles behind the sealant
- Movement from fittings that aren’t supported
- Older mastics that may need an asbestos check before removal
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Expansion joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
Why act early in Greenlaw
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing generally puts it right. Where something else has failed, you’ll hear it from us. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

Common problems we fix in Greenlaw
Joint depth matters. 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.
If you can see any of these, it’s time to have the joints looked at:
- Floor or wall movement joints that have failed
- Decorators’ caulk around a bath or shower
- Sealant applied over old sealant that has lifted
- Sealant that came away because the surface wasn’t prepared
In the older streets around Greenlaw Parish Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Can you remove old sealant without damaging the bath?

Not at all. The area is protected while we work and cleaned up afterwards.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Greenlaw and the rest of the Scottish Borders.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
How it works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. The work generally takes a few hours for a typical bath or shower, longer where several layers have been applied. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Mention any tricky access
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

Remedial sealant around Greenlaw
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out. Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Never fill a movement joint with mortar or grout
- Keep an eye on the ceiling below the bathroom
- Don’t wait for a small gap to become a leak
- Keep bleach and abrasives off the bead
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
