Remedial sealant in Dornoch
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. We’re often asked to deal with sealant peeling off a dusty or damp surface and dark patches showing through the sealant, across mouldy bath & shower sealant, failed movement joints and shrunken worktop sealant.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
You are covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Aftercare tips
To keep the joints looking good and working properly:
- Do not point over movement joints
- Deal with small splits early
- Have loose fittings fixed before resealing
- Keep an eye on the ceiling below the bathroom
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
Remedial sealant around Dornoch
Dornoch is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. 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.
Rented homes near Tain station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most joints, depending on how much old sealant has to come out. Outdoor work around Dornoch depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Tell us about any water getting in

Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Signs you need remedial sealant in Dornoch
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
People normally contact us when they notice one of these:
- Beads that never stuck properly
- Dark patches showing through the sealant
- Gaps opening along the back of the worktop
- Movement joints that have split or pulled away
If you look after a building such as Dornoch Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- How much experience the applicator has
- Whether they seal over old material or remove it

Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed colour-matched to the worktop.
