Remedial Sealant in Mochrum
Our applicators work in Mochrum on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Black mould underneath the bead
- Kitchen joints letting water behind the worktop
- Sealant peeling off a dusty or damp surface
When to call us in Mochrum
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Look out for these signs:
- Leaks that keep coming back after resealing
- Products that weren’t meant for the joint
- Beads that never stuck properly
- Mould trapped under a layer of silicone
Homes close to Kirk of Mochrum include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

How we handle remedial sealant in Mochrum
The wrong product in the wrong joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on shrunken worktop sealant, botched or over-sealed joints and failed movement joints, and people most often call us about over-sealed joints coming away and gaps opening along the back of the worktop.
In and around a place like Mochrum, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
Big or small, you get the same one-year guarantee.

Should I try it myself first?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Different surfaces, different methods
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, and we will tell you if we find it.
What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Common questions in Mochrum
Will you come out to Mochrum?
Yes, Mochrum is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Mochrum in your area for remedial sealant?
Yes. We work across all of Scotland, and Mochrum is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
What if the leak is not the sealant?
That is why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you take off two layers of silicone?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
Why it’s worth doing now in Mochrum
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. 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.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Mochrum homes and their sealant
Mochrum is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. 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.
Around Mochrum, as everywhere, remedial sealant is only as good as the preparation behind it.
