DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, 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.
About our remedial sealant in Lochwinnoch
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. We work on mouldy bath & shower sealant, botched or over-sealed joints and shrunken worktop sealant, and the jobs we see most are products that weren’t meant for the joint and beads that never stuck properly.
Being further from a city does not change the work: old material out, joints cleaned and dried, and a fresh, even finish. The journey and access are simply planned in advance.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Lochwinnoch homes and their sealant
In Scotland, private landlords have to 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. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
Rented homes near Lochwinnoch station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

Landlord and commercial work in Lochwinnoch
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Aftercare tips
After the cure time, these simple habits help:
- Keep an eye on the ceiling below the bathroom
- Act on a lifting corner straight away
- Clean sealant with mild products only
- Ask why a joint failed before redoing it
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. Outside jobs in Lochwinnoch need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height

Honest limits
New sealant cannot fix everything, and we will tell you before work begins. It will not solve:
- A leaking trap, valve or supply pipe
- Older mastics that may need an asbestos check before removal
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
Surfaces we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
When to call us in Lochwinnoch
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
The most common problems we see are:
- A second bead peeling off the first
- A shower that leaks however often it’s resealed
- Sealant peeling off a dusty or damp surface
- Movement joints that have split or pulled away
Around Lochwinnoch, as everywhere, remedial sealant is only as good as the preparation behind it.
Questions to ask before booking
- Who turns up on the day
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
Lochwinnoch: your questions answered
Will you come out to Lochwinnoch?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Lochwinnoch in your area for remedial sealant?
Yes. Our work covers the whole of Scotland, and Lochwinnoch is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
What sealant 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.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
What affects the cost of remedial sealant
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- Any working-time requirements on site
- Whether there’s mould to deal with
- How easy the joints are to reach
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
