Remedial sealant in Stonehouse, done properly
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you have dark patches showing through the sealant and torn expansion joints, we can put it right, on failed movement joints, expansion joints and botched or over-sealed joints alike.
Being further from a city doesn’t change the work: 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.
All our work is covered by a 12-month guarantee.

How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours, depending on how many layers have to come out from start to finish. For a place like Stonehouse, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Tell us if parking is tricky
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

Advice
What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Movement from fittings that aren’t supported
- Cracks in the fitting rather than the joint
- Leaks from a shower valve, waste or pipework (a plumber’s job)
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

How the job changes by surface
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint is not the cause, we’ll say so.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.
What we’re called out for in Stonehouse
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
These are the problems we are asked about most:
- Products that weren’t meant for the joint
- Repeat leaks from the same joint
- Sealant peeling off a dusty or damp surface
- Worktop sealant that has shrunk and split
For an older house near a landmark such as Stonehouse Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What affects the quote in Stonehouse
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Which sealant suits the joint
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, and we’ll explain the quote if you ask.
Asking for a quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- The address or postcode of the job
- The problem you’ve noticed
- Any access issues, like height or stairs
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we’ll take it from there.
Remedial sealant in Stonehouse: local notes
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. 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.
For landlords with property near Larkhall station, a joint that keeps failing is best fixed properly while the property is empty.

Stonehouse: your questions answered
Is Stonehouse within the area you cover?
Yes, Stonehouse is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Stonehouse in your area for remedial sealant?
Yes, Stonehouse is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Is remedial work guaranteed?
Yes, with our one-year guarantee. Where we have flagged another fault, it needs fixing for the joint to last.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
