About our remedial sealant in Hirst
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. We’re often asked to deal with wide, uneven beads that look worse than the old ones and beads that never stuck properly, on mouldy bath & shower sealant, shrunken worktop sealant and botched or over-sealed joints.
In and around a place like Hirst, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Your questions about remedial sealant in Hirst
Can you help a landlord with a rental near Shotts station?
Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is Hirst within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What does remedial sealant cost?
It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
How long does the work take?
Allow a few hours for most joints, depending on how much old sealant has to come out. You’ll know the timing when we quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Hirst.
What remedial sealant looks like in Hirst
Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in. 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 Hirst, as everywhere, remedial sealant is only as good as the preparation behind it.

What affects the cost of remedial sealant
We quote each job individually. These are the things that affect it:
- The type of sealant required
- The old material and how stubborn it is
- Whether the work is at height
- Working hours on commercial sites
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. Call for a quick quote and we’ll go through it with you.
What we need to know
To help us quote quickly, please include:
- The problem you’ve noticed
- Any previous sealing or DIY work
- The type of property
- A few pictures by email, if you can
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
What sealant work cannot fix
It helps to know what we can’t do too:
- Water damage behind tiles that needs a tiler
- A bath, tray or worktop that moves until it’s properly fixed
- Older mastics that may need an asbestos check before removal
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Failed movement joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Expansion joints
How it works
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours, depending on how many layers have to come out. For a place like Hirst, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by checking the joint for movement, leaks and the reason it failed.
- 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.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, send an email to info@mrmastic.co.uk.
Advice
Common problems we fix in Hirst
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
The most common problems we see are:
- Beads that never stuck properly
- Mould trapped under a layer of silicone
- Over-sealed joints coming away
- Caulk or the wrong sealant used in a wet area
If you let a flat or house near Shotts station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
What your quote should include
- How long to leave it before use
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- What guarantee comes with the work
Also in Hirst
Why act early in Hirst
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around Hirst, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in Hirst
- Fully insured
- Old sealant always removed completely
- Anti-fungal sanitary silicone in wet areas
- A 12-month guarantee on all work

Landlord and commercial work in Hirst
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Different surfaces, different methods
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed in a colour to suit.
