Common questions in Partick
I let a flat near Partick station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Could a leaking bath seal in my Partick flat reach the neighbours below?
Yes, and the first sign is often a mark on the ceiling below. A proper reseal, with all the old sealant cut out, stops it at the source.
Do you come to Partick?
We do. Our applicators work in Partick, and the service is the same as everywhere else.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, so we find that first.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Can I choose the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
About our remedial sealant in Partick
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that will not fix it. We work on expansion joints, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are a shower that leaks however often it’s resealed and dark patches showing through the sealant.
Partick is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Space is tight and ventilation can be poor, and steam with nowhere to go is what turns sealant black and grout grey.
Each job carries a 12-month guarantee, whatever its size.

When to call us in Partick
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
Signs it’s time to call us include:
- Wide, uneven beads that look worse than the old ones
- Sealant peeling off a dusty or damp surface
- Sealant applied over old sealant that has lifted
- Decorators’ caulk around a bath or shower
If you let a flat or house near Partick station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

The process
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. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Partick, it helps to know the floor, the door entry arrangements and the nearest parking.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
How to get a quote

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What affects the cost of remedial sealant
You will get a clear quote before we start. It takes into account:
- The old material and how stubborn it is
- How easy the joints are to reach
- When we can work, for business premises
- Any mould that needs treating
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Whether it’s a home or a business
- How we’d reach the joints
- Any previous sealing or DIY work
- Where the property is
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved.
What remedial sealant looks like in Partick
Sandstone tenements are a big part of Glasgow’s housing, so many bathrooms sit right above a neighbour’s ceiling. 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.
Schools such as St Peter's Boys School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Partick is about 2 miles north-west of Glasgow, in Glasgow. Partick gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Our Glasgow coverage runs to 183 places, Partick among them.

How the job changes by surface
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal.
Landlord and commercial work in Partick
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.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
When it is not the sealant
We will not take on work that will not last, so here’s what sealant cannot put right:
- Water damage behind tiles that needs a tiler
- Movement from fittings that are not supported
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Botched or over-sealed joints
- Leaking tray & enclosure joints
