How we handle remedial sealant in Sighthill
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. Common call-outs are for movement joints that have split or pulled away and repeat leaks from the same joint, on mouldy bath & shower sealant, expansion joints and botched or over-sealed joints.
In Scotland’s cities, including the area around Sighthill, many older flats had their bathrooms added into small rooms later on. Space is tight and ventilation can be poor, and steam with nowhere to go is what turns sealant black and grout grey.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Sighthill questions
Can a failed shower seal in a tenement flat in Sighthill leak into the flat 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.
Can you help a landlord with a rental near Barnhill station?
Yes. We work for landlords and agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.
How long does the work take?
It takes a few hours, depending on how many layers have to come out. We will give you a timescale when we quote.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, 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 Sighthill, it helps to know the floor, the door entry arrangements and the nearest parking.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Before we arrive
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Different surfaces, different methods
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal with a low-modulus product.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Remedial sealant in Sighthill: local notes
Glasgow has a lot of sandstone tenements, where most bathrooms sit above another flat. 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.
If you let a flat or house near Barnhill station, a joint that keeps failing is best fixed properly while the property is empty.

Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why act early in Sighthill
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. For landlords in Sighthill, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- Experience in homes, commercial sites and hotels
- Quality sealants from Arbo and Everbuild
- You choose the colour before work begins
- We’re fully insured

How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep the room well ventilated
- Do not wait for a small gap to become a leak
- Keep movement joints clear of mortar and paint
- Get the cause of a repeat leak found before resealing
Give the new sealant its full cure time: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
When to call us in Sighthill
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’s too stiff or too thin.
Look out for these signs:
- Wide, uneven beads that look worse than the old ones
- Repeat leaks from the same joint
- Sealant that came away because the surface wasn’t prepared
- Floor or wall movement joints that have failed
If you look after a building such as St. Roch's Secondary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
What your quote should include
- What guarantee comes with the work
- What happens if the job turns out different
- How long to leave it before use
- Is the old sealant removed completely?
