Our applicators work in North Kelvinside on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Torn expansion joints
- Kitchen joints letting water behind the worktop
- Dark patches showing through the sealant
What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. Inside a flat in North Kelvinside, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- 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.
Before we arrive
- Clear the area around the work
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Remedial sealant in North Kelvinside
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have mould trapped under a layer of silicone and thick, messy sealant smeared over tiles, we can put it right, whatever the surface.
North Kelvinside is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Rooms like that are often small and slow to dry out, which is hard on sealant and grout.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Landlord and commercial work in North Kelvinside
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.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Another bead over the top won’t fix a failed joint. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. For landlords in North Kelvinside, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.

Common questions in North Kelvinside
I let a flat near Possilpark & Parkhouse station. Can you help?
Yes, we work for landlords and agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Could a leaking bath seal in my North Kelvinside flat reach the neighbours below?
It can. Tenement floors are generally timber, and water from a failed seal can find its way down to the flat below. It’s worth sorting sealant and grout before it gets that far.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Can you match the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What we’re called out for in North Kelvinside
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
People normally contact us after spotting one of these:
- Mould trapped under a layer of silicone
- Products that weren’t meant for the joint
- Smears and lumps from a botched reseal
- Torn expansion joints
If you let a flat or house near Possilpark & Parkhouse station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

North Kelvinside homes and their sealant
In Scotland, private landlords have to meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies. Sandstone tenements are a big part of Glasgow’s housing, where most bathrooms sit above another flat.
For site and facilities teams at buildings such as College of Piping, we reseal washrooms and kitchens in schools and businesses as well as homes.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Do not add new sealant on top of old
- Keep movement joints clear of mortar and paint
- Get the cause of a repeat leak found before resealing
- Have loose fittings fixed before resealing
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
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.
