Remedial sealant for homes and businesses in Netherton
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We work on expansion joints, botched or over-sealed joints and mouldy bath & shower sealant, and the jobs we see most are gaps opening along the back of the worktop and thick, messy sealant smeared over tiles.
In Scotland’s cities, including the area around Netherton, 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 are covered after we’ve gone.

How to look after the new joints
To keep the joints looking good and working properly:
- Ask why a joint failed before redoing it
- Use a soft cloth, not a scourer, on silicone
- Act on a lifting corner straight away
- Never seal over old silicone
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How we quote for remedial sealant
Every job gets its own quote. These are the things that affect it:
- Any mould that needs treating
- The number and length of the joints
- The old material and how stubborn it is
- When we can work, for business premises
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
When you call or email, it’s useful to know:
- Photos by email, if that’s easy
- What’s wrong with the joints now
- Roughly how big the job is
- Where the property is
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, email us at info@mrmastic.co.uk.
Surface by surface
Worktops & kitchens
Kitchen joints hold grease and residue, so cleaning takes longer than in a bathroom.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
Bathrooms and kitchens in Netherton
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out. Sandstone tenements are a big part of Glasgow’s housing, where most bathrooms sit above another flat.
For landlords with property near Westerton station, a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near Knightswood St Margaret's Parish Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as Knightswood Secondary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
