About our remedial sealant in Glenmavis
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We work on failed movement joints, expansion joints and shrunken worktop sealant, and common reasons people get in touch are thick, messy sealant smeared over tiles and sealant that came away because the surface wasn’t prepared.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
There’s a 12-month guarantee on every job.

What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on how much there is to do. For a place like Glenmavis, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- 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’re told about anything else we found.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

Glenmavis homes and their sealant
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. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
In the older streets around Parish Church, walls and floors in older homes can move, and sealant and grout show it first. Schools such as Airdrie Academy are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Glenmavis is about 2 miles north-west of Airdrie, in North Lanarkshire.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common problems we fix in Glenmavis
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
The most common problems we see are:
- Products that weren’t meant for the joint
- Leaks that keep coming back after resealing
- A second bead peeling off the first
- Beads that never stuck properly
For landlords with property near Coatdyke station, a joint that keeps failing is best fixed properly while the property is empty.

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Why deal with it now?
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 Glenmavis, 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.

Why us?
- Neat joints and a tidy finish

Different surfaces, different methods
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or worktop that needs refixing first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
