What the job involves on each surface
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint isn’t the cause, we will say so.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
Remedial sealant in Bonaly, done properly
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you have black mould underneath the bead and decorators’ caulk around a bath or shower, we can help.
Bathrooms in smaller places like Bonaly work just as hard as those in the cities. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.
Your job is guaranteed for a year, as with all our work.

What happens if it’s left?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

What remedial sealant looks like in Bonaly
Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in. Edinburgh has a lot of tenement flats, in the Old and New Towns and well beyond, and in a tenement, a leaking seal can reach the neighbours below.
Rented homes near Kingsknowe station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Army School of Bagpipe Music and Highland Drumming, we reseal washrooms and kitchens in schools and businesses as well as homes. In the older streets around Colinton Parish Church, walls and floors in older homes can move, and sealant and grout show it first.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Air the bathroom so the sealant can dry
- Check trays and worktops don’t move
- Keep bleach and abrasives off the bead
- Find out why the sealant failed first
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just email us at info@mrmastic.co.uk.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- Older mastics that may need an asbestos check before removal
- Movement from fittings that are not supported
- A leaking trap, valve or supply pipe
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
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.
