Why it’s worth doing now in Clermiston
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. In a tenement flat in Clermiston, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

How we handle remedial sealant in Clermiston
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. If you’re dealing with leaks that keep coming back after resealing and caulk or the wrong sealant used in a wet area, we can help, on shrunken worktop sealant, mouldy bath & shower sealant and leaking tray & enclosure joints alike.
Clermiston is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Space is tight and ventilation can be poor, 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’ll sort it.

What happens on the day
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. 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 Clermiston, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Clermiston is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
For landlords with property near South Gyle station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Landlord and commercial work in Clermiston
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Can I do it myself?
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, and the work is guaranteed for a year.
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.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A cracked shower tray or bath (that needs repair or replacing)
- A tray or worktop that needs refixing first
- Failed tanking or loose tiles behind the sealant
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Failed movement joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant

Clermiston questions
Do you work in hotels near Clermiston?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you work for landlords with property near South Gyle station?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can you fix a reseal that hasn’t worked?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
How much does remedial sealant cost in Clermiston?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.

- How many joints, rooms or windows are involved
- A few photos by email, if you can
- Where the job is, and your postcode

Signs you need remedial sealant in Clermiston
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
Look out for any of the following:
- Repeat leaks from the same joint
- Wide, uneven beads that look worse than the old ones
- Caulk or the wrong sealant used in a wet area
- A second bead peeling off the first
If you look after a building such as Craigmount High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
