Remedial sealant & repairs in Kingsknowe, Edinburgh
Removing failed, mouldy or leaking sealant and putting it right for householders, landlords and businesses in Kingsknowe. Fully insured, ARBOMaster approved and guaranteed for a year.
- Sealant that came away because the surface wasn’t prepared
- Black mould underneath the bead
- Sealant applied over old sealant that has lifted
How the job changes by surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we’ll point out.
Remedial sealant for homes and businesses in Kingsknowe
Remedial jobs in Kingsknowe normally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. If you are dealing with sealant that came away because the surface wasn’t prepared and sealant applied over old sealant that has lifted, we can put it right, whatever the surface.
Kingsknowe 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.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Kingsknowe: your questions answered
Can you help a landlord with a rental near Kingsknowe station?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Could a leaking bath seal in my Kingsknowe flat reach the neighbours below?
Yes, and the first sign is often a mark on the ceiling below. Cutting out the old sealant and laying a fresh bead puts a stop to it.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
My shower still leaks after a reseal. Can you sort it?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
How long does remedial resealing take?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. We’ll give you a timescale when we quote.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Landlord and commercial work in Kingsknowe
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Letting agents and landlords in Kingsknowe can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
Aftercare tips
So the new joints stay in good condition:
- Never fill a movement joint with mortar or grout
- Keep the room well ventilated
- Ask why a joint failed before redoing it
- Check trays and worktops don’t move
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just drop us a line at info@mrmastic.co.uk.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
What remedial sealant looks like in Kingsknowe
In Scotland, private landlords have to 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, where a failed seal can soon reach the flat below.
If you let a flat or house near Kingsknowe station, botched sealant from a previous quick fix is easier to strip out between tenants.
Kingsknowe is about 3 miles south-west of West End, in Edinburgh. From the centre of Kingsknowe to the outskirts, remedial sealant is available for homes and businesses alike. Our area takes in 175 places across Edinburgh, large and small.
Here we cover the EH14, EH13 and EH11 postcode area for remedial sealant. If you need remedial sealant at a property on Lanark Road, Redhall Road and Hailes Avenue or anywhere close by, our applicators can take on the job. We also cover the places around Kingsknowe: Longstone (1 mile north), Redhall (1 mile north-east), Parkhead (1 mile north), Clovenstone (1 mile south-west) and Wester Hailes (1 mile west).

Around Kingsknowe
Around Kingsknowe, our work takes us to homes and buildings near Firrhill High School, Cross Keys Tavern and Saughton Park. There’s a railway station in Kingsknowe itself: Kingsknowe station. A little further out are Craiglockhart Hydropathic (0.9 miles east) and Merchiston Tower (2.2 miles north-east). Not far away are Duddingston Loch and Craiglockhart Hill.
The process
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Kingsknowe, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Tell us about any water getting in
- Clear the area around the work
- On commercial sites, let us know about site rules

What affects the cost of remedial sealant
For a quick quote, just ask. What matters most is:
- The type of sealant required
- Any working-time requirements on site
- Whether the work is at height
- Mould in or behind the old joints
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
Photos help, but a description is a good start. Please mention:
- How many joints, rooms or windows are involved
- The address or postcode of the job
- Any previous sealing or DIY work
- The problem you’ve noticed
We quote each job on its own, so the first step is telling us about yours. Simply email us at info@mrmastic.co.uk and describe the job and send photos if you have them.
Why act early in Kingsknowe
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In a tenement flat in Kingsknowe, 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.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

What we are called out for in Kingsknowe
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
These are the problems we’re asked about most:
- Mould trapped under a layer of silicone
- Torn expansion joints
- Decorators’ caulk around a bath or shower
- Sealant peeling off a dusty or damp surface
For site and facilities teams at buildings such as Merchiston Castle School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before you book
- Who turns up on the day
- What guarantee comes with the work
- Whether all the old sealant comes out first
- How the colour is chosen
