- Dark patches showing through the sealant
- Torn expansion joints
- Sealant applied over old sealant that has lifted
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
About our remedial sealant in Kincorth
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you drop us a line at info@mrmastic.co.uk, and say how long ago it was last done. We work on failed movement joints, expansion joints and botched or over-sealed joints, and the jobs we see most are dark patches showing through the sealant and torn expansion joints.
Stone-built tenements are part of every Scottish city, alongside houses and newer flats. With flats above and below, a leak from a tired seal can reach the flat underneath.
Big or small, you get the same one-year guarantee in Kincorth and across Aberdeen.

Kincorth questions
Do you work for landlords with property near Aberdeen station?
Yes, we work for landlords and agents. Just email us at 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 Kincorth flat reach the neighbours below?
Yes, it can. In a tenement, water that gets past failed sealant or cracked grout can run under the bath or tray and through to the ceiling below. It’s worth sorting sealant and grout before it gets that far.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Can you fix a reseal that hasn’t worked?
Yes. There’s normally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
How long does remedial resealing take?
It takes a few hours for a typical bath or shower, longer where several layers have been applied. We will give you a timescale when we quote.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Different surfaces, different methods
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint is not the cause, we will say so.
Kincorth homes and their sealant
Kincorth is within about 2 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Aberdeen, the Granite City, has plenty of granite tenements, and in a tenement, a failed seal can reach the flat below.
For an older house near a landmark such as Ruthrieston South Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. For site and facilities teams at buildings such as Lochside Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Kincorth is about 2 miles south of Aberdeen, in Aberdeen. Homes, rented property, offices and hotels in Kincorth can book us for remedial sealant, old or new, large or small. Every job comes with our one-year guarantee. Our Aberdeen coverage runs to 63 places, Kincorth among them.

Other landmarks nearby include Aberdeen Trades Hospitals (1.9 miles north) and Union Square Aberdeen (1.7 miles north). Open spaces near Kincorth include Kincorth Hill and Upper Lake.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Deal with small splits early
- Ask why a joint failed before redoing it
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
Keep the room ventilated: use the extractor or open a window after showering.
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.
Landlords, agents and businesses in Kincorth
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured for the work.
Signs you need remedial sealant in Kincorth
Movement tears sealant that is not designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
The most common problems we see are:
- Wide, uneven beads that look worse than the old ones
- Sealant applied over old sealant that has lifted
- Sealant that came away because the surface wasn’t prepared
- Products that weren’t meant for the joint
For landlords with property near Aberdeen station, a joint that keeps failing is best fixed properly while the property is empty.

The process
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours, depending on how many layers have to come out. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Kincorth, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
