Remedial sealant & repairs in Cults, Aberdeen
Our applicators work in Cults on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Sealant that came away because the surface wasn’t prepared
- Black mould underneath the bead
- Repeat leaks from the same joint
Remedial sealant in Cults, done properly
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you have repeat leaks from the same joint and mould trapped under a layer of silicone, we can put it right, on expansion joints, shrunken worktop sealant and failed movement joints alike.
Scotland’s cities have a lot of flats, from sandstone or granite tenements to modern blocks, as well as houses in the suburbs. Generally soft Scottish water means less limescale, but steam and poor ventilation still let mould into the sealant and grout.
All of our work is guaranteed for twelve months.

Looking after it afterwards
After the cure time, these simple habits help:
- Never fill a movement joint with mortar or grout
- Air the bathroom so the sealant can dry
- Use a soft cloth, not a scourer, on silicone
- Never seal over old silicone
Clean gently: no scraping, scouring pads or harsh chemicals.
Don’t keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Surface by surface
Mouldy bath & shower sealant
Repeat mould normally points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. We remove the failed sealant, fit backing and reseal.
Do you need remedial sealant in Cults?
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.
Look out for any of the following:
- Movement joints that have split or pulled away
- Decorators’ caulk around a bath or shower
- Leaks that keep coming back after resealing
- A second bead peeling off the first
Schools such as Cults Academy are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Before booking anyone

What we do, step by step
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes 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 Cults, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- 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.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
Remedial sealant around Cults
Aberdeen is known for its granite tenements, and in a tenement, a failed seal can reach the flat below. 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.

Questions from Cults
I let a flat near Aberdeen station. Can you help?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Can a failed shower seal in a tenement flat in Cults leak into the flat below?
Yes. With flats above and below, a leak from a failed seal rarely stays in one flat. Cutting out the old sealant and laying a fresh bead puts a stop to it.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Does remedial work come with a guarantee?
Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.
