Remedial sealant in Cornhill
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. We work on mouldy bath & shower sealant, shrunken worktop sealant and expansion joints, and the jobs we see most are leaks that keep coming back after resealing and thick, messy sealant smeared over tiles.
Scotland’s cities have a lot of flats, from sandstone or granite tenements to modern blocks, as well as houses in the suburbs. Scottish water is generally soft, so limescale is less of a problem than in hard-water areas, but mould still grows into sealant and grout in a steamy bathroom.
We stand behind the work with a one-year guarantee.

Surface by surface
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal colour-matched to the worktop.
When to call us in Cornhill
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Common reasons people contact us are:
- Beads that never stuck properly
- Floor or wall movement joints that have failed
- Black mould underneath the bead
- Leaks that keep coming back after resealing
If you live in an older home near St Ninian's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Bathrooms and kitchens in Cornhill
Cornhill is within about 3 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out.
If you look after a building such as Northfield Academy, we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Aberdeen station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

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 getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The process
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied. Parking in city streets around Cornhill can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints

Cornhill questions
Can you help a landlord with a rental near Aberdeen 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’ll give you a clear price.
Could a leaking bath seal in my Cornhill flat reach the neighbours below?
It can. Tenement floors are generally timber, and water from a failed seal can find its way down to the flat below. Replacing tired sealant early is the simplest way to avoid that.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
Do you have insurance?
Yes. We are fully insured for every job we do.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Why deal with it now?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out. Wind-driven rain gets into any failed joint on the outside of a city building, and in Cornhill, damp can spread through stone and plaster before anyone sees it.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
Why us?
- Any old sealant cut out fully, not covered over
- Neat joints and a tidy finish
- Arbo and Everbuild products
- Anti-fungal silicone where joints get wet
