Charlestown questions
Can you help a landlord with a rental near Portlethen station?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is Charlestown within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can you quote for more than one area?
Yes. Just list everything you need.
Looking after it afterwards
Looking after new joints is easy:
- Run the fan after every shower
- Get the cause of a repeat leak found before resealing
- Keep an eye on the ceiling below the bathroom
- Deal with small splits early
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What happens if it’s left?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. In a place like Charlestown, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What remedial sealant looks like in Charlestown
Charlestown 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, 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. Failed sealant around a bath or shower is worth sorting between tenancies.
Rented homes near Portlethen station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. Homes close to St Mary's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
Charlestown is about 4 miles south of Aberdeen, in Aberdeen. We provide remedial sealant to homeowners, landlords and businesses in Charlestown and nearby. Charlestown is one of 63 places in Aberdeen we cover.

Do you need remedial sealant in Charlestown?
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.
It’s worth asking for a quote if you see:
- Torn expansion joints
- Black mould underneath the bead
- Over-sealed joints coming away
- Sealant that came away because the surface wasn’t prepared
For site and facilities teams at buildings such as Lochside Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.

How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. Outdoor work around Charlestown depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
