Do you need remedial sealant in Countesswells?
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Keep an eye out for any of the following:
- Products that weren’t meant for the joint
- A shower that leaks however often it’s resealed
- Beads that never stuck properly
- Movement joints that have split or pulled away
If you let a flat or house near Aberdeen station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Before booking anyone
- When the joint can take water or movement
- Whether VAT is included
- What happens if they find a problem under the old sealant
- What preparation is included
Remedial sealant for homes and businesses in Countesswells
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We are often asked to deal with sealant peeling off a dusty or damp surface and smears and lumps from a botched reseal, across expansion joints, mouldy bath & shower sealant and failed movement joints.
For a place like Countesswells, the job is the same as anywhere: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
Big or small, you get the same 12-month guarantee.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Movement from fittings that aren’t supported
- Cracks in the fitting rather than the joint
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

How the visit works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a place like Countesswells, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Do you cover smaller places like Countesswells?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What should I tell you?
Let us know what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What if resealing will not fix my leak?
That is why we look for the cause first. If the fault is elsewhere, you will know before any work is done.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
How we quote for remedial sealant
Your quote is based on your job. We look at:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- How much there is to do
- How easy the joints are to reach
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
What to tell us when you ask for a quote:
- The address or postcode of the job
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Looking after it afterwards
Looking after new joints is easy:
- Deal with small splits early
- Don’t add new sealant on top of old
- Get the cause of a repeat leak found before resealing
- Air the bathroom so the sealant can dry
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
Countesswells homes and their sealant
Aberdeen, the Granite City, has plenty of granite tenements, and in a tenement, a failed seal can reach the flat below. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
Homes close to Church Of Scotland include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Managing a site like Hazlehead Academy? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
