Remedial sealant & repairs in Dundonald, East Ayrshire
Remedial sealant across Dundonald and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Movement joints that have split or pulled away
- Caulk or the wrong sealant used in a wet area
- Sealant that came away because the surface wasn’t prepared
How the job changes by surface
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. We rake that out where it can be removed and seal with a flexible product.
Remedial sealant in Dundonald, done properly
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we will tell you rather than reseal something that won’t fix it. Typical jobs include gaps opening along the back of the worktop and floor or wall movement joints that have failed, across leaking tray & enclosure joints, failed movement joints and expansion joints.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Your job is guaranteed for a year, as with all our work.

What else we do in Dundonald
Your questions about remedial sealant in Dundonald
Is Dundonald within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Barassie station. Can you help?
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 give you a clear price.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Dundonald, along with the rest of our area.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Can you strip sealant from an acrylic tray safely?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
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.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What remedial sealant looks like in Dundonald
Dundonald 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. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
Rented homes near Barassie station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. In the older streets around Dundonald Parish Church, older homes can move a little, which is hard on rigid grout and tired sealant.
Dundonald is about 3 miles north-east of Troon, in East Ayrshire. Our applicators cover remedial sealant for homes and businesses in Dundonald and the surrounding area. Our area takes in 53 places across East Ayrshire, from the larger towns to small villages. Glasgow is on our list too, around 23 miles away.
All of KA2 is within our area for remedial sealant. You’ll find streets such as Main Street, Fullarton Avenue and Earl Drive, and we cover them all. Main roads around Dundonald include the A759, so getting to you is simple. We also cover Drybridge (1 mile north), Gatehead (2 miles north-east), Collennan (2 miles south-west), Barassie (2 miles south-west) and Dreghorn (2 miles north-west).

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep movement joints clear of mortar and paint
- Ask why a joint failed before redoing it
- Air the bathroom so the sealant can dry
- Deal with small splits early
Don’t let anyone seal over it later. New silicone doesn’t bond to old, so the old bead should always come out first.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’re 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 doesn’t work out, we can still put it right.
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many layers have to come out. Outside jobs in Dundonald need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We protect the surfaces around the joint.
- 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.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What sealant work cannot fix
We won’t take on work that won’t last, so these are the limits:
- Plumbing leaks behind walls or under trays
- Water damage behind tiles that needs a tiler
- Sealant in an older building that needs testing for asbestos first
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

What affects the cost of remedial sealant
We don’t publish a price list. What we look at:
- Access and height
- Mould in or behind the old joints
- How much there is to do
- When we can work, for business premises
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- The rough size of the job
We don’t publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, send an email to info@mrmastic.co.uk.
