What the job involves on each surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
New build mastic in Dundonald, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on skirting & floors, bathrooms & en suites and kitchens, and people most often call us about sealant work across a run of new homes and gaps between new skirting and floors.
Around smaller Scottish places like Dundonald, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
All of our work is guaranteed for twelve months.

What else we do in Dundonald
Dundonald: your questions answered
Do you cover smaller places like Dundonald?
Yes. Dundonald is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Cardenden station?
Yes. We work for letting agents and landlords as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room and agree it with you.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we will do.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Use the extractor fan every time you shower
- Get a leaking seal dealt with right away
- Keep pictures and emails about snagging items
- Report sealant problems to your builder during the snagging period
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
