What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on.

- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Plan for the work area to be out of bounds to pets and children

New build mastic in Dunbar, done properly
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. Typical jobs include beads laid onto grit and dust from the build and internal frame sealant that has split, on show homes, plot handovers and kitchens.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why it’s worth doing now in Dunbar
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Dunbar, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

What affects the quote in Dunbar
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- The size of the job
- Access and height
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- The rough size of the job
- A few pictures by email, if you can
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
Every job is quoted individually. Just drop us a line at info@mrmastic.co.uk with the details.
Looking after it afterwards
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Record problems with dated photos
- 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 they’re simple to reseal once movement has slowed.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
What the job involves on each surface
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
Do you need new build mastic in Dunbar?
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
The problems people usually mention when they call are:
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
- Joints pulling apart as timber shrinks
- Gaps behind new kitchen upstands
In and around Dunbar, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- What happens if the job turns out different
- Who does the work, and how experienced they are
- When the joint can take water or movement
- Is the old sealant removed completely?
Joints and finishes in Dunbar homes
Dunbar is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Dunbar station, it’s worth checking the sealant early, while snags are still fresh.
