New-build mastic & snagging in Dunmore, Falkirk
Professional new build mastic in and around Dunmore, with old sealant always removed completely and a one-year guarantee.
- Gaps opening as the house dries out and settles
- Cracked sealant around new window and door frames
- Gaps between new skirting and floors
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. If you are unsure which you have, email us at info@mrmastic.co.uk with pictures. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

How we handle new build mastic in Dunmore
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. We work on plot handovers, windows & doors and kitchens, and common reasons people get in touch are worktop and upstand sealant coming away and shower seals failing in the first year or two.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
You get a 12-month guarantee, the same in Dunmore as everywhere else we work.

Common questions in Dunmore
Do you cover smaller places like Dunmore?
Yes, Dunmore is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Alloa station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we’ll do.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Do you need new build mastic in Dunmore?
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
These are the problems we’re asked about most:
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
Around Dunmore, as everywhere, new build mastic is only as good as the preparation behind it.

Joints and finishes in Dunmore homes
Dunmore is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Alloa station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the job changes by surface
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.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Open a window or run the fan after bathing
- Look at the sealant regularly in the first couple of years
- Do not seal over failed sealant yourself
- Keep pictures and emails about snagging items
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Quotes for new build mastic in Dunmore
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- The product the joint needs
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
