New Build Mastic in Dunnet
Problem with your new-build sealant joints in Dunnet? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
New build mastic in Dunnet, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. We work on windows & doors, plot handovers and kitchens, and people most often call us about frame joints opening as the plaster dries and untidy sealant flagged on a snagging list.
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.
Whatever the size of the job, it’s backed by our one-year guarantee.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated pictures
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day to cure enough for use.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home, and the area is left clean. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

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 need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
For landlords and businesses
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How the job changes by surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Dunnet questions
Is there a guarantee on new build mastic in Dunnet?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Dunnet within the area you cover?
Yes, Dunnet is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Joints and finishes in Dunnet homes
Dunnet is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For jobs in and around Dunnet, choosing the right material for each joint is as important as a tidy finish.

Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. In an older home around Dunnet, damp from a failed joint can get into timber and plaster.

Signs you need new build mastic in Dunnet
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
These are the problems we’re asked about most:
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
Around Dunnet, as everywhere, new build mastic is only as good as the preparation behind it.
