Gremista New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for householders, landlords and businesses in Gremista. Fully insured, ARBOMaster approved and guaranteed for a year.
- Beads laid onto grit and dust from the build
- Cracked sealant around new window and door frames
- Sealant work across a run of new homes
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Don’t wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
- Avoid running a DIY bead over the old one
- Keep water off fresh sealant until it has cured
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you so report it promptly.
New build mastic for homes and businesses in Gremista
We work in new homes and on new-build sites across Gremista. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on plot handovers, bathrooms & en suites and show homes, and the jobs we see most are frame joints opening as the plaster dries and beads laid onto grit and dust from the build.
Around smaller Scottish places like Gremista, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
There’s a 12-month guarantee on every job.

What we’re called out for in Gremista
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
Any of these means the joints need attention:
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
- Sealant applied over dusty or wet surfaces
- Messy sealant that spoils new finishes
For jobs in and around Gremista, choosing the right material for each joint is as important as a tidy finish.
Before you book anyone
- How much experience the applicator has
- Which colour the sealant will be
- How long to leave it before use
- How the joint is cleaned and prepared
Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Gremista, water from a failed joint in an older stone home can soak into timber and plaster.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

When it isn’t the sealant
In fairness, some problems need a different trade:

Questions from Gremista
Do you cover Gremista for new build mastic?
Yes. We work across all of Scotland, and Gremista is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is Gremista within the area you cover?
Yes, Gremista is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
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.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

New homes and floors in Gremista

Around Gremista, as everywhere, new build mastic is only as good as the preparation behind it.

Different surfaces, different methods
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
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.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours in a single home, depending on how much there is to do. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Let us know about parking restrictions
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
