New Build Mastic in Greenfoot
Plot mastic for developers and snagging failed sealant in new homes for homeowners, landlords and businesses in Greenfoot. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
Why deal with it now?
The builder is normally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a place like Greenfoot, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

New build mastic in Greenfoot, done properly
Across Greenfoot, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. If you have beads laid onto grit and dust from the build and cracks appearing as a new home settles, we can put it right.
Around smaller Scottish places like Greenfoot, 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- The product the joint needs
- Access and height
- How much there is to do
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- If someone has resealed it before
- The rough size of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
- Do not wait for the house to settle if water is getting through
- Avoid scourers and strong chemicals on sealant
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we can’t put right
We will always be straight with you, so here’s what sealant can’t fix:
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
- Cracked trays, tiles or worktops
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

New homes and floors in Greenfoot
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
For new homes near Gartcosh station, it’s worth checking the sealant early, while snags are still fresh.

The process
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Outside jobs in Greenfoot need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
How long does new build mastic take?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We’ll tell you when we quote.
Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. Once that’s done, or if they will not put it right, we will cut it out and reseal it.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort 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.
Do you need new build mastic in Greenfoot?
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.
Common reasons people contact us are:
- Joints pulling apart as timber shrinks
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
- Shower seals failing in the first year or two
Around Greenfoot, as everywhere, new build mastic is only as good as the preparation behind it.
