Plot mastic for developers and snagging failed sealant in new homes in Greenhill, with a one-year guarantee on every job. Ask us for a quote.
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
- Gaps opening as the house dries out and settles
Keeping the joints in good condition
So the new joints stay in good condition:
- Check bath and shower seals every few months as the house settles
- Keep pictures and emails about snagging items
- Ventilate bathrooms well, especially in the first year
- Put sealant faults on your snagging list early
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
How we handle new build mastic in Greenhill
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. Both get the same care over preparation, because that is what rushed new-build sealant normally lacks. We work on windows & doors, kitchens and skirting & floors, and people most often call us about untidy sealant flagged on a snagging list and sealant work across a run of new homes.
For a place like Greenhill, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Your questions about new build mastic in Greenhill
Can you help a landlord with a rental near Camelon station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is Greenhill within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
How long should I leave it?
It depends on the product. Before we leave, we’ll tell you the cure time.
What sealant work can’t fix
To be straight with you, there are a few things sealant won’t fix:
- Broken tiles or a split tray
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
What we seal
- Show homes
- Bathrooms & en suites
- Plot handovers
- Skirting & floors
- Windows & doors
- Kitchens
Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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, and the work is guaranteed for a year.
For landlords and businesses
If you manage several properties in or around Greenhill, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
Housing providers, facilities teams and property managers book us too in Greenhill and across Falkirk. We can quote a run of properties together, and we’re fully insured for the work.
What affects the cost of new build mastic
You’ll get a clear quote before work begins. It’s based on:
- The number and length of the joints
- Which sealant suits the joint
- Whether the work is at height
- The old material and how stubborn it is
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
What we need to know
When you call or email, it’s useful to know:
- What’s wrong with the joints now
- How we’d reach the joints
- Where the property is
- The rough size of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, email us at info@mrmastic.co.uk.
