New build mastic in Newarthill
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you have plot mastic for developers ahead of handover and leaking shower tray seals in a new home, we can put it right.
For a place like Newarthill, 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.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- How many areas need sealing
- When we can work, for business premises
- The number and length of the joints
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.
Asking for a quote
When you call or email, these details help:
- Where the job is, and your postcode
- The rough size of the job
- If someone has resealed it before
- Whether it’s a home or a business
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, send an email to info@mrmastic.co.uk.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Surface by surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
What happens if it’s left?
The builder is generally 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. 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.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Why Newarthill clients choose us
- We leave the area clean and tidy
- White, clear, grey or coloured to suit, where the product allows
- Anti-fungal sanitary silicone in wet areas
- Approved under the ARBOMaster scheme
Common problems we fix in Newarthill
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
People usually contact us when they notice something like this:
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
If you’ve bought a new home near Carfin station, the sealant around baths, showers and frames is worth checking in the first year or two.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep water off fresh sealant until it has cured
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Questions from Newarthill
I let a flat near Carfin station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Is Newarthill within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
