About our new build mastic in Neilston
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you’re dealing with beads laid onto grit and dust from the build and leaking shower tray seals in a new home, we can help, on plot handovers, windows & doors and show homes alike.
Around smaller Scottish places like Neilston, 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Different surfaces, different methods
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.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
What affects the cost of new build mastic
We don’t publish a price list, because jobs vary so much. What we look at:

- Any mould that needs treating
- When we can work, for business premises
- The size of the job
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

New build mastic in Neilston: local notes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. Neilston is in the west of Scotland, which 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 Neilston station, it’s worth checking the sealant early, while snags are still fresh.

When to call us in Neilston
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
It’s worth asking for a quote if you see:
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
- Internal frame sealant that has split
- Sealant applied over dusty or wet surfaces
Around Neilston, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote

How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots. Outside jobs in Neilston need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. Not sure whether yours can wait? You can send an email to info@mrmastic.co.uk with a few pictures and we’ll give you a straight answer. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why book with us
- Anti-fungal silicone where joints get wet
- More than 20 years in sealant work
- Trusted Arbo and Everbuild sealants
- An ARBOMaster approved applicator

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
