How we handle new build mastic in Arniston
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. We work on bathrooms & en suites, show homes and skirting & floors, and people most often call us about messy sealant that spoils new finishes and skirting joints opening in the first winter.
Work in a place like Arniston is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
There’s a 12-month guarantee on every job, large or small.

New homes and floors in Arniston
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Gorebridge station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Arniston, as everywhere, new build mastic is only as good as the preparation behind it.

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Around Arniston, water from a failed joint in an older stone home can soak into timber and plaster.
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.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Your questions about new build mastic in Arniston
Do you cover Arniston for new build mastic?
Yes, Arniston is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Is Arniston within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
How long does new build mastic take?
Most jobs take anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. We’ll confirm how long when we quote.
Is the work guaranteed?
Yes. Every job comes with a one-year guarantee.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Looking after it afterwards
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

What affects the cost of new build mastic
For a quick quote, just ask. The main things that affect it are:
- The old material and how stubborn it is
- How many areas need sealing
- Which sealant suits the joint
- Whether the work is at height
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
What the job involves on each surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Plot handovers
Send us the schedule and any sealant specification for a quote. We seal bathrooms, kitchens, frames and floors.
How it works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. Outdoor work around Arniston depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
