Surface by surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
New build mastic in Nerston, done properly
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. If you have frame joints opening as the plaster dries and new-build shower sealant that has already split, we can put it right, whatever the surface.
Work in a place like Nerston is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Whatever the size of the job, you get the same one-year guarantee in Nerston and across South Lanarkshire.

Your questions about new build mastic in Nerston
I let a flat near East Kilbride station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Will you come out to Nerston?
Yes, Nerston is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How do I get a quote for new build mastic in Nerston?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Is the work guaranteed?
Yes. All our work carries our one-year guarantee.
Who should fix failed sealant in a new build?
Report it to the builder first while you are covered. Once that’s done, or if they won’t put it right, we’ll cut it out and reseal it.

Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. 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.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
New build mastic in Nerston: local notes
Nerston is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near East Kilbride station, it’s worth checking the sealant early, while snags are still fresh. Around Nerston, as everywhere, new build mastic is only as good as the preparation behind it.

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 job generally takes anything from a few hours to several days, depending on the number of plots from start to finish. Outdoor work around Nerston depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
