New build mastic in Nethercraigs
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, plot handovers and kitchens, and people most often call us about beads laid onto grit and dust from the build and frame joints opening as the plaster dries.
New flats and houses are still being built in and around Scotland’s cities, and in new homes, sealant and floor joints are often among the first snags, in Nethercraigs as anywhere.
There’s a 12-month guarantee on every job, large or small.

New build mastic in Nethercraigs: local notes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
If you’ve bought a new home near Corkerhill station, the sealant around baths, showers and frames is worth checking in the first year or two.

What else we do in Nethercraigs
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Leaks from pipes, valves or wastes, which need a plumber
- Deciding who is responsible under a builder’s warranty
- Settlement cracks that need a surveyor
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Skirting & floors
- Bathrooms & en suites
- Show homes
- Windows & doors
- Plot handovers
- Kitchens
Looking after it afterwards
So the new joints stay in good condition:
- Do not seal over failed sealant yourself
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
Landlords, agents and businesses in Nethercraigs
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Common questions in Nethercraigs
Do you cover Nethercraigs for new build mastic?
Yes, Nethercraigs is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
What guarantee comes with new build mastic in Nethercraigs?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you work through snagging lists?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish before we begin.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule. Get in touch with the number of plots and the scope and we will quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Scottish rain finds any gap around a frame or wall joint, and in Nethercraigs, damp can spread through stone and plaster before anyone sees it.
Doing several joints on one visit generally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

How the visit works
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Nethercraigs, tell us the floor, how the door entry system works and where we can park nearby.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
