New build mastic for homes and businesses in Nether Blainslie
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on plot handovers, bathrooms & en suites and windows & doors, and common reasons people get in touch are beads laid onto grit and dust from the build and messy sealant that spoils new finishes.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, email us at info@mrmastic.co.uk with pictures and we will give you a straight answer. In an older home around Nether Blainslie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

How much does new build mastic cost in Nether Blainslie?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
Different surfaces, different methods
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It usually takes anything from a few hours to several days, depending on the number of plots. Outside jobs in Nether Blainslie need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules

Advice
What we are called out for in Nether Blainslie
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
People usually contact us when they notice something like this:
- Plot mastic for developers ahead of handover
- Cracked caulk along new skirting
- Sealant that never bonded to the surface
- Frame joints opening as the plaster dries
For jobs in and around Nether Blainslie, choosing the right material for each joint is as important as a tidy finish.
