What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. Outside jobs in Kingsmuir 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 is not affected.
- 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.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any tricky access
- On commercial sites, let us know about site rules

New build mastic in Kingsmuir
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We’re often asked to deal with kitchen sealant that has pulled off the wall and second-fix sealing on new plots, on skirting & floors, show homes and kitchens.
Work in a place like Kingsmuir is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Each job carries a 12-month guarantee.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
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.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
Common questions in Kingsmuir
What guarantee comes with new build mastic in Kingsmuir?
All our work, in Kingsmuir and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover Kingsmuir for new build mastic?
Yes, Kingsmuir is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. If that does not work out, we’re happy to quote and our work is guaranteed for a year.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.
Is it worth trying it myself?
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.
What we can’t put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
What we seal

- Kitchens
- Plot handovers

What new build mastic looks like in Kingsmuir

Signs you need new build mastic in Kingsmuir
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry first.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
In and around Kingsmuir, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
