New build mastic in Sandhead, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on kitchens, windows & doors and skirting & floors, and people most often call us about untidy sealant flagged on a snagging list and skirting joints opening in the first winter.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Signs you need new build mastic in Sandhead
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry before the sealant goes on.
People usually contact us after spotting one of these:
- Frame joints opening as the plaster dries
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
- New-build shower sealant that has already split
For jobs in and around Sandhead, choosing the right material for each joint is as important as a tidy finish.
Before booking anyone
- When the joint can take water or movement
- Who does the work, and how experienced they are
- What insurance they hold
- How hidden problems are handled
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A tray or bath that is not properly supported, until it’s fixed
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.

What happens on the day
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours in a single home. For a place like Sandhead, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

Advice
How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

New build mastic around Sandhead
Sandhead is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
Around Sandhead, as everywhere, new build mastic is only as good as the preparation behind it.
