How we handle new build mastic in New Trows
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We are often asked to deal with frame joints opening as the plaster dries and sealant applied over dusty or wet surfaces, across plot handovers, bathrooms & en suites and skirting & floors.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

When to call us in New Trows

Common reasons people contact us are:
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
In and around New Trows, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What else we do in New Trows
How the job changes by surface
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that 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 New Trows need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Preparing for the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
When it isn’t the sealant
We won’t take on work that won’t last, so these are the limits:
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
What we seal
- Skirting & floors

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ventilate bathrooms well, especially in the first year
- Photograph failed sealant before it’s redone
- Raise failed sealant with the developer while you are covered
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
