New build mastic around Gavinton
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Around Gavinton, as everywhere, new build mastic is only as good as the preparation behind it. For jobs in and around Gavinton, choosing the right material for each joint is as important as a tidy finish.

New build mastic in Gavinton
Across Gavinton, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We are often asked to deal with sealant applied over dusty or wet surfaces and leaking shower tray seals in a new home, across skirting & floors, bathrooms & en suites and show homes.
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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Leave it or put it right?
A hairline gap at a skirting can wait, but water getting through cannot. If you’re unsure which you have, send an email to info@mrmastic.co.uk with pictures. In a place like Gavinton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Your questions about new build mastic in Gavinton
Can you do new build mastic in Gavinton?
Yes. Our work covers the whole of Scotland, and Gavinton is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Do you cover smaller places like Gavinton?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Landlord and commercial work in Gavinton
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
For anyone letting property in or around Gavinton, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Avoid running a DIY bead over the old one
- Use the extractor fan every time you shower
- Act quickly if a seal starts to leak
- Keep photos and emails about snagging items
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Plumbing faults behind the sealant
- Baths and trays that move too much for sealant to cope with
- Broken tiles or a split tray
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.
What we seal

How it works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. Somewhere like Gavinton may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

Advice

Should I try it myself first?
If you are set on DIY, put the effort into 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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
