New build mastic in Gullane, done properly
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. If you have skirting joints opening in the first winter and beads laid onto grit and dust from the build, we can help, whatever the surface.
Work in a place like Gullane is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What sealant work can’t fix
In fairness, some problems need a different trade:

- Broken tiles or a split tray

Gullane: your questions answered
Can you help a landlord with a rental near Drem station?
Yes. We work for landlords and agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Can you do new build mastic in Gullane?
Yes, Gullane is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
How the visit works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for most snagging lists, longer for a run of plots. Outside jobs in Gullane need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Mention if the joints have been sealed before

New build mastic in Gullane: local notes
Gullane is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For new homes near Drem station, it’s worth checking the sealant early, while snags are still fresh.

Signs you need new build mastic in Gullane
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
The most common problems we see are:
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
Around Gullane, as everywhere, new build mastic is only as good as the preparation behind it.

Landlord and commercial work in Gullane
If you manage several properties in or around Gullane, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Looking after it afterwards
Looking after new joints is easy:
- Put sealant faults on your snagging list early
- Keep water off fresh sealant until it has cured
- Do not seal over failed sealant yourself
- Keep pictures and emails about snagging items
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
