We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We’re often asked to deal with skirting joints opening in the first winter and untidy sealant flagged on a snagging list, across skirting & floors, windows & doors and bathrooms & en suites.
Work in a place like Ballantrae is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.

What we’re called out for in Ballantrae
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
The problems people usually mention when they call are:
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
For jobs in and around Ballantrae, choosing the right material for each joint is as important as a tidy finish.

What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

New build mastic in Ballantrae: local notes
Ballantrae is close to 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. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
Around Ballantrae, as everywhere, new build mastic is only as good as the preparation behind it.

Ballantrae questions
Can you do new build mastic in Ballantrae?
Yes. We work across all of Scotland, and Ballantrae is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
What guarantee comes with new build mastic in Ballantrae?
All our work, in Ballantrae and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What happens on the day
At the end, we look at the finished work together. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. Outdoor work around Ballantrae depends on the weather, as sealant needs a dry surface, 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.
- We cut out every bit of the failed or messy sealant.
- 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.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Also in Ballantrae
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Disputes or warranty claims with your builder
- A tray or bath that is not properly supported, until it’s fixed
- Broken tiles or a split tray
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
