New-build mastic & snagging in Greycrook, Scottish Borders

- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out 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, then guaranteed for a year.
New build mastic in Greycrook, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. We’re often asked to deal with joints pulling apart as timber shrinks and internal frame sealant that has split, on kitchens, show homes and plot handovers.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A one-year guarantee comes as standard, so you are covered after we have gone.

Quotes for new build mastic in Greycrook
You will get a clear quote before any work starts. It takes into account:
- How many rooms, windows or areas are involved

- Whether the work is at height
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- Where the property is
- How we’d reach the joints
- The type of property
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, send an email to info@mrmastic.co.uk.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
- Keep photos and emails about snagging items
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
Questions from Greycrook
Will you come out to Greycrook?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is new build mastic in Greycrook guaranteed?
All our work, in Greycrook and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is it normal for sealant to crack in a new home?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Should I wait before resealing?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Why it’s worth doing now in Greycrook
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In an older home around Greycrook, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why Greycrook clients choose us
- Any old sealant cut out fully, not covered over

Common problems we fix in Greycrook
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
The problems people normally mention when they call are:
- Gaps opening as the house dries out and settles
- Cracked sealant around new window and door frames
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
In and around Greycrook, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. 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. Outside jobs in Greycrook need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
How to get a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job.

When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Cracked trays, tiles or worktops
- A tray or bath that is not properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
