How we handle new build mastic in Sanquhar
We work in new homes and on new-build sites across Sanquhar. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. Typical jobs include sealant that never bonded to the surface and gaps opening as the house dries out and settles, across windows & doors, plot handovers and bathrooms & en suites.
Around smaller Scottish places like Sanquhar, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.

What new build mastic looks like in Sanquhar
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Sanquhar station, the sealant around baths, showers and frames is worth checking in the first year or two.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours in a single home. Outside jobs in Sanquhar 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. Work indoors is not affected.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks

Advice
Common problems we fix in Sanquhar
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
Around Sanquhar, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- Whether all the old sealant comes out first
- What insurance they hold
- When the joint can take water or movement
- Which sealant they’ll use, and why
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Why act early in Sanquhar
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In an older home around Sanquhar, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What you pay reflects the work, not guesswork. That is why we ask a few questions first.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Windows & doors
- Kitchens
- Bathrooms & en suites
- Plot handovers
- Skirting & floors
- Show homes
Surface by surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.

Yes, Sanquhar is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.

Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Is it normal for sealant to crack in a new home?
It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.
