New build mastic in Pathhead, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. If you are dealing with joints pulling apart as timber shrinks and second-fix sealing on new plots, we can put it right, on plot handovers, show homes and skirting & floors alike.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

Leave it or put it right?
The builder is generally the first port of call while the snagging or warranty period runs. 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 Pathhead, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

How we quote for new build mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- The amount of work
- How easy the joints are to reach
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The rough size of the job
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height

What new build mastic looks like in Pathhead
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around Pathhead, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Gorebridge station, it’s worth checking the sealant early, while snags are still fresh.

- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated pictures
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered.

Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How much does new build mastic cost in Pathhead?

Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Should I try DIY first?
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.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
