New build mastic for homes and businesses in Blackhills
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Common call-outs are for gaps behind new kitchen upstands and leaking shower tray seals in a new home, on show homes, bathrooms & en suites and windows & doors.
Around smaller Scottish places like Blackhills, 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.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
FAQs for Blackhills
Do you cover smaller places like Blackhills?
Yes. Blackhills is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Elgin station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
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 we start.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we will ask.
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can email us at info@mrmastic.co.uk with a few pictures. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Signs you need new build mastic in Blackhills
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
If you can see any of these, it’s time to have the joints looked at:
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
For new homes near Elgin station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- How long to leave it before use
- What happens if the job turns out different
- Are they insured?
- Which colour the sealant will be
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
