About our new build mastic in Askomill
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on show homes, bathrooms & en suites and skirting & floors, and people most often call us about joints pulling apart as timber shrinks and plot mastic for developers ahead of handover.
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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When to call us in Askomill
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Keep an eye out for these signs:
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
Around Askomill, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- Are they insured?
- How long to leave it before use
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Don’t wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

Common questions in Askomill
Do you cover Askomill for new build mastic?
Yes. Our work covers the whole of Scotland, and Askomill is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Is there a guarantee on new build mastic in Askomill?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you’re covered. If it isn’t resolved, we can reseal it properly.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
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.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Broken tiles or a split tray
- Leaking fittings rather than failed sealant
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.

New build mastic in Askomill: local notes
Askomill is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, 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.
Whether the job is in Askomill itself or nearby, the right material for each joint matters as much as a neat finish.
