New build mastic in Aiginis, done properly
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We’re often asked to deal with worktop and upstand sealant coming away and gaps between new skirting and floors, on plot handovers, bathrooms & en suites and kitchens.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Whatever the size of the job, you get the same 12-month guarantee.

What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

Do you need new build mastic in Aiginis?
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Keep an eye out for any of the following:
- Leaking shower tray seals in a new home
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
- Plot mastic for developers ahead of handover
Whether the job is in Aiginis itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before you book
- Is the old sealant removed completely?
- Whether you can choose the colour
- How the surfaces are prepared before sealing
- When the joint can take water or movement
New build mastic in Aiginis: local notes
Aiginis 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.
Around Aiginis, as everywhere, new build mastic is only as good as the preparation behind it.
Aiginis (Gaelic: Aignish) is in Na h-Eileanan Siar. Whether you’re in the middle of Aiginis or further out, new build mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Our area takes in 87 places across Na h-Eileanan Siar.
All of HS2 is covered for new build mastic, from the main roads to the quietest streets. If you are just outside Aiginis, we cover Na h-Eileanan an Iar (1 mile north-east), Knock (1 mile east), Lower Bayble (2 miles east), Garrabost (2 miles north-east) and Pabail Uarach (3 miles east). If you’re somewhere remote, a little more planning is needed, so let us know when you get in touch.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep water off fresh sealant until it has cured
- Ventilate bathrooms well, especially in the first year
- Wipe joints with warm soapy water
- Check bath and shower seals every few months as the house settles
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. 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.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.
