How we handle new build mastic in Port Appin
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on show homes, windows & doors and plot handovers, and common reasons people get in touch are plot mastic for developers ahead of handover and shower seals failing in the first year or two.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Every job comes with a 12-month guarantee.

Looking after it afterwards
To keep the joints looking good and working properly:
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
- Act quickly if a seal starts to leak
- Keep pictures and emails about snagging items
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
Signs you need new build mastic in Port Appin
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.

What else we do in Port Appin
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

- Windows & doors
- Show homes
- Skirting & floors
- Plot handovers
Surface by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors as agreed.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
New build mastic around Port Appin
Port Appin is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For jobs in and around Port Appin, choosing the right material for each joint is as important as a tidy finish.
