About our new build mastic in Port Bannatyne
We work in new homes and on new-build sites across Port Bannatyne. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you are dealing with joints pulling apart as timber shrinks and sealant applied over dusty or wet surfaces, we can put it right.
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 one-year guarantee in Port Bannatyne and across Argyll and Bute.

Advice
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Port Bannatyne, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Port Bannatyne is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.

Common questions in Port Bannatyne
Do you cover Port Bannatyne for new build mastic?
Yes, Port Bannatyne is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Do you cover smaller places like Port Bannatyne?
Yes. Port Bannatyne is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
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. We use products from Arbo and Everbuild.
Do you work through snagging lists?
Yes. Send it with photos and we will quote for the sealant items. If something isn’t sealant, we’ll say so.
How long should I leave it?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Different surfaces, different methods
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
