Carnoustie New Build Mastic
We cover Carnoustie for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
- Frame joints opening as the plaster dries
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
New build mastic for homes and businesses in Carnoustie
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you have new-build shower sealant that has already split and sealant work across a run of new homes, we can put it right, on windows & doors, show homes and kitchens alike.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Your questions about new build mastic in Carnoustie
I let a flat near Golf Street station. Can you help?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Is Carnoustie within the area you cover?
Yes. Carnoustie is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is the work guaranteed?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Should I wait before resealing?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep water off fresh sealant until it has cured
- Don’t seal over failed sealant yourself
- Wipe joints with warm soapy water
- Get a leaking seal dealt with right away
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
When to call us in Carnoustie
Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry first.
Look out for these signs:
- Cracks appearing as a new home settles
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
For new homes near Golf Street station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Is the old sealant removed completely?
- What happens if they find a problem under the old sealant
- Whether you can choose the colour
- When the joint can take water or movement
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Around Carnoustie, water from a failed joint in an older stone home can soak into timber and plaster.
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.

Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
