How we handle new build mastic in South Gyle
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 new bead bonds properly instead of bonding to the dust. We work on bathrooms & en suites, kitchens and windows & doors, and the jobs we see most are new-build shower sealant that has already split and skirting joints opening in the first winter.
Offices, shops and commercial units in Scotland’s cities have floors with movement joints and thresholds that take heavy wear. Those joints, and plot mastic for developers, are part of the work we cover in South Gyle.
All our work is covered by our one-year guarantee, wherever you are in Edinburgh.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Your questions about new build mastic in South Gyle
Is new build mastic in South Gyle guaranteed?
All our work, in South Gyle and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover South Gyle for new build mastic?
Yes, South Gyle is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
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.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Damaged fittings that need replacing
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

What the job involves on each surface
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. In a tenement flat in South Gyle, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Why book with us
- Approved under the ARBOMaster scheme
- A sealant colour to suit the surroundings
- Colour agreed with you before work begins
- Every job guaranteed for a year

Joints and finishes in South Gyle homes
South Gyle is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, 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.
Around South Gyle, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near South Gyle station, the sealant around baths, showers and frames is worth checking in the first year or two.
