New-build mastic & snagging in Melby, Shetland Islands
We cover Melby for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

- Gaps opening as the house dries out and settles
New build mastic in Melby
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We are often asked to deal with kitchen sealant that has pulled off the wall and beads laid onto grit and dust from the build, across skirting & floors, plot handovers and show homes.
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.
You get a one-year guarantee, the same in Melby as everywhere else we work.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Watch for new gaps as the house dries out
- Put sealant faults on your snagging list early
- Wait for the cure time before using a resealed shower
- Clean sealant with mild detergent, not abrasives
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

Let us know how to find you and how to reach the joints.

- The failed sealant is removed completely, with no layer left behind.

Advice
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 Melby, water from a failed joint in an older stone home can soak into timber and plaster.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Questions from Melby
Is Melby in your area for new build mastic?
Yes. Our work covers the whole of Scotland, and Melby is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is new build mastic in Melby guaranteed?
All our work, in Melby and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
How long does new build mastic take?
Most jobs take a few hours in a single home, including the preparation. We’ll confirm how long when we quote.
Is there any odour?
Possibly a little. It fades as the sealant cures.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Settlement cracks that need a surveyor
- Broken tiles or a split tray
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

What the job involves on each surface
Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered as agreed.

Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Access and height
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.

- Where the job is, and your postcode
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- The type of property
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we will take it from there.
Joints and finishes in Melby homes
Melby 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
Whether the job is in Melby itself or nearby, the right material for each joint matters as much as a neat finish. Around Melby, as everywhere, new build mastic is only as good as the preparation behind it.
