About our new build mastic in Hillswick
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. Common call-outs are for plot mastic for developers ahead of handover and internal frame sealant that has split, on kitchens, show homes and bathrooms & en suites.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.

How the job changes by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
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 before the next move-in.
We also work for property managers and facilities teams in Hillswick and across the Shetland Islands. Several sites can be quoted together, and we are fully insured for the work.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
What affects the cost of new build mastic
Your quote is based on your job. We look at:
- The number of rooms or windows
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- The problem you’ve noticed
- Where the job is, and your postcode
Every job is quoted individually. Just email us at info@mrmastic.co.uk with the details.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Keep children and pets away from the work area

New build mastic in Hillswick: local notes
Hillswick 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. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Whether the job is in Hillswick itself or nearby, the right material for each joint matters as much as a neat finish. Around Hillswick, as everywhere, new build mastic is only as good as the preparation behind it.
Hillswick is in the Shetland Islands. Every kind of property in Hillswick can book us for new build mastic. The work is guaranteed for a year. Across the Shetland Islands, we cover 63 places, Hillswick among them.

Questions from Hillswick
Do you cover smaller places like Hillswick?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Can you do new build mastic in Hillswick?
Yes, Hillswick is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses.
Where is Mr Mastic based?
We work from Crawley. We cover Hillswick and the rest of the Shetland Islands.
How long does new build mastic take?
That depends on the amount of work, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved for a clear quote.
What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
