- Sealant that never bonded to the surface
New build mastic for homes and businesses in Grindiscol
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. If you are dealing with cracks appearing as a new home settles and smeared, uneven beads picked up at snagging, we can put it right, on kitchens, bathrooms & en suites and skirting & floors alike.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

What affects the cost of new build mastic
There’s no set price list. The quote depends on:
- Any mould that needs treating
- Which sealant suits the joint
- The old material and how stubborn it is
- The number of rooms or windows
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
What we are called out for in Grindiscol
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry.
People normally contact us when they notice one of these:
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
- Leaking shower tray seals in a new home
- Gaps opening as the house dries out and settles
Whether the job is in Grindiscol itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
- Is VAT in the price?
How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What new build mastic looks like in Grindiscol
Grindiscol is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
In and around Grindiscol, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Grindiscol is in the Shetland Islands. Our applicators cover new build mastic for homeowners, landlords and businesses in Grindiscol and nearby. Grindiscol is one of 63 towns and villages in the Shetland Islands we cover for new build mastic.

How to look after the new joints
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Raise failed sealant with the developer while you are covered
- Record problems with dated pictures
- Wipe joints with warm soapy water
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

Why act early in Grindiscol
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In an older home around Grindiscol, damp from a failed joint can get 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, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
