About our new build mastic in Aithsetter

Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. We work on show homes, bathrooms & en suites and windows & doors, and people most often call us about gaps opening as the house dries out and settles and plot mastic for developers ahead of handover.

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.

Every job is covered by our 12-month guarantee, wherever you are in the Shetland Islands.

Do you need new build mastic in Aithsetter?

Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.

The most common problems we see are:

  • Worktop and upstand sealant coming away
  • Messy sealant that spoils new finishes
  • Second-fix sealing on new plots
  • Cracked sealant around new window and door frames

Around Aithsetter, as everywhere, new build mastic is only as good as the preparation behind it.

Choosing a sealant specialist

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we are fully insured.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Report sealant problems to your builder during the snagging period
  • Check bath and shower seals every few months as the house settles
  • Open a window or run the fan after bathing
  • Photograph failed sealant before it’s redone

Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day to cure enough for use.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

New build mastic in Aithsetter: local notes

Aithsetter 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, so skirting and sealant joints can open up as the building settles.

For jobs in and around Aithsetter, choosing the right material for each joint is as important as a tidy finish.

When it is not the sealant

A few problems are outside what sealant work can do:

  • Your warranty claim itself, which is between you and the builder
  • Structural cracks in walls or ceilings
  • Leaking fittings rather than failed sealant

If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.

What happens on the day

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It generally takes anything from a few hours to several days, depending on the number of plots. Around Aithsetter, distance and access matter more than parking. Let us know how to find you and how to reach the joints.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • On commercial sites, let us know about site rules
  • For indoor joints, keep the area dry beforehand if you can

Aithsetter questions

Do you cover smaller places like Aithsetter?

Yes, Aithsetter is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you do new build mastic in Aithsetter?

Yes, Aithsetter 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, and we’ll give you a clear price.

When is the sealant fully cured?

Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.

Which products do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Where is Mr Mastic based?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Should I wait before resealing?

It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures.

Surface by surface

Show homes

Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.

Plot handovers

Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.

Why it’s worth doing now in Aithsetter

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In an older home around Aithsetter, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

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 make a difference, and we’ll explain the quote if you ask.
