New build mastic in Laggan, done properly

We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, kitchens and show homes, and common reasons people get in touch are beads laid onto grit and dust from the build and second-fix sealing on new plots.

For a place like Laggan, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.

A one-year guarantee comes as standard.

What happens on the day

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours in a single home. Somewhere like Laggan may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. First we work through your snagging list or plot schedule with you.
  2. We cut out every bit of the failed or messy sealant.
  3. Surfaces are cleaned of building dust and primed where needed.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Each area is checked and left with its cure time.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Tell us about any water getting in
  • Clear the area around the work

When something else is needed

Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:

  • Cracking that points to a structural problem
  • Leaking fittings rather than failed sealant
  • Your warranty claim itself, which is between you and the builder

Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.

Surfaces we seal

  • Plot handovers
  • Skirting & floors
  • Windows & doors
  • Kitchens
  • Bathrooms & en suites
  • Show homes

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Why act early in Laggan

Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

When to call us in Laggan

A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.

If you can see any of these, it’s time to have the joints looked at:

  • Kitchen sealant that has pulled off the wall
  • Cracks appearing as a new home settles
  • Frame joints opening as the plaster dries
  • Plot mastic for developers ahead of handover

In and around Laggan, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What your quote should include

  • What happens if the job turns out different
  • Whether VAT is included
  • Who does the work, and how experienced they are
  • What insurance they hold

10 questions to ask before booking

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Wipe joints with warm soapy water
  • Put sealant faults on your snagging list early
  • Follow the cure time we give you
  • Avoid running a DIY bead over the old one

Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.

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

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

New build mastic around Laggan

Laggan is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.

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