New build mastic in Unthank

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Report sealant problems to your builder during the snagging period
  • Ventilate bathrooms well, especially in the first year
  • Follow the cure time we give you
  • Resist patching a failed seal with a tube from the DIY shop

Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.

A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

New build mastic for homes and businesses in Unthank

Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on show homes, plot handovers and skirting & floors, and the jobs we see most are gaps between new skirting and floors and joints pulling apart as timber shrinks.

Work in a place like Unthank is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.

All our work comes with our 12-month guarantee, wherever you are in Angus.

What we do, step by step

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for most snagging lists, longer for a run of plots. For a place like Unthank, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely.
  3. Joints are vacuumed and cleaned of building dust.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • Keep pets and children clear of the area while we work
  • Clear items away from the joints we’re working on

What we are called out for in Unthank

On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.

Common reasons people contact us are:

  • New-build shower sealant that has already split
  • Frame joints opening as the plaster dries
  • Untidy sealant flagged on a snagging list
  • Worktop and upstand sealant coming away

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

Unthank: your questions answered

Is Unthank in your area for new build mastic?

Yes, Unthank is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.

Is new build mastic in Unthank guaranteed?

All our work, in Unthank and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.

Can landlords and businesses book you?

Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply drop us a line at info@mrmastic.co.uk.

My new home is still under warranty. Should I contact you?

Report it to the builder first while you’re covered. If it isn’t resolved, we can reseal it properly.

What colour sealant will you use?

White and clear are the most common, but other colours are available. We choose one to suit the room before we begin.

Why has my new-build shower seal failed already?

Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.

Leave it or put it right?

A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • Colour agreed with you before any work starts
  • Anti-fungal silicone where joints get wet
  • White, clear, grey or another colour, product permitting
  • Tidy, careful work

Read our cost guide or what customers say.

What we cannot put right

Some problems need a builder, plumber or other trade rather than us:

  • Settlement cracks that need a surveyor
  • A tray or bath that is not properly supported, until it’s fixed
  • Your warranty claim itself, which is between you and the builder

If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
