Trusted new build mastic in Kentallen

New build mastic in Kentallen, done properly

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you are dealing with joints pulling apart as timber shrinks and messy sealant that spoils new finishes, we can put it right, whatever the surface.

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

Our work is backed for twelve months.

Common problems we fix in Kentallen

Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.

Common reasons people contact us include:

  • Kitchen sealant that has pulled off the wall
  • New-build shower sealant that has already split
  • Second-fix sealing on new plots
  • Untidy sealant flagged on a snagging list

Whether the job is in Kentallen itself or nearby, the right material for each joint matters as much as a neat finish.

How to choose a mastic man

How the visit works

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. Outside jobs in Kentallen need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  1. First we work through your snagging list or plot schedule with you.
  2. Failed or untidy sealant is cut out completely.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. We check every joint and tell you how long each needs to cure.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive
  • Plan for the work area to be out of bounds to pets and children

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

How the job changes by surface

Show homes

We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.

Plot handovers

We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing so the sealant lasts.

Looking after it afterwards

After the cure time, these simple habits help:

  • Follow the cure time we give you
  • Check bath and shower seals every few months as the house settles
  • Open a window or run the fan after bathing
  • Resist patching a failed seal with a tube from the DIY shop

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.

What we can’t put right

In fairness, some problems need a different trade:

  • Cracked trays, tiles or worktops
  • Disputes or warranty claims with your builder
  • Structural cracks in walls or ceilings

If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

What we seal

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

Leave it or put it right?

It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. 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.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Why us?

  • Arbo and Everbuild products
  • ARBOMaster approved applicator
  • Colour picked to suit the job
  • You choose the colour before work begins

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

New build mastic around Kentallen

Kentallen is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Kentallen 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.

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