Trusted new build mastic in Netherton

New build mastic in Netherton, done properly

New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for skirting joints opening in the first winter and joints pulling apart as timber shrinks, across kitchens, skirting & floors and windows & doors.

Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.

We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

For landlords and businesses

We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

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

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

The process

We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours in a single home. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.

  1. First we work through your snagging list or plot schedule with you.
  2. The old bead comes out in full, with no layer left behind.
  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.

Before we arrive

  • Let us know about earlier repairs to the joints
  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work

What sealant work cannot fix

Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:

  • Deciding who is responsible under a builder’s warranty
  • A tray or bath that is not properly supported, until it’s fixed
  • Damaged fittings that need replacing

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

Netherton: your questions answered

I let a flat near Shieldmuir station. Can you help?

Yes. We work for letting agents and landlords as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.

Do you cover Netherton for new build mastic?

Yes. We work across all of Scotland, and Netherton is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

How long does the job take?

It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.

Can I add another job to the visit?

Yes. Several rooms, windows or areas can go on one quote.

When is the best time to reseal in a new build?

For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.

Do you take out the old sealant first?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Do you work for developers?

Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.

Looking after it afterwards

A little care helps the new joints last. Our advice:

  • Open a window or run the fan after bathing
  • Check bath and shower seals every few months as the house settles
  • Follow the cure time we give you
  • Wipe joints with warm soapy water

Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.

Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.

When to call us in Netherton

When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.

Signs it’s time to call us include:

  • Shower seals failing in the first year or two
  • Skirting joints opening in the first winter
  • Sealant applied over dusty or wet surfaces
  • Cracked sealant around new window and door frames

If you’ve bought a new home near Shieldmuir station, the sealant around baths, showers and frames is worth checking in the first year or two.

What your quote should include

  • Who turns up on the day
  • The length of the guarantee
  • How the surfaces are prepared before sealing
  • Whether they’re fully insured
