How we handle external mastic in Stamperland

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. We work on copings & trims, concrete & block and façade panels, and people most often call us about damp patches traced to an open external joint and movement joints with cracked, split or missing sealant.

Alongside their tenements, Scotland’s cities have modern blocks with render, cladding and movement joints. Around Stamperland, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.

Our work is backed for twelve months, in Stamperland and everywhere else we cover.

Leave it or put it right?

Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In a tenement flat in Stamperland, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Common problems we fix in Stamperland

Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint cannot move, so the wall cracks somewhere else instead.

Common reasons people contact us include:

  • Rigid filler in a joint that should flex
  • Weathered mastic that no longer stretches
  • Sealant pulling away from one side of the joint
  • Gaps where render, brick and frames meet

For an older house near a landmark such as Williamwood Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Questions to ask before you book

  • What product goes in the joint
  • How hidden problems are handled
  • When the joint can take water or movement
  • What the quote includes, VAT included or not

How to choose a mastic man

What happens on the day

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. Inside a flat in Stamperland, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  3. The faces are brushed clean and primed where the product requires it.
  4. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

Before we arrive

  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive
  • For business premises, tell us about site rules or sign-in

What affects the cost of external mastic

The price is agreed before any work begins. It takes into account:

  • Whether there’s mould to deal with
  • The size of the job
  • The number of rooms or windows
  • The product the joint needs

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before work begins.

You do not need to know the technical terms. Just tell us:

  • Whether it has been sealed before
  • The rough size of the job
  • Where the job is, and your postcode
  • Whether it’s a home or a business

Can you do external mastic in Stamperland?

Yes. Our work covers the whole of Scotland, and Stamperland is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.

Who arranges sealant work on the shared parts of a tenement in Stamperland?

It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.

I’m a tenant. Can you help?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Where are you based?

Our base is in Crawley, and we work across South East England, London and Scotland.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

How long does external mastic last?

There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.

Do you have insurance?

Yes. We are fully insured, and we can confirm the details when we quote.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

External mastic in Stamperland: local notes

The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Your title deeds say which parts are shared. Glasgow’s tenements are largely red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.

If you let a flat or house near Clarkston station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as St Margaret Mary's Secondary School, larger buildings have long runs of movement joint that eventually need resealing.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We cut it out and start again.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

For landlords and businesses

We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Leave the joints unpainted unless we’ve said otherwise
  • Act on the first splits you see
  • Keep movement joints as flexible joints, not mortar
  • Fix overflowing gutters above sealed joints

Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.

Act while the splits are small. At that stage it’s a simple cut out and reseal.
