External mastic in Kirknewton

Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you have joints pointed up with cement by mistake and rain getting behind render or cladding at a joint, we can help.

Outside joints can only be sealed when they’re dry, so work in Kirknewton depends on the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.

Your job is guaranteed for a year, as with all our work.

Kirknewton buildings and the weather

Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

In the older streets around Kirknewton Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Kirknewton is about 4 miles east of Livingston, in West Lothian. We carry out external mastic for householders, landlords and businesses in Kirknewton.

How the job changes by surface

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

Joints between dissimilar materials

Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Wash walls gently around the sealant
  • Keep movement joints as flexible joints, not mortar
  • Fix overflowing gutters above sealed joints
  • Leave the joints unpainted unless we have said otherwise

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

If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

Signs you need external mastic in Kirknewton

If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.

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

  • Panel joints letting water in
  • Sealant that has lost its bond to the brick or render
  • Damp patches traced to an open external joint
  • Rigid filler in a joint that should flex

For landlords with property near Kirknewton station, split movement joints are easy to miss on a rental until damp shows inside.

10 questions to ask before you book

For landlords and businesses

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. 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 getting the depth right matters as much as the look.

The process

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a place like Kirknewton, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Mention any leaks or damp you’ve noticed
  • Mention if the joints have been sealed before

What we can’t put right

It helps to know what we cannot do too:

  • Cracking across the wall rather than at a joint
  • Structural movement, which needs a surveyor or engineer
  • Cutting new joints into brickwork, which is building work rather than sealant work

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

What we seal

  • Copings & trims
  • Concrete & block
  • Render & cladding joints
  • Façade panels
  • Brickwork movement joints
  • Joints between brick and frames

Yes, Kirknewton 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.

Is Kirknewton within the area you cover?

Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint before resealing.

How long does external mastic last?

It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.

What sealant do you use?

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

Can you seal joints between two different materials?

Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.

Can landlords and businesses book you?

Yes. Domestic, commercial and hotel work are all part of what we do.

How do I get a quote for external mastic in Kirknewton?
