External mastic in Nethy Bridge

How we handle external mastic in Nethy Bridge

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. Typical jobs include moss and dirt in joints with no sealant left and failed seals between different materials, across copings & trims, concrete & block and façade panels.

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

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?

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

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Keep high-pressure jets off the joints
  • Deal with leaking gutters that soak the joints below
  • Get split or bare joints resealed while the damage is small
  • Keep movement joints as flexible joints, not mortar

Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.

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.

Do you need external mastic in Nethy Bridge?

Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.

Signs it’s time to call us include:

  • Joints with sealant missing in places
  • Movement joints filled with mortar instead of sealant
  • Failed sealant between panels on a façade
  • Old sealant gone brittle and cracked

Homes close to Abernethy Parish Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

10 questions to ask before booking

How the visit works

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building. For a place like Nethy Bridge, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. The old mastic and anything lodged in the joint is removed.
  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. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Mention if the joints have been sealed before
  • Mention any parking rules near the property

Do you cover smaller places like Nethy Bridge?

Yes. Nethy Bridge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.

Yes. Tell us about everything you’d like done and we’ll quote it together.

Do you hold any approvals?

Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Is there a guarantee?

Yes. There’s a 12-month guarantee on every job, large or small.

What sealant do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

When will the joints need doing again?

That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.

What external mastic looks like in Nethy Bridge

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Cracked brickwork or render that needs a builder or plasterer
  • Failed render or damaged cladding panels
  • Damp that isn’t coming from the joint

If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Surfaces we seal

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

Why it’s worth doing now in Nethy Bridge

Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Instead of a standard rate, 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.

Why Nethy Bridge clients choose us
