What we do, step by step

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Outdoor work around Netherton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.

  1. First we look over the joints with you, agree which to renew and talk through access.
  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.

How to prepare

  • Let us know about parking restrictions
  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks

How we handle external mastic in Netherton

Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We work on façade panels, brickwork movement joints and concrete & block, and common reasons people get in touch are failed seals between different materials and water getting into walls through failed joints.

Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.

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

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Never let anyone fill a movement joint with mortar
  • Keep high-pressure jets off the joints
  • Get split or bare joints resealed while the damage is small
  • Fix overflowing gutters above sealed joints

Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.

Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

What affects the quote in Netherton

Jobs vary more than people expect. What affects the quote:

  • Any working-time requirements on site
  • The size of the job
  • How easy the joints are to reach
  • Mould in or behind the old joints

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before we start.

What to tell us for a quote

What to tell us when you ask for a quote:

  • If it’s domestic, commercial or a hotel
  • How many joints, rooms or windows are involved
  • The problem you’ve noticed
  • Photos by email, if that is easy

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and give you a clear quote.

Different surfaces, different methods

Joints between dissimilar materials

Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.

Brickwork movement joints

Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.

Why act early in Netherton

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. A stiffer product can damage the joint edge as it fails. In an older home around Netherton, damp from a failed joint can get into timber and plaster.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

What external mastic looks like in Netherton

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. With historic houses such as Cambusnethan House (about 0.9 miles south) nearby, there’s older building stock in the area around Netherton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

In the older streets around St Patrick's R.C. Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Our Lady's High School, larger buildings have long runs of movement joint that eventually need resealing.

Do you need external mastic in Netherton?

Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.

Keep an eye out for any of the following:

  • Joints with sealant missing in places
  • Joints pointed up with cement by mistake
  • Weathered mastic that no longer stretches
  • Sealant that has lost its bond to the brick or render

Rented homes near Shieldmuir station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Honest limits

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

  • Cracked brickwork or render that needs a builder or plasterer
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Structural movement, which needs a surveyor or engineer

Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.
