External mastic in Liquo

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Avoid pressure-washing directly into sealant joints
  • Point out the joints to other trades
  • Deal with leaking gutters that soak the joints below
  • Check the sealant is paintable before painting near it

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.

Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

About our external mastic in Liquo

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on brickwork movement joints, render & cladding joints and façade panels, and common reasons people get in touch are leaking joints around cladding and façade panels and gaps where render, brick and frames meet.

Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?

Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In an older home around Liquo, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How the job changes by surface

Brickwork movement joints

Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

Copings and trims

Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.

Liquo buildings and the weather

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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.

Around Liquo, as everywhere, external mastic is only as good as the preparation behind it. Letting a property close to Hartwood station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

What happens on the day

Our applicators work methodically: 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. Around Liquo, distance and access matter more than parking. Tell us how to find the property and how to reach the work.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. Old sealant and any debris are cut and raked out.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • Clear the area around the work
  • Let us know about parking restrictions
  • Keep children and pets away from the work area

What affects the quote in Liquo

Jobs vary more than people expect. The main factors:

  • Any mould that needs treating
  • The old material and how stubborn it is
  • How many areas need sealing
  • Any working-time requirements on site

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.

What we need to know

When you call or email, these details help:

  • Where the property is
  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved
  • Whether it has been sealed before

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Walls that need new movement joints cut into them
  • Subsidence or other structural problems
  • Failed render or damaged cladding panels

If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.

Joints and surfaces we work on

  • Façade panels
  • Copings & trims
