What sealant work cannot fix

We’d rather tell you now than do work that will not last, so these are the limits:

  • Render that’s blown, hollow or coming away
  • Rising or penetrating damp from elsewhere in the wall
  • 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
  • Joints between brick and frames
  • Render & cladding joints
  • Concrete & block
  • Façade panels
  • Brickwork movement joints

External mastic in Buchlyvie

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 copings & trims, brickwork movement joints and concrete & block, and people most often call us about leaking joints around cladding and façade panels and rigid filler in a joint that should flex.

External sealant needs dry surfaces, so outdoor work around Buchlyvie is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.

Each job carries a 12-month guarantee, whatever its size.

Common problems we fix in Buchlyvie

The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.

Any of these means the joints need attention:

  • Failed seals between different materials
  • Old sealant gone brittle and cracked
  • Joints with sealant missing in places
  • Joints pointed up with cement by mistake

In and around Buchlyvie, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Aftercare tips

After the cure time, these simple habits help:

  • Keep water from gutters off the wall
  • Make sure movement joints aren’t pointed over
  • Keep soil, plants and ivy away from the joints
  • Keep high-pressure jets off the joints

Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

Outside joints around Buchlyvie

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.

For an older house near a landmark such as North Church and Churchyard, an extension built onto an older house moves differently, and the joint between them takes the strain.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What happens if it’s left?

A failed movement joint lets water into the wall and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Exposed walls in smaller Scottish places take a lot of wind and rain, 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: the amount of work, the old material and the access. You’ll know the price before we begin.

What you get with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • Tidy, careful work
  • An ARBOMaster approved applicator
  • White, clear, grey or coloured to suit, where the product allows

What happens on the day

On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Outside jobs in Buchlyvie need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.

  1. First, the joints are inspected and the access agreed.
  2. Every bit of old sealant and any mortar or debris is cut out.
  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. The exterior sealant is applied, tooled and checked along its length.

Before we arrive

  • Clear items away from the joints we are working on
  • Let us know about stairs, lifts or work at height
  • Try not to wet indoor joints just before the visit
