About our external mastic in Donside Village

External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on copings & trims, joints between brick and frames and render & cladding joints, and common reasons people get in touch are failed seals between different materials and joints pointed up with cement by mistake.

Stone-built tenements in Scotland’s cities share their roof, gutters and outside walls between every flat in the building. In Donside Village, work on shared parts of a tenement is usually agreed between owners, often with a factor arranging it.

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

What happens if it’s left?

Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Donside Village, damp can travel a long way before it shows.

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

How the job changes by surface

Joints between dissimilar materials

Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so the movement is taken up.

Copings and trims

Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.

Walls and rooflines in Donside Village

Donside Village is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.

For landlords with property near Aberdeen station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around St Joseph's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Tell anyone working on the walls about the movement joints
  • Keep water from gutters off the wall
  • Look over the joints every year, ideally after winter
  • Get split or bare joints resealed while the damage is small

Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.

Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

When to call us in Donside Village

Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.

People normally contact us after spotting one of these:

  • Failed sealant between panels on a façade
  • Movement joints filled with mortar instead of sealant
  • Hard, crazed mastic that has stopped moving
  • Weeds or debris growing in open joints

Managing a site like St Machar Academy? Then larger buildings have long runs of movement joint that eventually need resealing.

Before you book anyone

  • Whether the sealant suits the joint
  • Is the old sealant removed completely?
  • When the joint can take water or movement
  • Who turns up on the day

How to choose a mastic man

What we do, step by step

The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes a few hours to a few days, depending on the length of joint and the access. Parking in city streets around Donside Village can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.

  1. We look at every joint and agree a colour to suit the wall.
  2. Failed sealant is removed back to clean, sound faces.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

Getting ready for the visit

Advice

What we can’t put right

New sealant cannot fix everything, and we’ll tell you before work begins. It will not solve:

  • Failed render or damaged cladding panels
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Movement that is more than a sealant joint can take

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

Joints and surfaces we work on

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

How we quote for external mastic

The price is agreed before any work begins. It takes into account:

  • Whether there’s mould to deal with
  • Which sealant suits the joint
  • The number of rooms or windows
  • How much there is to do

Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What to tell us for a quote

To make quoting easier, please include:

  • The type of property
  • How we’d reach the joints
  • If someone has resealed it before
  • Where the property is

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Donside Village questions

I let a flat near Aberdeen station. Can you help?

Yes. We work for landlords and agents as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.

Who arranges sealant work on the shared parts of a tenement in Donside Village?

Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Do you work in Donside Village?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Donside Village included.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

Can a movement joint be filled with mortar?

No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
