External mastic in Carsie, done properly

Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on copings & trims, façade panels and render & cladding joints, and the jobs we see most are brick movement joints where the sealant has split and sealant that has lost its bond to the brick or render.

External sealant needs dry surfaces, so outdoor work around Carsie is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Carsie buildings and the weather

Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

Around Carsie, as everywhere, external mastic is only as good as the preparation behind it.

What we do, step by step

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. Somewhere like Carsie may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  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. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Advice

Quotes for external mastic in Carsie

There’s no set price list. The quote depends on:

  • The old material and how stubborn it is
  • Mould in or behind the old joints
  • The type of sealant required
  • When we can work, for business premises

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

What we need to know

There’s no need for technical detail. Just tell us:

  • Roughly how big the job is
  • Access, such as stairs, a lift or height
  • The type of property
  • If someone has resealed it before

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved.

Why act early in Carsie

Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. 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.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Why Carsie clients choose us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • ARBOMaster approved applicator
  • A sealant colour to suit the surroundings
  • Colour agreed with you before work begins

Carsie questions

Is there a guarantee on external mastic in Carsie?

All our work, in Carsie and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Do you cover smaller places like Carsie?

Yes, Carsie is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do you work for letting agents?

Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.

How long does external mastic take?

That depends on how much there is to do, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We will give you a better idea when we quote.

Will it make a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator.

What should I tell you?

Only a few details: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.

Do you need external mastic in Carsie?

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.

If you can see any of these, it’s time to have the joints looked at:

  • Rain getting behind render or cladding at a joint
  • Joints pointed up with cement by mistake
  • Movement joints with cracked, split or missing sealant
  • Weathered mastic that no longer stretches

If you look after a building such as Blairgowrie High School, larger buildings have long runs of movement joint that eventually need resealing.

Before you book anyone

  • How the colour is chosen
  • When the joint can take water or movement
  • Who does the work, and how experienced they are
  • What product goes in the joint

Choosing a sealant specialist

Can I do it myself?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

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 sealant work can’t fix

In fairness, there are a few things sealant won’t fix:

  • Cracked brickwork or render that needs a builder or plasterer
  • Loose or hollow render, which needs re-rendering
  • Cutting new joints into brickwork, which is building work rather than sealant work

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