External Mastic across Midlothian

Our external mastic service in Midlothian

For buildings in Midlothian, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We are often asked to deal with weeds or debris growing in open joints and joints with sealant missing in places, on façade panels, copings & trims and brickwork movement joints.

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation.

  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. Backing rod goes in so the sealant can stretch between the two faces.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Local landmarks in Bonnyrigg

We work in homes and buildings around Bonnyrigg Parish Church, Lasswade High School Centre and Public Library, among other places. Bonnyrigg’s nearest station is Eskbank station, about 1.1 miles north-east of the centre. Well-known places in the area include Dalhousie Castle (1.2 miles south-east) and Midlothian Community Hospital (0.8 miles north-east). Not far away are The New Leaf Co-op and Edgelaw Reservoir.

External mastic across Midlothian: local notes

From Bonnyrigg, Dalkeith and Penicuik to its smaller places, buildings across Midlothian have walls, gutters and rooflines of every age. All of them move, so they need a flexible sealant at the right depth.

The west of Scotland is wetter than the east, but outside joints take plenty of weather everywhere, while generally soft water means less limescale indoors but no less mould. That shapes the choice of sealant for jobs across Midlothian. Parts of Midlothian are on or near the coast, where wind-driven rain and, closer to the shore, salt air are hard on outside sealant. Joints on seaward walls tend to fail first.

Bonnyrigg: For an older house near a landmark such as Bonnyrigg Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Lasswade High School Centre? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How to look after the new joints

Aftercare is simple:

  • Don’t let climbing plants root in the sealant
  • Check the sealant is paintable before painting near it
  • Show decorators and builders where the movement joints are
  • Deal with leaking gutters that soak the joints below

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

Act while the splits are small. At that stage it’s a simple cut out and reseal.

Should I try it myself first?

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, then guaranteed for a year.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Surface by surface

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.

Render joints

Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.

What affects the cost of external mastic

Call for a quick quote. The main things that affect it are:

  • Any working-time requirements on site
  • The product the joint needs
  • Mould in or behind the old joints
  • The old material and how stubborn it is

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What we need to know

To make quoting easier, let us know:

  • Photos by email, if that’s easy
  • The rough size of the job
  • What’s wrong with the joints now
  • Any access issues, like height or stairs

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

When it isn’t the sealant

Before you book, it’s worth knowing the limits:

  • Walls that need new movement joints cut into them
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Movement that’s more than a sealant joint can take

Midlothian: your questions answered

I’m a tenant. Can you help?

We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Can you seal joints between two different materials?

Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.

How long before the joint can be used?

It depends on the product and the conditions. Before we leave, we will tell you the cure time.

How long does the job take?

That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll tell you when we quote.

What sealant do you use?

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

Is the work guaranteed?

Yes. All our work carries our 12-month guarantee.

Do you use backing rod?

We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
