How we handle external mastic in Lower Bayble

Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on joints between brick and frames, brickwork movement joints and copings & trims, and the jobs we see most are plants rooting in failed movement joints and old sealant gone brittle and cracked.

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

There’s a 12-month guarantee on every job.

Leave it or put it right?

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. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before work begins.

Common questions in Lower Bayble

Do you cover smaller places like Lower Bayble?

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.

Is external mastic in a coastal place like Lower Bayble any different?

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

How do I get a quote for external mastic in Lower Bayble?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Will the new joint stand out?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it does not stand out.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before resealing.

How it works

There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. For a place like Lower Bayble, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.

  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. 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.

Getting ready for the visit

  • Tell us if parking is tricky
  • Clear items away from the joints we’re working on

Related advice

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Common problems we fix in Lower Bayble

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.

Any of these means the joints need attention:

  • Failed seals between different materials
  • Movement joints filled with mortar instead of sealant
  • Movement joints with cracked, split or missing sealant
  • Damp patches traced to an open external joint

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

10 questions to ask before you book

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Walk round the building once a year and look at the joints
  • Keep soil, plants and ivy away from the joints
  • Point out the joints to other trades
  • Have failed joints looked at early

Keep pressure washers away from the sealant. High-pressure water can lift the edges.

Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

How the job changes by surface

Brickwork movement joints

Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly.

Render joints

Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.

Walls and rooflines in Lower Bayble

Lower Bayble is within about 1 mile 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. Island weather, with its wind and salt spray, is tough on movement joints and outside wall joints.

Whether the job is in Lower Bayble itself or nearby, the right material for each joint matters as much as a neat finish.

Honest limits

It helps to know what we can’t do too:

  • Cracked brickwork or render that needs a builder or plasterer
  • Adding movement joints to masonry that has none
  • Structural movement, which needs a surveyor or engineer
