External & façade joints in Dedridge, West Lothian
External mastic across Dedridge and nearby, with old sealant always removed completely.
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In an older home around Dedridge, damp from a failed joint can get into timber and plaster.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

External mastic for homes and businesses in Dedridge
Short cuts in external joints show up within a season or two. 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 brickwork movement joints, joints between brick and frames and render & cladding joints, and the jobs we see most are sealant pulling away from one side of the joint and failed seals between different materials.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
There’s a 12-month guarantee on every job, whatever its size.

External mastic in Dedridge: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Letting a property close to Livingston South station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as St. Margaret's Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Livingston Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Get split or bare joints resealed while the damage is small
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Do not let climbing plants root in the sealant
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly where it can be done safely.
How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Around Dedridge, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
