How we handle external mastic in East Calder
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you’re dealing with failed sealant between panels on a façade and sealant pulling away from one side of the joint, we can help, on brickwork movement joints, façade panels and render & cladding joints alike.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.
A 12-month guarantee comes as standard.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Why it’s worth doing now in East Calder
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

What external mastic looks like in East Calder
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.
Rented homes near Kirknewton station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Common problems we fix in East Calder
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
People usually contact us after spotting one of these:
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
Historic houses such as Howden House, about 2.5 miles west, show how far back building around East Calder goes.
Questions to ask before booking
- How much experience the applicator has
- Are they insured?
- How the colour is chosen
- Whether they seal over old material or remove it
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Act on the first splits you see
- Do not let climbing plants root in the sealant
- Tell anyone working on the walls about the movement joints
- Keep movement joints as flexible joints, not mortar
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
How it works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job generally takes a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

Do you take out the old sealant first?

How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.
Can you reach joints on upper floors?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we will confirm what access is needed.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
