About our external mastic in Whitecraig
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on copings & trims, joints between brick and frames and concrete & block, and common reasons people get in touch are cracked joints where brick meets render or frames and movement joints with cracked, split or missing sealant.
In and around a place like Whitecraig, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Whitecraig questions
Can you help a landlord with a rental near Wallyford station?
Yes. We work for landlords and agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Is Whitecraig within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall. If it has already been filled, we can normally cut it out and reseal it.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
Can you seal joints between render and window frames?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- The amount of work
- Access and height
- Any mould that needs treating
- The number of rooms or windows
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- A few photos by email, if you can
- The rough size of the job
- Access, such as stairs, a lift or height
- Whether it has been sealed before
If you are in Whitecraig and need external mastic, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.
Surfaces we seal
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Concrete & block
- Copings & trims
Common problems we fix in Whitecraig
Some movement joints have been pointed up with mortar. The joint can’t move, so the wall cracks somewhere else instead.
The problems people generally mention when they call include:
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Movement joints filled with mortar instead of sealant
- Cracked joints where brick meets render or frames
Rented homes near Wallyford station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. For a place like Whitecraig, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Related advice
Why it’s worth doing now in Whitecraig
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Whitecraig, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Different surfaces, different methods
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
External mastic in Whitecraig: local notes
Whitecraig is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Loretto School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Hamilton House, about 3.3 miles north-east, is one of the historic houses in the wider area around Whitecraig.
