Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
External mastic for homes and businesses in Pumpherston
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. We work on copings & trims, joints between brick and frames and brickwork movement joints, and people most often call us about failed seals between different materials and plants rooting in failed movement joints.
External sealant needs dry surfaces, so outdoor work around Pumpherston is planned around the weather. Let us know about access to every wall and roofline.
You get a 12-month guarantee, the same in Pumpherston as everywhere else we work.

External mastic in Pumpherston: local notes
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. With historic houses such as Howden House (about 1.4 miles south-west) nearby, there’s older building stock in the area around Pumpherston as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Uphall station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to St Andrew's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Pumpherston is about 1 mile north-east of Livingston, in West Lothian.

Local landmarks in Pumpherston
The closest station to Pumpherston is Uphall station, about 0.8 miles north of the centre. A little further out are St John's Hospital (1.6 miles south-west) and The Centre (1.8 miles south-west). Not far away are Dechmont Law.
Why it’s worth doing now in Pumpherston
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Pumpherston, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

Pumpherston: your questions answered
Is Pumpherston within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Pumpherston?
Yes, Pumpherston is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Can new sealant go over the old?
No, and we never do. 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.
How do you reach high-level joints?
Each building is different. Send us pictures and a rough idea of the height and we’ll confirm how they can be reached safely.
Can landlords and businesses book you?
Yes, regularly. Several properties can go on one quote.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- Working hours on commercial sites
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- Whether it has been sealed before
- The address or postcode of the job
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.
When to call us in Pumpherston
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
The problems people usually mention when they call include:
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Plants rooting in failed movement joints
- Leaking joints around cladding and façade panels
For site and facilities teams at buildings such as Inveralmond Community High School, its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- Whether they seal over old material or remove it
- What the quote includes, VAT included or not
