Walls and rooflines in Howden
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Historic houses like Howden House (about 0.2 miles north-east) are a reminder that the area around Howden has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as St. Margaret's Academy, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Livingston North station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Howden is about 1 mile south of Livingston, in West Lothian. Howden gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee.

Local landmarks in Howden
Typical jobs here are in homes near Inveralmond Community High School and The NewYearField pub, among other places. Howden’s nearest station is Livingston North station, roughly 1.2 miles north-west.

How we handle external mastic in Howden
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include rigid filler in a joint that should flex and joints where the bead has come unstuck, across render & cladding joints, joints between brick and frames and brickwork movement joints.
Outside joints can only be sealed when they’re dry, so work in Howden depends on the weather. Let us know about access to every wall and roofline.
A one-year guarantee comes as standard, so you’re covered after we have gone.

What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In a place like Howden, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
- Keep water from gutters off the wall
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Your questions about external mastic in Howden
Do you cover smaller places like Howden?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Livingston North station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Are you fully insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces, primed where needed.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you need external mastic in Howden?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
Homes close to St Andrew's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How it works
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work normally takes anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, 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.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Preparing for the visit
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
