- Rising or penetrating damp from elsewhere in the wall

External mastic in Avongrove
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you are dealing with brick movement joints where the sealant has split and gaps where render, brick and frames meet, we can put it right.
External sealant needs dry surfaces, so outdoor work around Avongrove is planned around the weather, and longer journeys are planned in advance. Tell us how to reach each wall, gutter and roofline.
You get a one-year guarantee, the same in Avongrove as everywhere else we work.

FAQs for Avongrove
Do you work for landlords with property near Hamilton Central station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Can you do external mastic in Avongrove?
Yes, Avongrove is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. A flexible sealant is the right fill.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you work at height?
It depends on the height and the site. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What external mastic looks like in Avongrove
Historic houses like Cambusnethan House (about 4.1 miles east) are a reminder that the area around Avongrove has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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 Hamilton Central station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Earnock High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Hamilton South Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Avongrove is about 1 mile south of Hamilton, in South Lanarkshire. Whether you’re in the middle of Avongrove or further out, external mastic is available for homes and businesses alike. Our area takes in 139 places across South Lanarkshire, large and small. We also work in Glasgow, around 11 miles away.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What affects the quote in Avongrove
You’ll get a clear quote before any work starts. It takes into account:
- Mould in or behind the old joints
- How easy the joints are to reach
- The product the joint needs
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What we need to know
Photos help, but a description is a good start. Please mention:
- The type of property
- Roughly how big the job is
- Photos by email, if that’s easy
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Keeping the joints in good condition
So the new joints stay in good condition:
- Leave the joints unpainted unless we’ve said otherwise
- Act on the first splits you see
- Walk round the building once a year and look at the joints
- Keep soil, plants and ivy away from the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.
How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Outside jobs in Avongrove need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Keep children and pets away from the work area
