How we handle external mastic in Glenlomond
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include joints pointed up with cement by mistake and gaps where render, brick and frames meet, on concrete & block, façade panels and brickwork movement joints.
External sealant needs dry surfaces, so outdoor work around Glenlomond is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

What happens on the day
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Around Glenlomond, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Advice
Why act early in Glenlomond
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a place like Glenlomond, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

FAQs for Glenlomond
What guarantee comes with external mastic in Glenlomond?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Glenlomond?
Yes. Glenlomond is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How the job changes by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Outside joints around Glenlomond
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.
If you live in an older home near Easter Balgedie church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we’re called out for in Glenlomond
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Keep an eye out for these signs:
- Weeds or debris growing in open joints
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
Around Glenlomond, as everywhere, external mastic is only as good as the preparation behind it.
Questions to ask before booking

- Is VAT in the price?
