Haggs External Mastic
Our applicators work in Haggs on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
What we’re called out for in Haggs
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Look out for any of the following:
- Moss and dirt in joints with no sealant left
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
Managing a site like Abronhill High School? Then larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include

- Whether the sealant suits the joint
- Is VAT in the price?
- Whether they’re fully insured
How we handle external mastic in Haggs
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. We work on copings & trims, joints between brick and frames and brickwork movement joints, and the jobs we see most are failed seals between different materials and failed sealant between panels on a façade.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Outside joints on exposed walls work hard.
Every job comes with a one-year guarantee, wherever you are in Falkirk.

What affects the quote in Haggs
The price is agreed before any work begins. It’s based on:
- Which sealant suits the joint
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- How much there is to do
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

The work usually takes anything from a few hours to several days, depending on the building. Around Haggs, distance and access matter more than parking. Let us know how to find you and how to reach the joints.

Related advice
Why act early in Haggs
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. In an older home around Haggs, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Walls and rooflines in Haggs
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
For an older house near a landmark such as Haggs Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Cumbernauld station? Then split movement joints are easy to miss on a rental until damp shows inside.

Haggs questions

Yes. Haggs is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Cumbernauld station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
