External Mastic in Crocketford
Our applicators work in Crocketford on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

External mastic in Crocketford
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we don’t skip that step. Common call-outs are for gaps where render, brick and frames meet and movement joints filled with mortar instead of sealant, across copings & trims, joints between brick and frames and façade panels.
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, so they need a sealant that moves with the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Signs you need external mastic in Crocketford
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
These are the problems we are asked about most:
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
Around Crocketford, as everywhere, external mastic is only as good as the preparation behind it.
What your quote should include
- The length of the guarantee
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- What happens if the job turns out different

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. Around Crocketford, 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.

Crocketford: your questions answered
Will you come out to Crocketford?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is Crocketford in your area for external mastic?
Yes, Crocketford is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Where do you work from?
Mr Mastic is based in Crawley. We cover Crocketford and the rest of Dumfries and Galloway, along with the rest of our area.
External mastic in Crocketford: local notes
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 where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
For jobs in and around Crocketford, choosing the right material for each joint is as important as a tidy finish.

What affects the quote in Crocketford
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

- Pictures of the joints, sent by email

The process
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job generally takes a few hours to a few days, depending on the length of joint and the access. 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 walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Advice
Surface by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
