Movement joints in Bellsbank need attention? We remove the old material, prepare the joints and seal them properly.

External mastic in Bellsbank
On houses, flats and commercial buildings across Bellsbank, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. Typical jobs include brick movement joints where the sealant has split and water getting into walls through failed joints, across joints between brick and frames, façade panels and copings & trims.
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.
All our work is covered by our 12-month guarantee.

Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Bellsbank and across South Ayrshire. Several sites can be quoted together, and we are fully insured for the work.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Do you need external mastic in Bellsbank?
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall.
These are the problems we’re asked about most:
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
- Joints with sealant missing in places
- Leaking joints around cladding and façade panels
If you look after a building such as Doon Academy, its movement joints, gutters and trims need looking after like any other building’s.

What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. 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.
- First, the joints are inspected and the access agreed.
- 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.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Bellsbank: your questions answered
Is Bellsbank in your area for external mastic?
Yes, Bellsbank is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Is external mastic in Bellsbank guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Are you insured?
Yes. We are fully insured for every job we do.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Clear growth from the base of walls and joints
- Wash walls gently around the sealant
- Fix overflowing gutters above sealed joints
- Check external joints each spring
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
