External mastic in Bishopbriggs, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on copings & trims, render & cladding joints and brickwork movement joints, and common reasons people get in touch are rigid filler in a joint that should flex and hard, crazed mastic that has stopped moving.
Scottish towns like Bishopbriggs mix older stone buildings with newer estates of brick, render and uPVC trims. Each has its own weak points: worn joints in old gutters, and dried-out movement joints in newer walls.
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.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Deal with leaking gutters that soak the joints below
- Get split or bare joints resealed while the damage is small
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
How the visit works
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. In a Scottish town like Bishopbriggs, parking is normally straightforward, though older centres can be tighter. For flats, mention the shared stair or door entry system.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Outside joints around Bishopbriggs
The west of Scotland is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out. With historic houses such as Provand's Lordship (about 3.2 miles south) nearby, there’s older building stock in the area around Bishopbriggs as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Bishopbriggs station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Bishopbriggs Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What the job involves on each surface
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. In Bishopbriggs, wind and rain soon get through failed outside joints. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Other services in Bishopbriggs
Do you need external mastic in Bishopbriggs?
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The most common problems we see are:
- Sealant pulling away from one side of the joint
- Rigid filler in a joint that should flex
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
For an older house near a landmark such as Colston Wellpark Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
