How we handle external mastic in Stone Cross
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. Typical jobs include leaking joints around cladding and façade panels and sealant that has lost its bond to the brick or render, across brickwork movement joints, joints between brick and frames and render & cladding joints.
Around Stone Cross, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. For a job in Stone Cross, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires 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
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

What external mastic looks like in Stone Cross
Stone Cross is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St Luke's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Pevensey & Westham station? Then split movement joints are easy to miss on a rental until damp shows inside.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.

When it isn’t the sealant
It helps to know what we can’t do too:
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Façade panels
- Copings & trims
- Joints between brick and frames
- Brickwork movement joints
- Concrete & block
- Render & cladding joints
Do you need external mastic in Stone Cross?
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
These are the problems we’re asked about most:
- Joints pointed up with cement by mistake
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Plants rooting in failed movement joints
For site and facilities teams at buildings such as Stone Cross School, larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
What affects the cost of external mastic
Your quote is based on your job. We look at:
- Whether there’s mould to deal with
- Which sealant suits the joint
- Any working-time requirements on site
- Access and height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What to tell us for a quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved

Your questions about external mastic in Stone Cross
I let a flat near Pevensey & Westham station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Stone Cross within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. Homes in smaller places like Stone Cross can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
