External mastic for homes and businesses in Marden Beech
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We’re often asked to deal with rigid filler in a joint that should flex and panel joints letting water in, across façade panels, brickwork movement joints and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Marden Beech is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Signs you need external mastic in Marden Beech
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we’re asked about most:
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
- Sealant pulling away from one side of the joint
If you let a flat or house near Marden station, split movement joints are easy to miss on a rental until damp shows inside.

- Whether they seal over old material or remove it
- Whether they’re fully insured
- What happens if the job turns out different
Honest limits
To be straight with you, some problems need a different trade:
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
- Movement that is more than a sealant joint can take
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Different surfaces, different methods
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.

What affects the cost of external mastic
We quote each job individually. These are the things that affect it:
- The size of the job
- How easy the joints are to reach
- How many areas need sealing
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Any access issues, like height or stairs
- The address or postcode of the job
- The type of property
- Photos by email, if that’s easy

Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together, and access only has to be arranged once. Older cottages and farmhouses around Marden Beech can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Your questions about external mastic in Marden Beech
I let a flat near Marden station. Can you help?
Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover Marden Beech for external mastic?
Yes, Marden Beech is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
What is a movement joint?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, large or small.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Outside joints around Marden Beech
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Michael and All Angels Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Marden Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
