External & façade joints in Lamberhurst Quarter, Kent

- Joints pointed up with cement by mistake

- Sealant that has lost its bond to the brick or render
How we handle external mastic in Lamberhurst Quarter
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. If you have rigid filler in a joint that should flex and cracked joints where brick meets render or frames, we can help, whatever the surface.
Somewhere as small as Lamberhurst Quarter, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Our work is backed for twelve months, in Lamberhurst Quarter and everywhere else we cover.

Surface by surface
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.

What else we do in Lamberhurst Quarter
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Check external joints each spring
- Fix overflowing gutters above sealed joints
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.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering

What we are called out for in Lamberhurst Quarter
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 and make things worse.
Most people get in touch after spotting one of these:
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
For landlords with property near Frant station, split movement joints are easy to miss on a rental until damp shows inside.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Your questions about external mastic in Lamberhurst Quarter
Do you work for landlords with property near Frant station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Lamberhurst Quarter?
Yes. Lamberhurst Quarter is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How do I get a quote for external mastic in Lamberhurst Quarter?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
