External mastic in Palmer's Green
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Typical jobs include failed sealant between panels on a façade and sealant pulling away from one side of the joint, across copings & trims, brickwork movement joints and joints between brick and frames.
Around Palmer's Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
Every job comes with a 12-month guarantee.

Advice
When to call us in Palmer's Green
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
The problems people generally mention when they call include:
- Sealant pulling away from one side of the joint
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
If you let a flat or house near Paddock Wood station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before booking
- What preparation is included
- Who does the work, and how experienced they are
- What product goes in the joint
- Which colour the sealant will be
What sealant work cannot fix
It helps to know what we cannot do:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Façade panels
- Copings & trims

Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
For landlords and businesses
Housing providers, facilities teams and property managers book us too in Palmer's Green and across Kent. Several sites can be quoted together, and we’re fully insured.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Why it’s worth doing now in Palmer's Green
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 so it’s worth doing right. Older cottages and farmhouses around Palmer's Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Outside joints around Palmer's Green
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. With historic houses such as Scotney Castle (about 4 miles south) nearby, there’s older building stock in the area around Palmer's Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Parish Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Brenchley and Matfield Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Leave the joints unpainted unless we’ve said otherwise
- Get split or bare joints resealed while the damage is small
- Keep soil, plants and ivy away from the joints
- Wash walls gently around the sealant
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.

How long will you be here?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll tell you when we quote.
What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
