What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere like Eastwood needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Advice
About our external mastic in Eastwood
On houses, flats and commercial buildings across Eastwood, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Common call-outs are for hard, crazed mastic that has stopped moving and rigid filler in a joint that should flex, on concrete & block, joints between brick and frames and façade panels.
External sealant needs dry, clean surfaces, so work around Eastwood is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Check external joints each spring
- Do not let climbing plants root in the sealant
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
Walls and rooflines in Eastwood
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Leeds Castle (about 3.4 miles north-west) are a reminder that the area around Eastwood has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Historic houses such as Leeds Castle, about 3.4 miles north-west, show how far back building around Eastwood goes. If you let a flat or house near Harrietsham station, split movement joints are easy to miss on a rental until damp shows inside.

When to call us in Eastwood
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Common reasons people contact us are:
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
For site and facilities teams at buildings such as Ulcombe Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Landlord and commercial work in Eastwood

Landlords and letting agents in Eastwood can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Older cottages and farmhouses around Eastwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are 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.
Eastwood questions
Is Eastwood within the area you cover?
Yes, Eastwood is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Eastwood for external mastic?
Yes. We work across London and the South East, and Eastwood is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working, and the wall may crack nearby. We’ll reseal it with a flexible sealant.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before work begins, matched as closely as the range allows.
How much does external mastic cost in Eastwood?
Size, access and the old material all affect the cost. Call for a quick quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
