Crockleford Heath External Mastic
Movement joints in Crockleford Heath need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Never let anyone fill a movement joint with mortar
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
- Do not let climbing plants root in the sealant
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
External mastic in Crockleford Heath
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. Common call-outs are for joints pointed up with cement by mistake and leaking joints around cladding and façade panels, across joints between brick and frames, concrete & block and copings & trims.
Around Crockleford Heath, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
Whatever the size of the job, you get the same 12-month guarantee.

What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Crockleford Heath, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Crockleford Heath: your questions answered
Do you work for landlords with property near Hythe station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you cover smaller places like Crockleford Heath?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What we are called out for in Crockleford Heath
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
Keep an eye out for any of the following:
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
Castle House, about 3.7 miles north, is one of the historic houses in the wider area around Crockleford Heath.
What to look for in a quote
- What the cure time is
- What happens if the job turns out different
- The length of the guarantee
- Whether you can choose the colour
What happens if it’s left?
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Older cottages and farmhouses around Crockleford Heath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
