Can I do it myself?
If you are set on DIY, put the effort into 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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
External mastic for homes and businesses in Hilden Park
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint doesn’t stand out. Typical jobs include joints with sealant missing in places and old sealant gone brittle and cracked, on copings & trims, façade panels and render & cladding joints.
In a village or hamlet like Hilden Park, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
There’s a 12-month guarantee on every job, whatever its size.

How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Hilden Park needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any parking rules near the property
- Clear the area around the work
- On commercial sites, let us know about site rules

Advice
Why it’s worth doing now in Hilden Park
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Hilden Park can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Landlord and commercial work in Hilden Park
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
For anyone letting property in or around Hilden Park, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
How the job changes by surface
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
What we seal

Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Clear growth from the base of walls and joints
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
- Check the sealant is paintable before painting near it
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.

What external mastic looks like in Hilden Park
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Ightham Mote (about 3.4 miles north) are a reminder that the area around Hilden Park has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Stocks Green Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Hildenborough station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Parish Church of St John include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
