External Mastic in Maiden's Green
We cover Maiden's Green for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.
- Old sealant gone brittle and cracked
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
External mastic in Maiden's Green, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. Common call-outs are for gaps where render, brick and frames meet and sealant that has lost its bond to the brick or render, on joints between brick and frames, brickwork movement joints and façade panels.
Older homes in small places like Maiden's Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Walls and rooflines in Maiden's Green
With historic houses such as St Leonard's Hill (about 3 miles north-east) nearby, there’s older building stock in the area around Maiden'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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Martins Heron station, outside joints that have cracked can let damp into a rental, so check them between lets.

What affects the cost of external mastic
We quote each job individually. This is what makes a difference:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- How easy the joints are to reach
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- The address or postcode of the job
- How we’d reach the joints
- The type of property
Every job is quoted individually. Just phone 0345 464 0079 or drop us an email with the details and send pictures if you have them.
Questions from Maiden's Green
Can you help a landlord with a rental near Martins Heron station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is Maiden's Green within the area you cover?
Yes, Maiden's Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do you need external mastic in Maiden's Green?
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.
Look out for any of the following:
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
- Panel joints letting water in
- Water getting into walls through failed joints
In the older streets around Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Can I do it myself?
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 DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Different surfaces, different methods
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. For a village or hamlet like Maiden's Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- 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.
Before we arrive
- Mention any tricky access
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.

Keeping the joints in good condition
Looking after new joints is easy:
- Never let anyone fill a movement joint with mortar
- Point out the joints to other trades
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
