External mastic in Petteridge
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. Common call-outs are for weathered mastic that no longer stretches and joints pointed up with cement by mistake, on brickwork movement joints, joints between brick and frames and façade panels.
Somewhere as small as Petteridge, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

What we’re called out for in Petteridge
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
Common reasons people contact us are:
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
- Movement joints with cracked, split or missing sealant
Schools such as Brenchley and Matfield Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before booking
- What the cure time is
- Is VAT in the price?
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
Quotes for external mastic in Petteridge
We don’t publish a price list, because no two jobs are the same. What we look at:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Working hours on commercial sites
- The number of rooms or windows
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
What we need to know
When you contact us, it’s useful to know:
- The address or postcode of the job
- Whether it’s a home or a business
- Any previous sealing or DIY work
- A few pictures by email, if you can
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.

When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
- Adding movement joints to masonry that has none
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

It depends on the building. Send us pictures and a rough idea of the height, and we’ll confirm what access is needed.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Will it make a mess?

Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can I do it myself?

The process
Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. In a small place like Petteridge, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in

External mastic in Petteridge: local notes
Historic houses like Scotney Castle (about 3.8 miles south) are a reminder that the area around Petteridge has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Ebenezer Church (Matfield), older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Paddock Wood station, outside joints that have cracked can let damp into a rental, so check them between lets.

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Petteridge 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 play a part.
