External Mastic in Sevenscore
Movement joints in Sevenscore need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re 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 doesn’t work out, we can still put it right.
About our external mastic in Sevenscore
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on brickwork movement joints, façade panels and joints between brick and frames, and common reasons people get in touch are rain getting behind render or cladding at a joint and plants rooting in failed movement joints.
Outside joints can only be sealed when they’re dry, so work in Sevenscore is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes as standard.

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Where a wall is exposed, as many are in small places like Sevenscore, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Walls and rooflines in Sevenscore
Sevenscore is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. If you let a flat or house near Thanet Parkway station, split movement joints are easy to miss on a rental until damp shows inside.

You do not need to know the technical terms. Just tell us:

What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Sevenscore, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

FAQs for Sevenscore
I let a flat near Thanet Parkway station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Sevenscore?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can a movement joint be filled with mortar?
No. Rigid materials can’t move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Sevenscore.
Aftercare tips
To keep the joints looking good and working properly:
- Clear growth from the base of walls and joints
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Make sure movement joints aren’t pointed over
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.
