External mastic for homes and businesses in Kippington
For buildings in Kippington, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We are often asked to deal with joints where the bead has come unstuck and weathered mastic that no longer stretches, across concrete & block, joints between brick and frames and brickwork movement joints.
Outbuildings, garages and conservatories around homes in places like Kippington add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of external mastic
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- How easy the joints are to reach
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- Where the property is
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep movement joints as flexible joints, not mortar
- Keep water from gutters off the wall
- Point out the joints to other trades
- Have failed joints looked at early
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Homes in smaller places like Kippington can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
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 we need extra access for height. We take all of that into account in your quote.

How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. For a job in Kippington, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

What external mastic looks like in Kippington
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. With historic houses such as Knole House (about 1.2 miles east) nearby, there’s older building stock in the area around Kippington as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as St Thomas' Catholic Primary School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Sevenoaks station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Common problems we fix in Kippington
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Gaps where render, brick and frames meet
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Brick movement joints where the sealant has split
If you live in an older home near Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
FAQs for Kippington
Do you cover smaller places like Kippington?
Yes. Kippington is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Kippington for external mastic?
Yes. Our work covers London and the South East, and Kippington is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
