External & façade joints in Ditton, Kent
Our applicators work in Ditton on sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Old sealant gone brittle and cracked
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
What happens if it’s left?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Homes in smaller places like Ditton 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.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

How we handle external mastic in Ditton
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 use one wherever it does. We work on concrete & block, render & cladding joints and façade panels, and common reasons people get in touch are panel joints letting water in and sealant that has lost its bond to the brick or render.
In a smaller place like Ditton, some homes face open ground, and walls and rooflines facing the weather take the worst of it. Joints on those sides are generally the first to go.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Ditton buildings and 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. With historic houses such as Starkey Castle (about 4.8 miles north) nearby, there’s older building stock in the area around Ditton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near St Peter's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Ditton Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Aylesford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. A visit to Ditton is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Clear the area around the work

How the job changes by surface
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.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What affects the cost of external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- The type of sealant required
- The old material and how stubborn it is
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
What to tell us when you ask for a quote:
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- The rough size of the job
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or drop us an email.
Aftercare tips
To keep the joints looking good and working properly:
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

FAQs for Ditton
Is Ditton in your area for external mastic?
Yes. We work across London and the South East, and Ditton is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Is Ditton within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
What is a movement joint?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
