What external mastic looks like in Kit's Coty
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Starkey Castle (about 3.4 miles north-west) are a reminder that the area around Kit's Coty has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Schools such as Tunbury Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Aylesford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Typical jobs include failed seals between different materials and sealant that has lost its bond to the brick or render, on façade panels, render & cladding joints and copings & trims.
Older homes in small places like Kit's Coty may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in.

How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the building. Somewhere like Kit's Coty needs a little journey planning: 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.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Your questions about external mastic in Kit's Coty
Can you help a landlord with a rental near Aylesford station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Kit's Coty?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
How long does the job take?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on the building. We will tell you when we quote.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Cracks in the bricks or render themselves, away from the joints
- Walls that need new movement joints cut into them
- Render that’s blown, hollow or coming away
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Where we work in Kit's Coty
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
- Copings & trims
- Façade panels
- Concrete & block
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Look over the joints every year, ideally after winter
- Do not let climbing plants root in the sealant
- Check the sealant is paintable before painting near it
- Have failed joints looked at early
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.

For anyone letting property in or around Kit's Coty, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.

When to call us in Kit's Coty
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Keep an eye out for any of the following:
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
If you live in an older home near St Alban's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What to look for in a quote
- How long the guarantee is
- How much experience the applicator has
- What happens if the job turns out different
- Whether you can choose the colour
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. Older cottages and farmhouses around Kit's Coty can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
Why us?
- Fully insured
- Approved under the ARBOMaster scheme
- Sanitary silicone with an anti-fungal additive in wet areas
- We agree the colour with you first

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
