How we handle external mastic in Kiddington
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. Typical jobs include old sealant gone brittle and cracked and joints pointed up with cement by mistake, across joints between brick and frames, façade panels and concrete & block.
External sealant needs dry, clean surfaces, so work around Kiddington is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job.

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Kiddington 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.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive

Landlord and commercial work in Kiddington
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What we are called out for in Kiddington
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Look out for any of the following:
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Hard, crazed mastic that has stopped moving
For an older house near a landmark such as Church of St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before booking anyone
- What guarantee comes with the work
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
- Are they insured?
Why it’s worth doing now in Kiddington
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. Around Kiddington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why Kiddington customers choose us
- Neat joints and a tidy finish
- White, clear, grey or coloured to suit, where the product allows
- Anti-fungal silicone where joints get wet
- A 12-month guarantee on all work

Honest limits
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
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

External mastic in Kiddington: local notes
With historic houses such as Blenheim Palace (about 4.6 miles south) nearby, there’s older building stock in the area around Kiddington as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Charlbury station, split movement joints are easy to miss on a rental until damp shows inside.

FAQs for Kiddington
Will you come out to Kiddington?
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.
Can you help a landlord with a rental near Charlbury station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Should I point up the gap in my brickwork?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. We will reseal it with a flexible sealant.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it.
