- Panel joints letting water in
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
About our external mastic in Chipping Norton
On houses, flats and commercial buildings across Chipping Norton, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We’re often asked to deal with failed seals between different materials and movement joints filled with mortar instead of sealant, across render & cladding joints, joints between brick and frames and copings & trims.
Outbuildings, garages and conservatories around homes in places like Chipping Norton add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Each job carries a 12-month guarantee.

Common questions in Chipping Norton
Can you help a landlord with a rental near Kingham station?
Yes, we work for landlords and letting agents. 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 we start.
Will you come out to Chipping Norton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before we start from the range available.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Walls and rooflines in Chipping Norton
With historic houses such as Chastleton House (about 4.2 miles west) nearby, there’s older building stock in the area around Chipping Norton as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Chipping Norton School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. In a smaller place like Chipping Norton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- Clear items away from the joints we are working on

What the job involves on each surface
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.
Why it’s worth doing now in Chipping Norton
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Around Chipping Norton, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.
What you get with us
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
- An ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over
What we’re called out for in Chipping Norton
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Common reasons people contact us are:
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
If you let a flat or house near Kingham station, outside joints that have cracked can let damp into a rental, so check them between lets.
Questions to ask before booking
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- What happens if they find a problem under the old sealant
- What the cure time is

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
