How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Concrete and blockwork
Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.
About our external mastic in Shutford
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. Typical jobs include weathered mastic that no longer stretches and damp patches traced to an open external joint, on joints between brick and frames, façade panels and concrete & block.
External sealant needs dry, clean surfaces, so work around Shutford is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
For landlords and businesses
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 that we can handle for you.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Do you need external mastic in Shutford?
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
Most people get in touch after spotting one of these:
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
- Rain getting behind render or cladding at a joint
- Brick movement joints where the sealant has split
If you let a flat or house near Banbury station, split movement joints are easy to miss on a rental until damp shows inside.

Your questions about external mastic in Shutford
Can you help a landlord with a rental near Banbury station?
Yes, we work for landlords and letting agents. You can call 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 Shutford?
Yes. Shutford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year.
What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere like Shutford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- 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.
Before we arrive
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Outside joints around Shutford
With historic houses such as Broughton Castle (about 2.4 miles south-east) nearby, there’s older building stock in the area around Shutford 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Martin, older walls, gutters and the joints where extensions meet them need a flexible sealant.
