What external mastic looks like in Fox Street
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Castle House (about 3.2 miles north-east) are a reminder that the area around Fox Street has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Roach Vale Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Hythe station? Then split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Church of St John, the joints between older walls, newer extensions and the roofline need a sealant that can move.

External mastic in Fox Street, done properly
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on joints between brick and frames, façade panels and render & cladding joints, and people most often call us about moss and dirt in joints with no sealant left and movement joints filled with mortar instead of sealant.
Outside joints can only be sealed when they’re dry, so work in Fox Street is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

How to look after the new joints
So the new joints stay in good condition:
- Check external joints each spring
- Keep water from gutters off the wall
- Do not let climbing plants root in the sealant
- Ask before painting over external sealant
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take anything from a few hours to several days, depending on the building. Somewhere like Fox Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

Can I do it myself?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Surface by surface
