External mastic in Ulcombe
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. We work on concrete & block, façade panels and copings & trims, and people most often call us about brick movement joints where the sealant has split and failed sealant between panels on a façade.
Outside joints can only be sealed when they’re dry, so work in Ulcombe is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Why it’s worth doing now in Ulcombe
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. In a small place like Ulcombe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why choose Mr Mastic in Ulcombe

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Make sure movement joints aren’t pointed over
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
- Clear growth from the base of walls and joints
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
What happens on the day
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work normally takes anything from a few hours to several days, depending on the building. In a small place like Ulcombe, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
External mastic in Ulcombe: local notes
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. Historic houses like Leeds Castle (about 2.5 miles north) are a reminder that the area around Ulcombe 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.
Homes close to All Saints Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Ulcombe Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Harrietsham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.

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.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
