External & façade joints in Danaway, Kent
Our applicators work in Danaway on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
External mastic in Danaway, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We work on façade panels, joints between brick and frames and concrete & block, and common reasons people get in touch are cracked joints where brick meets render or frames and panel joints letting water in.
Outside joints can only be sealed when they’re dry, so work in Danaway is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Landlords and letting agents in Danaway can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
When to call us in Danaway
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
The problems people generally mention when they call include:
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
- Leaking joints around cladding and façade panels
If you look after a building such as Borden Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- How long the guarantee is
- How hidden problems are handled
- Whether they’re fully insured
- Which sealant they’ll use, and why
Outside joints around Danaway
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Peter and St Paul include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Newington station? Then split movement joints are easy to miss on a rental until damp shows inside.

How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- The amount of work
- Whether old sealant or filler has to be cut out
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- The rough size of the job
- If someone has resealed it before
- Where the job is, and your postcode
- A few pictures by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Clear growth from the base of walls and joints
- Avoid pressure-washing directly into sealant joints
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Somewhere as small as Danaway, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Let us know about parking restrictions

Advice
Your questions about external mastic in Danaway
Do you work for landlords with property near Newington station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is Danaway in your area for external mastic?
Yes. We work across London and the South East, and Danaway is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
Do you have insurance?
Yes. Mr Mastic is fully insured.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.

How the job changes by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
