About our external mastic in Ebbsfleet
For buildings in Ebbsfleet, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have moss and dirt in joints with no sealant left and joints where the bead has come unstuck, we can help, on joints between brick and frames, façade panels and copings & trims alike.
Outside joints can only be sealed when they’re dry, so work in Ebbsfleet is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
All our work comes with our one-year guarantee, wherever you are in Kent.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Somewhere like Ebbsfleet needs a little journey planning: let us know about lanes, gates and parking. 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.
- The old mastic and anything lodged in the joint is removed.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Advice
Aftercare tips
So the new joints stay in good condition:
- Look over the joints every year, ideally after winter
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.
Ebbsfleet questions
Does the coastal weather in Ebbsfleet affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Ebbsfleet?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Can you do several jobs on one visit?
Yes. Just list everything you need.

External mastic in Ebbsfleet: local notes
Ebbsfleet is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Thanet Parkway station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Quex Park, about 3.8 miles north, is one of the historic houses in the wider area around Ebbsfleet, and older homes nearby need a sealant that suits their walls.

Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Ebbsfleet, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
