External mastic in Moor Street, done properly
On houses, flats and commercial buildings across Moor Street, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on façade panels, concrete & block and render & cladding joints, and common reasons people get in touch are hard, crazed mastic that has stopped moving and joints pointed up with cement by mistake.
External sealant needs dry, clean surfaces, so work around Moor Street is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You get a 12-month guarantee, the same in Moor Street as everywhere else we work.

What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Around Moor Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. In a small place like Moor Street, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Tell us if parking is tricky

Advice
Moor Street buildings and the weather
Moor Street is close to 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Margaret, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Rainham (Kent) station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Signs you need external mastic in Moor Street
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
It’s worth asking for a quote if you see:
- Hard, crazed mastic that has stopped moving
- Panel joints letting water in
- Sealant pulling away from one side of the joint
- Failed seals between different materials
Schools such as Leigh Academy Rainham are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What else we do in Moor Street
Common questions in Moor Street
Does living near the coast affect external mastic in Moor Street?
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.
Do you cover smaller places like Moor Street?
Yes, Moor Street is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Are you fully insured?
Yes. Mr Mastic is fully insured.
How the job changes by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
- Damp that isn’t coming from the joint
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
