Normans' Bay: your questions answered
Will you come out to Normans' Bay?
Yes, Normans' Bay is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is external mastic in a coastal place like Normans' Bay any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
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 so it can flex with the joint.
Can a movement joint be filled with mortar?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
How long does the job take?
Most jobs take a few hours to a few days, depending on the length of joint and the access, including the preparation. We’ll confirm how long when we quote.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
How do I get a quote for external mastic in Normans' Bay?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
External mastic in Normans' Bay
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 take the old material out and do it properly. We work on façade panels, brickwork movement joints and concrete & block, and the jobs we see most are movement joints filled with mortar instead of sealant and failed seals between different materials.
External sealant needs dry, clean surfaces, so work around Normans' Bay is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Related advice
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Normans' Bay, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
What you get with us
- Neat joints and a tidy finish
- Any old sealant cut out fully, not covered over
- Sealant colour chosen to suit
- Domestic, commercial and hotel work
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Do you need external mastic in Normans' Bay?
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for these signs:
- Leaking joints around cladding and façade panels
- Movement joints filled with mortar instead of sealant
- Failed seals between different materials
- Weeds or debris growing in open joints
Around Normans' Bay, as everywhere, external mastic is only as good as the preparation behind it.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Deal with leaking gutters that soak the joints below
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
- Check external joints each spring
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 cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
When something else is needed
We’ll always be straight with you, so here’s what sealant can’t fix:
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Outside joints around Normans' Bay
Normans' Bay is within about 1 mile 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Normans Bay station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Wherever two materials meet, they move differently. A flexible sealant bridges the two.
