How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Tile Hurst, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

About our external mastic in Tile Hurst
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We work on render & cladding joints, façade panels and copings & trims, and the jobs we see most are joints where the bead has come unstuck and rigid filler in a joint that should flex.
Around Tile Hurst, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
All our work comes with our 12-month guarantee, wherever you are in East Sussex.

FAQs for Tile Hurst
Is Tile Hurst in your area for external mastic?
Yes. We work across London and the South East, and Tile Hurst is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Polegate station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move and needs a flexible seal, not mortar.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
When something else is needed
In fairness, some problems need a different trade:
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
- Adding movement joints to masonry that has none
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.

Surface by surface
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
How we quote for external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- The number and length of the joints
- When we can work, for business premises
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before we start.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- The rough size of the job
- Where the job is, and your postcode
- The type of property
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Signs you need external mastic in Tile Hurst
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Keep an eye out for these signs:
- Leaking joints around cladding and façade panels
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Hard, crazed mastic that has stopped moving
If you let a flat or house near Polegate station, outside joints that have cracked can let damp into a rental, so check them between lets.

- How the surfaces are prepared before sealing

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Outside joints around Tile Hurst
With historic houses such as Michelham Priory (about 1.1 miles south-west) nearby, there’s older building stock in the area around Tile Hurst as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Zoar Strict Baptist Chapel, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Grovelands Community Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Wash walls gently around the sealant
- Do not let climbing plants root in the sealant
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
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.
