How we handle external mastic in Upper Eashing
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on concrete & block, copings & trims and render & cladding joints, and the jobs we see most are panel joints letting water in and old sealant gone brittle and cracked.
Around Upper Eashing, 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.
We stand behind the work with a one-year guarantee.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are set on DIY, put the effort into 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.

What affects the cost of external mastic
Every job gets its own quote. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The number and length of the joints
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What external mastic looks like in Upper Eashing
Historic houses like Loseley Park (about 2.7 miles north-east) are a reminder that the area around Upper Eashing has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as St Mark and All Saints Church of England Primary are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Mark's Church and Community Centre, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Signs you need external mastic in Upper Eashing
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
If you let a flat or house near Godalming station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Upper Eashing, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs 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.
Before we arrive
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Common questions in Upper Eashing
Do you cover Upper Eashing for external mastic?
Yes, Upper Eashing is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.

When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Should I try DIY first?
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.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Surface by surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Subsidence or other structural problems
- Damp that is not coming from the joint
- Walls that need new movement joints cut into them
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Render & cladding joints
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
- Concrete & block
- Copings & trims
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Landlords and letting agents in Upper Eashing can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
