About our external mastic in Funtley
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We are often asked to deal with panel joints letting water in and joints where the bead has come unstuck, across concrete & block, copings & trims and brickwork movement joints.
Older homes in small places like Funtley may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Big or small, it’s backed by our 12-month guarantee.

How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Funtley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Funtley: your questions answered
Does the coastal weather in Funtley 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.
Do you cover smaller places like Funtley?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does external mastic take?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What affects the quote in Funtley
There’s no set price list. The quote depends on:
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- The amount of work
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
We don’t publish a price list. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or email us.
Funtley buildings and the weather
Funtley is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
If you look after a building such as Orchard Lea Infant School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of St Francis, an extension built onto an older house moves differently, and the joint between them takes the strain.

When to call us in Funtley
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
If you can see any of these, it’s time to have the joints looked at:
- Brick movement joints where the sealant has split
- Panel joints letting water in
- Movement joints filled with mortar instead of sealant
- Cracked joints where brick meets render or frames
If you let a flat or house near Fareham station, split movement joints are easy to miss on a rental until damp shows inside.

Why act early in Funtley
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Funtley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Surface by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
