Walls and rooflines in Findon
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Ecclesden Manor (about 3.8 miles south-west) are a reminder that the area around Findon has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as St John the Baptist CofE Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to West Worthing station? Then split movement joints are easy to miss on a rental until damp shows inside.

About our external mastic in Findon
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. Common call-outs are for failed sealant between panels on a façade and sealant that has lost its bond to the brick or render, on brickwork movement joints, copings & trims and joints between brick and frames.
Older homes in small places like Findon 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like Findon, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Common questions in Findon
I let a flat near West Worthing station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Findon within the area you cover?
Yes, Findon is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint does not draw the eye.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What we’re called out for in Findon
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Common reasons people contact us include:
- Plants rooting in failed movement joints
- Joints pointed up with cement by mistake
- Leaking joints around cladding and façade panels
- Failed seals between different materials
Homes close to The Parish Church of St John the Baptist include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Findon 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.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Mention any parking rules near the property
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Structural movement, which needs a surveyor or engineer
- Cracked brickwork or render that needs a builder or plasterer
- Damp that is not coming from the joint
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Looking after it afterwards
After the cure time, these simple habits help:
- Point out the joints to other trades
- Walk round the building once a year and look at the joints
- Keep movement joints as flexible joints, not mortar
- Don’t let climbing plants root in the sealant
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into 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.
Different surfaces, different methods
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap so the sealant is not too deep.
