Ladwell buildings and the weather
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.
For site and facilities teams at buildings such as John Keble Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Ladwell is about 2 miles north of Chandler's Ford, in Hampshire. Whether you are in the middle of Ladwell or further out, we cover external mastic for every kind of property, from flats and houses to offices and hotels. Across Hampshire, we cover 683 places, and Ladwell is one of them. Southampton is on our list too, around 7 miles away.

External mastic in Ladwell
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you have movement joints with cracked, split or missing sealant and weathered mastic that no longer stretches, we can help, on joints between brick and frames, façade panels and brickwork movement joints alike.
In a village or hamlet like Ladwell, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, it’s backed by our one-year guarantee in Ladwell and across Hampshire.

Why it’s worth doing now in Ladwell
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Ladwell, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
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 call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Landlord and commercial work in Ladwell
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
For anyone letting property in or around Ladwell, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
When to call us in Ladwell
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
Common reasons people contact us are:
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Movement joints filled with mortar instead of sealant
- Joints where the bead has come unstuck
Letting a property close to Chandlers Ford station? Then split movement joints are easy to miss on a rental until damp shows inside.

Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long should I leave it?
Cure times vary by product. We tell you how long to leave it before we go.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Ladwell, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- On commercial sites, let us know about site rules
