Questions from Wintershill
Will you come out to Wintershill?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Hedge End station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
How do I get a quote for external mastic in Wintershill?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Should I point up the gap in my brickwork?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, large or small.

External mastic in Wintershill: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Hedge End station, outside joints that have cracked can let damp into a rental, so check them between lets.

What happens if it’s left?
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. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Wintershill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What happens on the day
Once we are on site, we compare the joints with what we discussed. 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. In a small place like Wintershill, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- 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.
- We apply the sealant, tool it and check the whole run.

How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so the movement is taken up.
Aftercare tips
Aftercare is simple:
- Keep soil, plants and ivy away from the joints
- Deal with leaking gutters that soak the joints below
- Leave the joints unpainted unless we have said otherwise
- Never let anyone fill a movement joint with mortar
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Common problems we fix in Wintershill
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
Common reasons people contact us are:
- Cracked joints where brick meets render or frames
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
For site and facilities teams at buildings such as Wyvern Technology College, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
