- Water getting into walls through failed joints
- Movement joints filled with mortar instead of sealant
- Failed seals between different materials
Why act early in Woolage Green
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. Around Woolage Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Common problems we fix in Woolage Green
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Any of these means the joints need attention:
- Plants rooting in failed movement joints
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
- Leaking joints around cladding and façade panels
For landlords with property near Snowdown station, split movement joints are easy to miss on a rental until damp shows inside.

Woolage Green buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Goodnestone Park (about 3.2 miles north) are a reminder that the area around Woolage Green has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of St Margaret, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Quotes for external mastic in Woolage Green

- Working hours on commercial sites
- How many rooms, windows or areas are involved
- Access and height
- Whether there’s mould to deal with
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.

The process
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Woolage Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Tell us if parking is tricky

Advice
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Concrete & block
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that is what we use. Tell us what the building has when you get in touch.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
FAQs for Woolage Green
Can you do external mastic in Woolage Green?
Yes. We work across London and the South East, and Woolage Green is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Will you come out to Woolage Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long does the job take?
Most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll confirm how long when we quote.
How long does external mastic last?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working. We will reseal it with a flexible sealant.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
What colours does the sealant come in?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
