- Water getting into walls through failed joints
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
- Check external joints each spring
- Fix overflowing gutters above sealed joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
External mastic in Woolley Green
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on copings & trims, joints between brick and frames and render & cladding joints, and people most often call us about movement joints with cracked, split or missing sealant and panel joints letting water in.
Older homes in small places like Woolley Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Woolley Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

Woolley Green questions
Will you come out to Woolley Green?
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 cover Woolley Green for external mastic?
Yes. Our work covers London and the South East, and Woolley Green is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
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.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Walls and rooflines in Woolley Green
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. With historic houses such as Harleyford Manor (about 3.3 miles north-west) nearby, there’s older building stock in the area around Woolley Green as well as newer homes. 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 Saint John the Evangelist, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Manor Green School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Maidenhead station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Leave it or put it right?
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Around Woolley 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, ring 0345 464 0079 or email us for an honest opinion and a quote.
