Willey Green External Mastic
External mastic across Willey Green and nearby, with every bit of old sealant taken out first.
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
External mastic in Willey Green
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on façade panels, concrete & block and render & cladding joints, and the jobs we see most are gaps where render, brick and frames meet and hard, crazed mastic that has stopped moving.
Around Willey Green, older buildings can be stone, brick or timber-framed, many with extensions added later. 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 is not right with it in that time, tell us and we’ll put it right.

Why it’s worth doing now in Willey Green
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. Where a wall is exposed, as many are in small places like Willey Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Do not let climbing plants root in the sealant
- Check external joints each spring
- Fix overflowing gutters above sealed joints
- Act on the first splits you see
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.

What external mastic looks like in Willey Green
Historic houses like Wanborough Manor (about 1.8 miles south) are a reminder that the area around Willey Green has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mark, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you let a flat or house near Wanborough station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Kings College Guildford? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
Is there a guarantee?
Yes. All our work carries our one-year guarantee.
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.

When something else is needed
New sealant can’t fix everything, and we’ll tell you before work begins. It won’t solve:
- Damp that isn’t coming from the joint
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Façade panels
- Joints between brick and frames
- Concrete & block
- Copings & trims
- Render & cladding joints
- Brickwork movement joints
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Willey Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
