External mastic in Cray's Pond, done properly
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. If you have movement joints with cracked, split or missing sealant and joints where the bead has come unstuck, we can put it right, on concrete & block, façade panels and joints between brick and frames alike.
Around Cray's Pond, 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.
Big or small, it’s backed by our 12-month guarantee in Cray's Pond and across Oxfordshire.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never let anyone fill a movement joint with mortar
- Clear growth from the base of walls and joints
- Deal with leaking gutters that soak the joints below
- Leave the joints unpainted unless we’ve said otherwise
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Honest limits
A few problems are outside what sealant work can do:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Do you need external mastic in Cray's Pond?
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
It’s worth asking for a quote if you see:
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
- Rain getting behind render or cladding at a joint
In the older streets around Church of St Leonard, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Cray's Pond buildings and the weather
With historic houses such as Basildon Park (about 2.2 miles south-west) nearby, there’s older building stock in the area around Cray's Pond as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as The Oratory Preparatory School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Goring & Streatley station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Why it’s worth doing now in Cray's Pond
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Around Cray's Pond, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

FAQs for Cray's Pond
Can you do external mastic in Cray's Pond?
Yes. We work across London and the South East, and Cray's Pond is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Will you come out to Cray's Pond?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you insured?
Yes. We are fully insured.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
When will the joints need doing again?
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.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. We will reseal it with a flexible sealant.
