Do you need external mastic in Caldecote?
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
These are the problems we’re asked about most:
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
- Failed seals between different materials
- Hard, crazed mastic that has stopped moving
Rented homes near Milton Keynes Central station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

About our external mastic in Caldecote
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on joints between brick and frames, copings & trims and render & cladding joints, and people most often call us about joints where the bead has come unstuck and water getting into walls through failed joints.
Older homes in small places like Caldecote may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Outside joints around Caldecote
Historic houses like Linford Manor (about 1.6 miles west) are a reminder that the area around Caldecote 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Tickford Park Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of St Mary Magdalene, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Façade panels
- Joints between brick and frames
- Copings & trims
Why act early in Caldecote
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. Where a wall is exposed, as many are in small places like Caldecote, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Different surfaces, different methods
Render joints
Cracks along render joints let water in behind the coat. A sound joint keeps the render dry behind.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
Looking after it afterwards
Aftercare is simple:
- Have failed joints looked at early
- Do not let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
- Show decorators and builders where the movement joints are
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. Somewhere like Caldecote needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- 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 to prepare
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
