Do you need external mastic in Botolph Claydon?
If plants are growing out of a joint, the sealant has normally failed or was never there. Roots and dirt hold water against the wall.
Signs it’s time to call us include:
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- How hidden problems are handled
- When the joint can take water or movement
- How the surfaces are prepared before sealing
- Which colour the sealant will be
External mastic in Botolph Claydon
A movement joint is only as good as its depth. 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. If you’re dealing with cracked joints where brick meets render or frames and weathered mastic that no longer stretches, we can put it right, whatever the surface.
Older homes in small places like Botolph Claydon 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.
Big or small, it’s backed by our 12-month guarantee in Botolph Claydon and across Buckinghamshire.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Fix overflowing gutters above sealed joints
- Check the sealant is paintable before painting near it
- Avoid pressure-washing directly into sealant joints
- Show decorators and builders where the movement joints are
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. Somewhere as small as Botolph Claydon, 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.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

Walls and rooflines in Botolph Claydon
With historic houses such as Claydon House (about 1 mile west) nearby, there’s older building stock in the area around Botolph Claydon 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. 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.
For site and facilities teams at buildings such as East Claydon Church of England School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why it’s worth doing now in Botolph Claydon
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Older cottages and farmhouses around Botolph Claydon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.

Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
