- Joints with sealant missing in places
How we handle external mastic in Cockpole Green
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. If you have joints pointed up with cement by mistake and sealant that has lost its bond to the brick or render, we can help, whatever the surface.
In a village or hamlet like Cockpole Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, you get the same one-year guarantee.

Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracked brickwork or render that needs a builder or plasterer
- Render that is blown, hollow or coming away
- Adding movement joints to masonry that has none
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Cockpole Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
Landlord and commercial work in Cockpole Green
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the building once a year and look at the joints
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
- Avoid pressure-washing directly into sealant joints
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

External mastic in Cockpole Green: local notes
With historic houses such as Harleyford Manor (about 2.7 miles north-east) nearby, there’s older building stock in the area around Cockpole Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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 landlords with property near Shiplake station, outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near St Paul's Mission Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Crazies Hill CofE Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Older cottages and farmhouses around Cockpole Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
