External & façade joints in Micheldever, Hampshire
Movement joints in Micheldever need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Sealant that has lost its bond to the brick or render
- Panel joints letting water in
- Moss and dirt in joints with no sealant left
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep water from gutters off the wall
- Ask before painting over external sealant
- Avoid pressure-washing directly into sealant joints
- Point out the joints to other trades
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
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.
About our external mastic in Micheldever
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. Common call-outs are for plants rooting in failed movement joints and damp patches traced to an open external joint, across concrete & block, façade panels and brickwork movement joints.
Older homes in small places like Micheldever may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Why it’s worth doing now in Micheldever
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Micheldever, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.
Common problems we fix in Micheldever
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we are asked about most:
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
- Joints pointed up with cement by mistake
Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
