About our external mastic in Binley
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you’re dealing with sealant that has lost its bond to the brick or render and moss and dirt in joints with no sealant left, we can help.
Older homes in small places like Binley may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

The process
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. For a village or hamlet like Binley, the journey is planned in advance: 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.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

Binley buildings and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Highclere Castle (about 3.8 miles north-east) are a reminder that the area around Binley 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.
Rented homes near Whitchurch (Hampshire) station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Surface by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Leave it or put it right?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Binley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
Why us?
- Anti-fungal sanitary silicone in wet areas
- One-year guarantee on every job
- We leave the area clean and tidy
- A sealant colour to suit the surroundings
