- Movement that’s more than a sealant joint can take
- Damp that isn’t coming from the joint
- Loose or hollow render, which needs re-rendering

External mastic in Weavers Down, done properly
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on façade panels, render & cladding joints and concrete & block, and common reasons people get in touch are plants rooting in failed movement joints and sealant that has lost its bond to the brick or render.
Around Weavers Down, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What we are called out for in Weavers Down
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The most common problems we see are:
- Moss and dirt in joints with no sealant left
- Movement joints filled with mortar instead of sealant
- Sealant pulling away from one side of the joint
- Weathered mastic that no longer stretches
Rented homes near Liphook station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

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.
For site and facilities teams at buildings such as Liphook Church of England Controlled Junior School, larger buildings have long runs of movement joint that eventually need resealing.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Avoid pressure-washing directly into sealant joints
- Act on the first splits you see
- Do not let climbing plants root in the sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building in most cases. For a village or hamlet like Weavers Down, 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, 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.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
