Do you need external mastic in Mount Pleasant?
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
The problems people usually mention when they call include:
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
If you let a flat or house near Cooksbridge station, outside joints that have cracked can let damp into a rental, so check them between lets.

About our external mastic in Mount Pleasant
For buildings in Mount Pleasant, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you are dealing with failed seals between different materials and movement joints filled with mortar instead of sealant, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Mount Pleasant is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We stand behind the work with a 12-month guarantee.

Outside joints around Mount Pleasant
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Glyndebourne (about 4.1 miles south-east) are a reminder that the area around Mount Pleasant has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around St Bartholomews, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Barcombe Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How it works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work starts. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Mount Pleasant, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
To make quoting easier, please include:
- Where the job is, and your postcode
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now

Different surfaces, different methods
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Tell us what the building has when you get in touch.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.

What else we do in Mount Pleasant
Why it’s worth doing now in Mount Pleasant
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Where a wall is exposed, as many are in small places like Mount Pleasant, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
