External & façade joints in Burstow, Surrey
Problem with your movement joints in Burstow? We cut out the old, prepare the joints and apply the right sealant.
- Joints with sealant missing in places
- Gaps where render, brick and frames meet
- Old sealant gone brittle and cracked
How we handle external mastic in Burstow
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We work on render & cladding joints, concrete & block and copings & trims, and the jobs we see most are old sealant gone brittle and cracked and sealant that has lost its bond to the brick or render.
Around Burstow, 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.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Burstow, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it.

Walls and rooflines in Burstow
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Oakwood School, its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Gatwick Airport station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Leave it or put it right?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. Older cottages and farmhouses around Burstow can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What we are called out for in Burstow
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:
- Panel joints letting water in
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Joints where the bead has come unstuck
If you live in an older home near Church of St Bartholomew, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before you book
- Who turns up on the day
- How the surfaces are prepared before sealing
- What guarantee comes with the work
- Are they insured?
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Deal with leaking gutters that soak the joints below
- Wash walls gently around the sealant
- Look over the joints every year, ideally after winter
- Never let anyone fill a movement joint with mortar
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
