How we handle external mastic in West Lavington

A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on copings & trims, concrete & block and joints between brick and frames, and the jobs we see most are movement joints filled with mortar instead of sealant and moss and dirt in joints with no sealant left.

Outside joints can only be sealed when they’re dry, so work in West Lavington is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?

A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around West Lavington can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Make sure movement joints are not pointed over
  • Wash walls gently around the sealant
  • Check external joints each spring
  • Get split or bare joints resealed while the damage is small

Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.

Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.

How the visit works

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like West Lavington, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by checking each joint, agreeing the ones to redo and how we will reach them.
  2. The old mastic and anything lodged in the joint is removed.
  3. Both sides are cleaned back to sound material and primed if needed.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks

Related advice

What the job involves on each surface

Cladding and façade panels

Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.

Copings and trims

A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.

How we quote for external mastic

For a quick quote, just ask. The main things that affect it are:

  • The product the joint needs
  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • How many rooms, windows or areas are involved

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

When you contact us, these details help:

Walls and rooflines in West Lavington

With historic houses such as Cowdray House (about 0.6 miles north) nearby, there’s older building stock in the area around West Lavington as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For an older house near a landmark such as The Parish Church of St Mary Magdalene, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

West Lavington: your questions answered

Is there a guarantee on external mastic in West Lavington?

Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Is West Lavington within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is it messy?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

What information do you need?

A short description and the location. If we need more, we will ask.

Do you work at height?

It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we will confirm what access is needed.

How much does external mastic cost in West Lavington?

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email and let us know what needs doing and where.

Will the old sealant be removed?

Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

What’s an expansion joint in brickwork?

A vertical gap in a long brick wall is usually a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.

Common problems we fix in West Lavington

Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.

The problems people normally mention when they call are:

  • Moss and dirt in joints with no sealant left
  • Joints where the bead has come unstuck
  • Joints pointed up with cement by mistake
  • Gaps where render, brick and frames meet

For site and facilities teams at buildings such as Midhurst CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What to look for in a quote

  • How the joint is cleaned and prepared
  • Is the old sealant removed completely?
  • How long to leave it before use
  • What happens if they find a problem under the old sealant

What sealant work cannot fix

Sealant is not the answer to every problem, and we’ll tell you before we start. It will not solve:

  • Cracking across the wall rather than at a joint
  • Damp that is not coming from the joint
  • Failed render or damaged cladding panels

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
