External mastic for West Ashling homes and businesses

How we handle external mastic in West Ashling

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement. We work on concrete & block, façade panels and joints between brick and frames, and the jobs we see most are moss and dirt in joints with no sealant left and sealant pulling away from one side of the joint.

Somewhere as small as West Ashling, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

Your job is guaranteed for a year, as with all our work.

What happens on the day

We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. For a village or hamlet like West Ashling, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Preparing for the visit

  • Mention any tricky access
  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we are working on

Advice

FAQs for West Ashling

Is West Ashling within the area you cover?

Yes, West Ashling is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you work for landlords with property near Bosham station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Do I need to be at home?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Why do you put foam in the joint first?

Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us, and we are fully insured.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

How much does external mastic cost in West Ashling?

Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email and let us know what needs doing and where.

When to call us in West Ashling

The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.

Common reasons people contact us are:

  • Gaps where render, brick and frames meet
  • Leaking joints around cladding and façade panels
  • Joints with sealant missing in places
  • Sealant that has lost its bond to the brick or render

Managing a site like Funtington Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Our hiring checklist

What the job involves on each surface

Cladding and façade panels

If the façade has a specified sealant, that’s what we use, or one the system allows. Send us any details you have about the façade.

Copings and trims

Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.

Walls and rooflines in West Ashling

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as West Dean House (about 4.6 miles north-east) nearby, there’s older building stock in the area around West Ashling as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

For an older house near a landmark such as The Parish Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Bosham station, split movement joints are easy to miss on a rental until damp shows inside.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Cracking across the wall rather than at a joint
  • Adding movement joints to masonry that has none
  • Loose or hollow render, which needs re-rendering

If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Surfaces we seal

  • Copings & trims
  • Brickwork movement joints
  • Joints between brick and frames
  • Render & cladding joints
  • Concrete & block
  • Façade panels

Aftercare tips

A little care helps the new joints last. We recommend:

  • Act on the first splits you see
  • Point out the joints to other trades
  • Walk round the building once a year and look at the joints
  • Check the sealant is paintable before painting near it

Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.

Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.

Leave it or put it right?

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. In a small place like West Ashling, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
