External mastic in Sheldwich, done properly

Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. If you’re dealing with panel joints letting water in and water getting into walls through failed joints, we can put it right.

Somewhere as small as Sheldwich, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

Each job carries a 12-month guarantee, large or small.

What we do, step by step

On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Sheldwich, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. We fit closed-cell backing rod to control the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Let us know about earlier repairs to the joints
  • Tell us about any water getting in

External mastic in Sheldwich: local notes

Historic houses like Belmont House and Gardens (about 1.6 miles west) are a reminder that the area around Sheldwich has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.

If you let a flat or house near Selling station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Sheldwich Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why act early in Sheldwich

Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Where a wall is exposed, as many are in small places like Sheldwich, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

What sealant work can’t fix

To be straight with you, some problems need a different trade:

  • Failed render or damaged cladding panels
  • Walls that need new movement joints cut into them
  • Subsidence or other structural problems

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

What we seal

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

Different surfaces, different methods

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.

Your questions about external mastic in Sheldwich

Is Sheldwich within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you work for landlords with property near Selling station?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.

Will it make a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Does someone need to be in?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

What is backing rod for?

That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.

Do you do commercial work?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

What does external mastic cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

How do you reach high-level joints?

Each building is different. Send us photos and a rough idea of the height.

Can I do it myself?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Common problems we fix in Sheldwich

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, so it pulls away from the edges.

Look out for any of the following:

  • Weeds or debris growing in open joints
  • Rigid filler in a joint that should flex
  • Failed seals between different materials
  • Panel joints letting water in

In the older streets around Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Before you book anyone

  • Who does the work, and how experienced they are
  • When the joint can take water or movement
  • Which colour the sealant will be
