How we handle external mastic in Clatterford End

For buildings in Clatterford End, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have old sealant gone brittle and cracked and movement joints with cracked, split or missing sealant, we can help.

Somewhere as small as Clatterford End, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.

You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or email us.

How the job changes by surface

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.

Render joints

Water behind render can lead to blown patches. Resealing the joints early keeps water out and protects the render itself.

What affects the cost of external mastic

Every job gets its own quote. This is what makes a difference:

  • Any working-time requirements on site
  • Which sealant suits the joint
  • Any mould that needs treating
  • The number of rooms or windows

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What we need to know

What to tell us when you ask for a quote:

  • Any previous sealing or DIY work
  • Roughly how big the job is
  • Photos by email, if that is easy
  • Where the job is, and your postcode

There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.

When to call us in Clatterford End

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.

The problems people normally mention when they call include:

  • Movement joints filled with mortar instead of sealant
  • Cracked joints where brick meets render or frames
  • Panel joints letting water in
  • Plants rooting in failed movement joints

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

Questions to ask before you book

  • How long to leave it before use
  • What happens if they find a problem under the old sealant
  • What guarantee comes with the work
  • Whether the sealant suits the joint

Choosing a sealant specialist

Keeping the joints in good condition

Simple care keeps the joints in good condition. Our advice:

  • Show decorators and builders where the movement joints are
  • Avoid pressure-washing directly into sealant joints
  • Walk round the building once a year and look at the joints
  • Deal with leaking gutters that soak the joints below

Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.

If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

Common questions in Clatterford End

Do you cover smaller places like Clatterford End?

What guarantee comes with external mastic in Clatterford End?

Why is there a gap in my brick wall?

Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

What external mastic looks like in Clatterford End

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.

Managing a site like The Ongar Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Clatterford End needs a little journey planning: 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. Every bit of old sealant and any mortar or debris is cut out.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. We apply the sealant, tool it and check the whole run.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Let us know about parking restrictions
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

DIY sealant or a professional job?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Leave it or put it right?

Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Around Clatterford End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
