External mastic for Woodmancote homes and businesses

How we handle external mastic in Woodmancote

Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on brickwork movement joints, render & cladding joints and façade panels, and the jobs we see most are panel joints letting water in and failed seals between different materials.

Older homes in small places like Woodmancote may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.

All of our work is guaranteed for twelve months.

What the job involves on each surface

Render joints

Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.

Joints between dissimilar materials

Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.

Outside joints around Woodmancote

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.

Letting a property close to Hassocks station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

How it works

The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Woodmancote needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

What happens if it’s left?

Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. Older cottages and farmhouses around Woodmancote can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we’ll talk you through it.

Questions from Woodmancote

I let a flat near Hassocks station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.

Do you cover smaller places like Woodmancote?

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

Are you fully insured?

Yes, we’re fully insured for every job we do.

What does external mastic cost?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.

Is there any odour?

That depends on the sealant. Some smell for a while, some hardly at all.

Are you ARBOMaster approved?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

We also work for property managers and facilities teams in Woodmancote and across West Sussex. We can quote a run of properties together, and we’re fully insured.

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

Do you need external mastic in Woodmancote?

Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.

The problems people normally mention when they call include:

  • Sealant that has lost its bond to the brick or render
  • Old sealant gone brittle and cracked
  • Panel joints letting water in
  • Water getting into walls through failed joints

In the older streets around The Parish Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Questions to ask before you book

  • What the cure time is
  • What happens if they find a problem under the old sealant
  • How much experience the applicator has
  • Whether you can choose the colour

Honest limits

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

  • Failed render or damaged cladding panels
  • Adding movement joints to masonry that has none
  • Cracked brickwork or render that needs a builder or plasterer

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

How we quote for external mastic

There’s no set price list, because no two jobs are the same. What we look at:

  • The size of the job
  • Working hours on commercial sites
  • The number of rooms or windows
  • The product the joint needs

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

What we need to know

When you call or email, it’s useful to know:

  • The problem you’ve noticed
  • Roughly how big the job is
  • A few pictures by email, if you can
  • Where the property is

We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or email us with the details, and pictures are welcome.
