External mastic in East Worldham

External mastic in East Worldham

For buildings in East Worldham, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have sealant pulling away from one side of the joint and brick movement joints where the sealant has split, we can help, whatever the surface.

In a village or hamlet like East Worldham, older cottages and farm buildings often stand in the open, 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.

All our work is covered by a one-year guarantee.

How it works

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like East Worldham needs a little journey planning: let us know about lanes, gates and parking. 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. We clean both faces of the joint and prime them where the product calls for it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Common questions in East Worldham

Will you come out to East Worldham?

Yes. East Worldham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do external mastic in East Worldham?

Yes, East Worldham is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.

What is backing rod for?

Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Is the work guaranteed?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

What should I tell you?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.

What colours does the sealant come in?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it does not stand out.

How the job changes by surface

Joints between dissimilar materials

Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.

Brickwork movement joints

Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.

East Worldham buildings and the weather

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.

Rented homes near Alton station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Eggar's School, its movement joints, gutters and trims need looking after like any other building’s.

How we quote for external mastic

Some jobs are bigger than they look, and some smaller. The main factors:

  • Access and height
  • How many rooms, windows or areas are involved
  • Which sealant suits the joint
  • Working hours on commercial sites

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What to tell us for a quote

To make quoting easier, please include:

  • A few pictures by email, if you can
  • What’s wrong with the joints now
  • Whether it’s a home or a business
  • How we’d reach the joints

We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job.

Common problems we fix in East Worldham

Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.

Most people get in touch after spotting something like this:

  • Rain getting behind render or cladding at a joint
  • Weathered mastic that no longer stretches
  • Panel joints letting water in
  • Brick movement joints where the sealant has split

If you live in an older home near Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Before booking anyone

  • How long to leave it before use
  • Is VAT in the price?
  • How the joint is cleaned and prepared
  • What product goes in the joint

10 questions to ask before you book

Aftercare tips

After the cure time, these simple habits help:

  • Leave the joints unpainted unless we’ve said otherwise
  • Clear growth from the base of walls and joints
  • Keep movement joints as flexible joints, not mortar
  • Tell anyone working on the walls about the movement joints

Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.

A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
