External mastic in West Ealing

Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. If you have panel joints letting water in and plants rooting in failed movement joints, we can put it right, whatever the surface.

Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.

We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Why it’s worth doing now in West Ealing

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in West Ealing, the repair is bigger than the sealant job would have been.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

How we quote for external mastic

Jobs vary more than people expect. The main factors:

  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove
  • The number and length of the joints
  • The type of sealant required

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business
  • Whether it has been sealed before
  • Pictures of the joints, sent by email

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Surface by surface

Joints between dissimilar materials

Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.

Copings and trims

Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a job in West Ealing, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. The old mastic and anything lodged in the joint is removed.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • For business premises, tell us about site rules or sign-in
  • Keep pets and children clear of the area while we work

  • Render that’s blown, hollow or coming away
  • Movement that is more than a sealant joint can take

What external mastic looks like in West Ealing

Historic houses like Pitzhanger Manor (about 1.4 miles east) are a reminder that the area around West Ealing 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. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.

For an older house near a landmark such as St Mary's Cathedral, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Hanwell station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. As a London address, West Ealing can be tricky for parking: let us know about parking bays, permits or a driveway.

Your questions about external mastic in West Ealing

Can parking be tricky for a visit in West Ealing?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Is West Ealing in your area for external mastic?

Yes, West Ealing is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.

How long does the job take?

Typically it takes anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we’ll say how long yours will take.

Should I point up the gap in my brickwork?

No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

What is backing rod for?

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

Do you work for landlords and businesses?

Yes, we do. We work in homes, commercial premises and hotels.

Can you do several jobs on one visit?

Yes, we can. More than one area can go on one quote.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Aftercare tips

After the cure time, these simple habits help:

  • Clear growth from the base of walls and joints
  • Look over the joints every year, ideally after winter
  • Check the sealant is paintable before painting near it
  • Never let anyone fill a movement joint with mortar

Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.

Small splits are the time to act. At that stage it’s a simple cut out and reseal.
