South Ockendon buildings and the weather

With historic houses such as Rainham Hall (about 4.3 miles west) nearby, there’s older building stock in the area around South Ockendon as well as newer homes. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you live in an older home near Church of St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Ockendon station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Bonnygate Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What happens on the day

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. For a job in South Ockendon, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First, the joints are inspected and the access agreed.
  2. We cut out the old mastic and rake out anything in the joint.
  3. The faces are brushed clean and primed where the product requires it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Preparing for the visit

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

Leave it or put it right?

Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In an older home around South Ockendon, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Some things make a job bigger or smaller: 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.

Quotes for external mastic in South Ockendon

Call for a quick quote. What matters most is:

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

What we need to know

Photos help, but a description is a good start. Please mention:

  • The rough size of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel
  • Where the property is

Honest limits

A few problems are outside what sealant work can do:

  • Cracked brickwork or render that needs a builder or plasterer
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Subsidence or other structural problems

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What we seal

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

How to look after the new joints

Aftercare is simple:

  • Check external joints each spring
  • Ask before painting over external sealant
  • Show decorators and builders where the movement joints are
  • Deal with leaking gutters that soak the joints below

Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.

What the job involves on each surface

Joints between dissimilar materials

Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.

Concrete and blockwork

Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
