Outside joints around West Thurrock

With historic houses such as Rainham Hall (about 4.7 miles north-west) nearby, there’s older building stock in the area around West Thurrock 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. 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.

Rented homes near Chafford Hundred station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as West Thurrock Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

About our external mastic in West Thurrock

We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We work on joints between brick and frames, copings & trims and concrete & block, and common reasons people get in touch are rigid filler in a joint that should flex and leaking joints around cladding and façade panels.

Outbuildings, garages and conservatories around homes in places like West Thurrock add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What affects the cost of external mastic

You’ll get a clear quote before we start. It’s based on:

  • The number of rooms or windows
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out
  • How much there is to do

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

What to tell us for a quote

To make quoting easier, please include:

  • The address or postcode of the job
  • Access, such as stairs, a lift or height
  • The rough size of the job
  • Whether it has been sealed before

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

When to call us in West Thurrock

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.

If you can see any of these, it’s time to have the joints looked at:

  • Rain getting behind render or cladding at a joint
  • Failed sealant between panels on a façade
  • Moss and dirt in joints with no sealant left
  • Old sealant gone brittle and cracked

Homes close to St Clement's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

What your quote should include

  • When the joint can take water or movement
  • The length of the guarantee
  • Whether all the old sealant comes out first
  • Which colour the sealant will be

10 questions to ask before booking

Why act early in West Thurrock

Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Homes in smaller places like West Thurrock can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What you get with us

  • Any old sealant cut out fully, not covered over
  • 20+ years of sealant experience
  • Colour picked to suit the job
  • White, clear, grey or another colour, product permitting

Landlords, agents and businesses in West Thurrock

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

For anyone letting property in or around West Thurrock, several properties can be quoted together. Just tell us the addresses and what each one needs.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What we do, step by step

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. In a smaller place like West Thurrock, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. We take out the old sealant until the faces are sound.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

How to prepare

  • Tell us about any water getting in
  • Tell us about any previous sealing or DIY attempts
  • Clear the area around the work

Different surfaces, different methods

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

Brickwork movement joints

People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly.
