How we handle external mastic in Bocking Churchstreet

A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. We work on brickwork movement joints, concrete & block and copings & trims, and the jobs we see most are cracked joints where brick meets render or frames and rigid filler in a joint that should flex.

In and around Bocking Churchstreet, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.

Whatever the size of the job, it’s backed by our 12-month guarantee.

Bocking Churchstreet buildings and the weather

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Managing a site like Bocking Church Street Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What the job involves on each surface

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.

Joints between dissimilar materials

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

What affects the cost of external mastic

Call for a quick quote. What matters most is:

  • The number and length of the joints
  • How many areas need sealing
  • Mould in or behind the old joints
  • Which sealant suits the joint

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Helping us quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

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

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

What happens if it’s left?

It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. In a smaller place like Bocking Churchstreet, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Why choose Mr Mastic in Bocking Churchstreet

  • Old sealant always removed completely

  • Neat joints and a tidy finish

Read what affects the cost or our reviews.

Looking after it afterwards

So the new joints stay in good condition:

  • Keep soil, plants and ivy away from the joints
  • Make sure movement joints are not pointed over
  • Fix overflowing gutters above sealed joints
  • Keep high-pressure jets off the joints

Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

What we do, step by step

The work is kept neat and contained to the area we’re working on. The job usually takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. For a job in Bocking Churchstreet, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We look at every joint and agree a colour to suit the wall.
  2. Failed sealant is removed back to clean, sound faces.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

Before we arrive

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • Mention any tricky access

Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Is Bocking Churchstreet within the area you cover?

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

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

How long should I leave it?

Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status.

Is it OK to seal over old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Do you guarantee your work?

Yes. Each job is guaranteed for twelve months, wherever you are.

Signs you need external mastic in Bocking Churchstreet

UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.

Any of these means the joints need attention:

  • Weathered mastic that no longer stretches
  • Sealant that has lost its bond to the brick or render
  • Failed sealant between panels on a façade
  • Joints with sealant missing in places

If you let a flat or house near Braintree station, outside joints that have cracked can let damp into a rental, so check them between lets.
