Trusted external mastic in Bramber

About our external mastic in Bramber

We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it. We work on copings & trims, brickwork movement joints and render & cladding joints, and common reasons people get in touch are hard, crazed mastic that has stopped moving and failed sealant between panels on a façade.

Outside joints can only be sealed when they’re dry, so work in Bramber is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

How the job changes by surface

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.

Joints between dissimilar materials

Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.

What affects the cost of external mastic

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

  • The number and length of the joints
  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • Access and height

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What we need to know

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

  • Photos by email, if that is easy
  • If it’s domestic, commercial or a hotel
  • Whether it has been sealed before
  • What’s wrong with the joints now

We do not publish a price list, because every job is different. Instead, we give you a clear quote for your job. To arrange one, call 0345 464 0079 or drop us an email.

What we are called out for in Bramber

Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.

It’s worth asking for a quote if you see:

  • Rigid filler in a joint that should flex
  • Cracked joints where brick meets render or frames
  • Panel joints letting water in
  • Weathered mastic that no longer stretches

Homes close to The Parish Church of St Nicholas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What to look for in a quote

  • The length of the guarantee
  • How long to leave it before use
  • Which colour the sealant will be
  • How much experience the applicator has

10 questions to ask before you book

Leave it or put it right?

A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. Around Bramber, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

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’ll know the price before we begin.

What you get with us

  • We leave the area clean and tidy

Honest limits

We will not take on work that won’t last, so these are the limits:

  • Cracking across the wall rather than at a joint
  • Subsidence or other structural problems
  • Cutting new joints into brickwork, which is building work rather than sealant work

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

What we seal

  • Façade panels

Bramber questions

Is Bramber within the area you cover?

Yes, Bramber is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you do external mastic in Bramber?

Yes, Bramber is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Do you hold any approvals?

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

Can you reach joints on upper floors?

It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.

Do you seal joints where cladding meets other materials?

Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.

What information do you need?

Let us know what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Will the old sealant be removed?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Bramber 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.

For site and facilities teams at buildings such as Upper Beeding Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What happens on the day

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on the building. Somewhere as small as Bramber, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by walking round the building and agreeing the joints and the access.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. The faces are brushed clean and primed where the product requires it.
  4. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.
