Need external mastic in Funtington?

Should I try it myself first?

A careful DIYer can reseal a simple joint, 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.

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

External mastic in Funtington

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We work on copings & trims, brickwork movement joints and concrete & block, and common reasons people get in touch are old sealant gone brittle and cracked and joints pointed up with cement by mistake.

Around Funtington, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.

All our work is covered by a one-year guarantee.

What sealant work can’t fix

It helps to know what we cannot do:

  • Walls that need new movement joints cut into them
  • Loose or hollow render, which needs re-rendering
  • Cracked brickwork or render that needs a builder or plasterer

If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

What we seal

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

Signs you need external mastic in Funtington

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.

Look out for these signs:

  • Weathered mastic that no longer stretches
  • Failed sealant between panels on a façade
  • Damp patches traced to an open external joint
  • Sealant that has lost its bond to the brick or render

Managing a site like Funtington Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Questions to ask before booking

  • Which colour the sealant will be
  • The length of the guarantee
  • Are they insured?
  • How much experience the applicator has

Funtington questions

Do you work for landlords with property near Nutbourne station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.

Is Funtington in your area for external mastic?

Yes. We work across London and the South East, and Funtington is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Do you seal joints where cladding meets other materials?

Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.

Should I point up the gap in my brickwork?

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

How long does external mastic last?

It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.

What should I tell you?

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

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

How to look after the new joints

After the cure time, these simple habits help:

  • Avoid pressure-washing directly into sealant joints
  • Do not let climbing plants root in the sealant
  • Act on the first splits you see
  • Never let anyone fill a movement joint with mortar

If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.

A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

External mastic in Funtington: local notes

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as West Dean House (about 4.6 miles north-east) nearby, there’s older building stock in the area around Funtington 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.

Letting a property close to Nutbourne station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near The Parish Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

The process

On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Funtington, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. Old sealant and any debris are cut and raked out.
  3. Both sides are cleaned back to sound material and primed if needed.
  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

  • Mention if the joints have been sealed before
  • For business premises, tell us about site rules or sign-in
  • Tell us about access, such as stairs, a lift or high-level joints

What happens if it’s left?

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. Older cottages and farmhouses around Funtington can have timber 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: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Why us?

  • Anti-fungal sanitary silicone in wet areas
  • A 12-month guarantee on all work
  • White, clear, grey or another colour, product permitting

Different surfaces, different methods

Cladding and façade panels

Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.

Joints between dissimilar materials

Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
