Outside joints around East Clandon

With historic houses such as Hatchlands Park (about 0.5 miles north-east) nearby, there’s older building stock in the area around East Clandon as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.

If you let a flat or house near Clandon station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St Thomas of Canterbury, older walls, gutters and the joints where extensions meet them need a flexible sealant.

About our external mastic in East Clandon

Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. We work on copings & trims, render & cladding joints and concrete & block, and common reasons people get in touch are brick movement joints where the sealant has split and weathered mastic that no longer stretches.

Older homes in small places like East Clandon may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

Whatever the size of the job, it’s backed by our one-year guarantee in East Clandon and across Surrey.

What sealant work cannot fix

Some problems need a builder, plumber or other trade rather than us:

  • Cracks in the bricks or render themselves, away from the joints
  • Subsidence or other structural problems
  • Rising or penetrating damp from elsewhere in the wall

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Where we work in East Clandon

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

Common problems we fix in East Clandon

Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.

Most people get in touch when they notice something like this:

  • Damp patches traced to an open external joint
  • Joints with sealant missing in places
  • Plants rooting in failed movement joints
  • Old sealant gone brittle and cracked

Schools such as Clandon CofE Aided Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

How to choose a mastic man

Work for landlords, hotels and businesses

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured for the work.

The process

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. Somewhere as small as East Clandon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at every joint and agree a colour to suit the wall.
  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. We prime the faces where required.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Before we arrive

  • Let us know about parking restrictions
  • Try not to wet indoor joints just before the visit
  • Move anything stored near the joints

What the job involves on each surface

Render joints

The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Cladding and façade panels

Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.

Questions from East Clandon

Do you cover smaller places like East Clandon?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do external mastic in East Clandon?

Yes. Our work covers London and the South East, and East Clandon is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

Is it OK to seal over old sealant?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

What colours does the sealant come in?

We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.

What is a movement joint?

Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Is there a guarantee?

Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

What affects the quote in East Clandon

Call for a quick quote. What matters most is:

  • The size of the job
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • Access and height

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

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

  • The rough size of the job
  • Where the job is, and your postcode
  • Access, such as stairs, a lift or height
  • Pictures of the joints, sent by email

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or email us.

Can I do it myself?

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
