External mastic for Vauxhall homes and businesses

External mastic in Vauxhall

On houses, flats and commercial buildings across Vauxhall, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have plants rooting in failed movement joints and brick movement joints where the sealant has split, we can put it right, whatever the surface.

Outside work in London starts with access: side passages, upper floors and where to park. For a home in Vauxhall, tell us how high the joints are and how to reach the back of the building.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

When it isn’t the sealant

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

  • Cracking across the wall rather than at a joint
  • Walls that need new movement joints cut into them
  • Structural movement, which needs a surveyor or engineer

If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

Where we work in Vauxhall

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

Why it’s worth doing now in Vauxhall

Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. In a flat in Vauxhall, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.

Walls and rooflines in Vauxhall

London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. 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.

If you live in an older home near St Peter's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Vauxhall Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Vauxhall is about 1 mile south-west of London, in Greater London.

FAQs for Vauxhall

Do you cover Vauxhall for external mastic?

Yes. Our work covers London and the South East, and Vauxhall is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

Can parking be tricky for a visit in Vauxhall?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Where are you based?

Our base is Crawley. Our area covers South East England, London and Scotland.

Is the work guaranteed?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

What colours does the sealant come in?

The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.

How long should I leave it?

Different products cure at different speeds, so follow the cure time we give you when we finish.

Are you fully insured?

Yes. We’re fully insured for domestic and commercial work.

What do you put in the joint?

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Keep movement joints as flexible joints, not mortar
  • Keep soil, plants and ivy away from the joints
  • Look over the joints every year, ideally after winter
  • Leave the joints unpainted unless we’ve said otherwise

Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.

Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.

How it works

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes anything from a few hours to several days, depending on the building for a typical job. In Vauxhall, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  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. Joint faces are cleaned back and primed if the sealant needs it.
  4. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Plan for the work area to be out of bounds to pets and children
  • Mention if the joints have been sealed before

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Surface by surface

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.

Joints between dissimilar materials

Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.

Signs you need external mastic in Vauxhall

A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.

Signs it’s time to call us include:

  • Cracked joints where brick meets render or frames
  • Brick movement joints where the sealant has split
  • Sealant pulling away from one side of the joint
  • Rain getting behind render or cladding at a joint

Vauxhall is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
