About our external mastic in Well Head

A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you’re dealing with old sealant gone brittle and cracked and sealant pulling away from one side of the joint, we can help.

Somewhere as small as Well Head, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

We stand behind the work with a one-year guarantee.

What we’re called out for in Well Head

Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.

The problems people usually mention when they call are:

  • Panel joints letting water in
  • Rain getting behind render or cladding at a joint
  • Weathered mastic that no longer stretches
  • Weeds or debris growing in open joints

If you live in an older home near St Mary's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Our hiring checklist

Why act early in Well Head

Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In a small place like Well Head, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How the visit works

At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere as small as Well Head, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, the joints are inspected and the access agreed.
  2. We cut out the old mastic and rake out anything in the joint.
  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.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Honest limits

We won’t take on work that will not last, so here’s what sealant can’t put right:

  • Cracks in the bricks or render themselves, away from the joints
  • Rising or penetrating damp from elsewhere in the wall
  • Movement that is more than a sealant joint can take

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

Common questions in Well Head

Can you do external mastic in Well Head?

Yes. Our work covers London and the South East, and Well Head is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.

Do you cover smaller places like Well Head?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Can you work on commercial sites?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

When will the joints need doing again?

That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and reseal when it splits.

Do you remove the old sealant?

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

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 pictures.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Keeping the joints in good condition

Aftercare is simple:

  • Deal with leaking gutters that soak the joints below
  • Walk round the building once a year and look at the joints
  • Get split or bare joints resealed while the damage is small
  • Keep movement joints as flexible joints, not mortar

Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted.

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.

Different surfaces, different methods

Joints between dissimilar materials

Different materials may need different primers. We prepare both faces so the sealant bonds properly.

Brickwork movement joints

Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.

Outside joints around Well Head

With historic houses such as Goodnestone Park (about 1.6 miles south) nearby, there’s older building stock in the area around Well Head 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For landlords with property near Adisham station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Wingham Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
