External mastic in Bossingham

External mastic for homes and businesses in Bossingham

Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on copings & trims, concrete & block and façade panels, and the jobs we see most are leaking joints around cladding and façade panels and sealant that has lost its bond to the brick or render.

In a village or hamlet like Bossingham, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Why it’s worth doing now in Bossingham

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. In a small place like Bossingham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

DIY sealant or a professional job?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

External mastic in Bossingham: local notes

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. With historic houses such as Acrise Place (about 4.9 miles south-east) nearby, there’s older building stock in the area around Bossingham 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.

Schools such as Stelling Minnis Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St Mary include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Chartham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Bossingham is about 6 miles south of Canterbury, in Kent. Jobs in Bossingham get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. 922 places in Kent are on our list. For nearby work, see our Chelmsford page (45 miles or so).

How to look after the new joints

So the new joints stay in good condition:

  • Get split or bare joints resealed while the damage is small
  • Do not let climbing plants root in the sealant
  • Make sure movement joints are not pointed over
  • Avoid pressure-washing directly into sealant joints

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead.

Act while the splits are small. Then it’s a straightforward cut-out and reseal.

Honest limits

To be straight with you, there are a few things sealant won’t fix:

  • Movement that’s more than a sealant joint can take
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Rising or penetrating damp from elsewhere in the wall

If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

What affects the quote in Bossingham

Your quote is based on your job. We take into account:

  • The size of the job
  • Any working-time requirements on site
  • How many rooms, windows or areas are involved
  • Any mould that needs treating

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

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • What’s wrong with the joints now
  • If someone has resealed it before
  • The address or postcode of the job
  • Roughly how big the job is

We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or email us with the details.

What happens on the day

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Bossingham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us if parking is tricky
  • Keep pets and children clear of the area while we work

Getting a quote

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
