About our external mastic in Finstock

A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with damp patches traced to an open external joint and joints pointed up with cement by mistake, we can help, whatever the surface.

Somewhere as small as Finstock, 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.

Every job comes with a one-year guarantee, wherever you are in Oxfordshire.

Should I try it myself first?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Outside joints around Finstock

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Minster Lovell Hall (about 3.8 miles south-west) are a reminder that the area around Finstock has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

For site and facilities teams at buildings such as Finstock Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. Homes close to Church of the Holy Trinity include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Why deal with it now?

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. A flexible sealant over backing rod is what the joint needs. In a small place like Finstock, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Landlords, agents and businesses in Finstock

In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.

Aftercare tips

After the cure time, these simple habits help:

  • Check external joints each spring
  • Keep high-pressure jets off the joints
  • Keep water from gutters off the wall
  • Show decorators and builders where the movement joints are

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

If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.

How the visit works

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on the building. For a village or hamlet like Finstock, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any water getting in
  • Move anything stored near the joints

Common problems we fix in Finstock

Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.

People generally contact us when they notice something like this:

  • Movement joints with cracked, split or missing sealant
  • Weathered mastic that no longer stretches
  • Rain getting behind render or cladding at a joint
  • Failed sealant between panels on a façade

Letting a property close to Finstock station? Then split movement joints are easy to miss on a rental until damp shows inside.

What to look for in a quote

  • Whether the sealant suits the joint
