How we handle external mastic in Studdal

Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We are often asked to deal with panel joints letting water in and cracked joints where brick meets render or frames, across joints between brick and frames, copings & trims and render & cladding joints.

Older homes in small places like Studdal may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.

Whatever the size of the job, it’s backed by our 12-month guarantee.

Leave it or put it right?

Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Where a wall is exposed, as many are in small places like Studdal, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

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 does not work out, we can still put it right.

Walls and rooflines in Studdal

With historic houses such as Walmer Castle (about 4 miles east) nearby, there’s older building stock in the area around Studdal as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.

For landlords with property near Martin Mill station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Signs you need external mastic in Studdal

The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.

Any of these means the joints need attention:

  • Joints pointed up with cement by mistake
  • Leaking joints around cladding and façade panels
  • Hard, crazed mastic that has stopped moving
  • Sealant pulling away from one side of the joint

For an older house near a landmark such as East Studdal Church Hall, an extension built onto an older house moves differently, and the joint between them takes the strain.

Questions to ask before you book

  • How the surfaces are prepared before sealing
  • Whether they’re fully insured
  • Which colour the sealant will be
  • Who turns up on the day

10 questions to ask before you book

Different surfaces, different methods

Brickwork movement joints

Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod coloured to suit the wall.

Concrete and blockwork

The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before the bead.

What we do, step by step

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Studdal, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Preparing for the visit

  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit
