How we handle external mastic in Abinger Hammer

For buildings in Abinger Hammer, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Typical jobs include rain getting behind render or cladding at a joint and plants rooting in failed movement joints, across copings & trims, brickwork movement joints and concrete & block.

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

We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

How the job changes by surface

Brickwork movement joints

Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly where it can be done safely.

Copings and trims

Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.

Why deal with it now?

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 pays to do it properly once. In a small place like Abinger Hammer, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Why book with us

  • Old sealant always removed completely
  • Every job guaranteed for a year

How to look after the new joints

Simple care keeps the joints in good condition. Our advice:

  • Wash walls gently around the sealant
  • Tell anyone working on the walls about the movement joints
  • Keep soil, plants and ivy away from the joints
  • Look over the joints every year, ideally after winter

Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.

Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

What affects the cost of external mastic

Call for a quick quote. What matters most is:

  • How much old sealant there is and how hard it is to remove
  • Which sealant suits the joint
  • How many rooms, windows or areas are involved
  • Any working-time requirements on site

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.

Do you guarantee your work?

Yes, always. There’s a 12-month guarantee on every job, large or small.

Will the new joint stand out?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint doesn’t draw the eye.

Is it OK to fill a movement joint with cement?

No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We will reseal it with a flexible sealant.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

What happens on the day

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Abinger Hammer, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. Old sealant and any debris are cut and raked out.
  3. Both sides are cleaned back to sound material and primed if needed.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints

What we cannot put right

New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:

  • Loose or hollow render, which needs re-rendering
  • Cracking across the wall rather than at a joint
  • Damp that isn’t coming from the joint

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

What we seal

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