About our external mastic in Tangley

Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. Common call-outs are for movement joints with cracked, split or missing sealant and panel joints letting water in, across joints between brick and frames, brickwork movement joints and concrete & block.

Around Tangley, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Tangley buildings and the weather

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.

If you live in an older home near Church of St Thomas of Canterbury, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Different surfaces, different methods

Copings and trims

Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.

Brickwork movement joints

Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.

Landlords, agents and businesses in Tangley

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.

If you manage several properties in or around Tangley, several properties can go on one quote. Just tell us the addresses and what each one needs.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We cut it out and start again.

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 doesn’t work out, we can still put it right.

What happens if it’s left?

Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. In a small place like Tangley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Aftercare tips

After the cure time, these simple habits help:

  • Do not let climbing plants root in the sealant
  • Get split or bare joints resealed while the damage is small
  • Look over the joints every year, ideally after winter
  • Check the sealant is paintable before painting near it

Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.

Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.

What we do, step by step

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the building. In a small place like Tangley, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we look over the joints with you, agree which to renew and talk through access.
  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. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Before we arrive

  • Tell us about any water getting in
  • Clear items away from the joints we’re working on
  • Let us know about stairs, lifts or work at height

Advice

What we are called out for in Tangley

Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.

Any of these means the joints need attention:

  • Weeds or debris growing in open joints
  • Sealant that has lost its bond to the brick or render
  • Failed seals between different materials
  • Weathered mastic that no longer stretches

If you let a flat or house near Andover station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Before you book anyone

  • Whether all the old sealant comes out first
  • What happens if they find a problem under the old sealant
  • Which colour the sealant will be
  • How long to leave it before use
