External mastic in Redford: local notes

London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Cowdray House (about 3.4 miles south-east) nearby, there’s older building stock in the area around Redford as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

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

External mastic in Redford

External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. We are often asked to deal with old sealant gone brittle and cracked and rain getting behind render or cladding at a joint, across façade panels, render & cladding joints and concrete & block.

Around Redford, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.

Whatever the size of the job, you get the same 12-month guarantee in Redford and across West Sussex.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Never let anyone fill a movement joint with mortar
  • Keep water from gutters off the wall
  • Check the sealant is paintable before painting near it
  • Get split or bare joints resealed while the damage is small

Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.

A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

Surface by surface

Concrete and blockwork

Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it.

Joints between dissimilar materials

Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.

When something else is needed

Before you book, it’s worth knowing the limits:

  • Cracked brickwork or render that needs a builder or plasterer
  • Damp that isn’t coming from the joint
  • Loose or hollow render, which needs re-rendering

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

Surfaces we seal

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

Common problems we fix in Redford

Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.

Most people get in touch after spotting something like this:

  • Sealant that has lost its bond to the brick or render
  • Rigid filler in a joint that should flex
  • Brick movement joints where the sealant has split
  • Moss and dirt in joints with no sealant left

If you live in an older home near Church of St Luke, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Before booking anyone

  • How long the guarantee is
  • Which sealant they’ll use, and why
  • What happens if they find a problem under the old sealant
  • Whether they seal over old material or remove it

Our hiring checklist

Redford questions

Do you cover Redford for external mastic?

Yes, Redford is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.

Is Redford within the area you cover?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in.

I rent my home. Can I book you?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Can you seal over the old sealant?

No, because it fails. The old sealant always comes out first.

What’s an expansion joint in brickwork?

It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done.

Do you work for letting agents?

Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Redford.

What affects the cost of external mastic

We do not publish a price list, because no two jobs are the same. What we look at:

  • How easy the joints are to reach
  • Which sealant suits the joint
  • The old material and how stubborn it is
  • The number and length of the joints

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What to tell us for a quote

When you contact us, these details help:

  • Whether it has been sealed before
  • Access, such as stairs, a lift or height
  • The address or postcode of the job
  • How many joints, rooms or windows are involved

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or email us.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

What we do, step by step

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Redford, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at every joint and agree a colour to suit the wall.
  2. Failed sealant is removed back to clean, sound faces.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

How to prepare

  • Move anything stored near the joints
  • Mention any sign-in or site rules at work premises
  • Tell us about any previous sealing or DIY attempts
