Trusted external mastic in Green End

How the visit works

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere like Green End needs a little journey planning: 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. Each joint is checked and the colour of the new sealant agreed.
  2. We take out the old sealant until the faces are sound.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Getting ready for the visit

  • Mention any tricky access
  • Mention any leaks or damp you’ve noticed
  • Keep pets and children clear of the area while we work

How we handle external mastic in Green End

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 are dealing with movement joints with cracked, split or missing sealant and moss and dirt in joints with no sealant left, we can put it right, whatever the surface.

External sealant needs dry, clean surfaces, so work around Green End is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.

Big or small, you get the same 12-month guarantee in Green End and across Buckinghamshire.

What the job involves on each surface

Cladding and façade panels

Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.

Joints between dissimilar materials

Wherever two materials meet, they move differently. A flexible sealant bridges the two.

What affects the quote in Green End

Jobs vary more than people expect. The main factors:

  • The amount of work
  • How many areas need sealing
  • Access and height
  • The old material and how stubborn it is

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

What we need to know

To make quoting easier, let us know:

  • How many joints, rooms or windows are involved
  • Access, such as stairs, a lift or height
  • A few pictures by email, if you can
  • Where the job is, and your postcode

For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Do you need external mastic in Green End?

Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.

If you can see any of these, it’s time to have the joints looked at:

  • Water getting into walls through failed joints
  • Joints where the bead has come unstuck
  • Rigid filler in a joint that should flex
  • Failed seals between different materials

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

What to look for in a quote

  • Which sealant they’ll use, and why
  • What the quote includes, VAT included or not
  • What the cure time is
  • Whether they’re fully insured

How to choose a mastic man

Green End buildings and the weather

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. Historic houses like West Wycombe Park House (about 1.9 miles south-east) are a reminder that the area around Green End has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

West Wycombe Park House, about 1.9 miles south-east, is one of the historic houses in the wider area around Green End. For site and facilities teams at buildings such as The Mary Towerton School At Studley Green, its movement joints, gutters and trims need looking after like any other building’s.

When it isn’t the sealant

In fairness, there are a few things sealant will not fix:

  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Cracked brickwork or render that needs a builder or plasterer
  • Failed render or damaged cladding panels

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.

Joints and surfaces we work on

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