External mastic in Shootash

What we are called out for in Shootash

Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.

Look out for these signs:

  • Weathered mastic that no longer stretches
  • Joints where the bead has come unstuck
  • Damp patches traced to an open external joint
  • Weeds or debris growing in open joints

Letting a property close to Romsey station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

What your quote should include

  • What happens if the job turns out different
  • How the joint is cleaned and prepared
  • Whether you can choose the colour
  • When the joint can take water or movement

Choosing a sealant specialist

How we handle external mastic in Shootash

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, so it bonds to the two sides only and can stretch. We work on copings & trims, brickwork movement joints and render & cladding joints, and the jobs we see most are joints with sealant missing in places and moss and dirt in joints with no sealant left.

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

Our work is backed for twelve months, in Shootash and everywhere else we cover.

Surface by surface

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.

Joints between dissimilar materials

Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.

The process

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. Somewhere like Shootash needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, the joints are inspected and the access agreed.
  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. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Keep children and pets away from the work area
  • Move anything stored near the joints

Shootash buildings and the weather

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Mottisfont Abbey (about 3 miles north) are a reminder that the area around Shootash has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

For an older house near a landmark such as Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How we quote for external mastic

Every job gets its own quote. These are the things that affect it:

  • The type of sealant required
  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • The amount of work

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.

What to tell us for a quote

Photos by email are helpful but not essential. Please mention:

  • Any access issues, like height or stairs
  • The problem you’ve noticed
  • If someone has resealed it before
  • The type of property

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or drop us an email.

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Deal with leaking gutters that soak the joints below
  • Show decorators and builders where the movement joints are
  • Don’t let climbing plants root in the sealant
  • Get split or bare joints resealed while the damage is small

Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.

Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.

Landlords, agents and businesses in Shootash

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Questions from Shootash

Do you cover smaller places like Shootash?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is Shootash in your area for external mastic?

Yes, Shootash is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.

Do you seal joints where cladding meets other materials?

Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

What does external mastic cost?

It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email and let us know what needs doing and where.

Is it messy?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Can new sealant go over the old?

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

Why act early in Shootash

Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Shootash, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
