External mastic in Appley

External mastic for homes and businesses in Appley

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. If you are dealing with leaking joints around cladding and façade panels and damp patches traced to an open external joint, we can put it right.

In a smaller place like Appley, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.

All our work is covered by our 12-month guarantee, wherever you are in the Isle of Wight.

Walls and rooflines in Appley

Appley is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Nunwell House (about 2.9 miles south) nearby, there’s older building stock in the area around Appley 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 live in an older home near St John's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Oakfield Church of England Aided Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Appley is about 1 mile east of Ryde, in the Isle of Wight. Appley gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Our area takes in 125 places across the Isle of Wight. Our Portsmouth page covers work nearby, about 6 miles away.

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Have failed joints looked at early
  • Wash walls gently around the sealant
  • Walk round the building once a year and look at the joints
  • Check the sealant is paintable before painting near it

Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.

Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.

What the job involves on each surface

Joints between dissimilar materials

Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.

Render joints

Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.

Why act early in Appley

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In an older home around Appley, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before we start.

Do you need external mastic in Appley?

A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.

Signs it’s time to call us include:

  • Movement joints filled with mortar instead of sealant
  • Brick movement joints where the sealant has split
  • Leaking joints around cladding and façade panels
  • Sealant that has lost its bond to the brick or render

If you let a flat or house near Ryde St Johns Road station, split movement joints are easy to miss on a rental until damp shows inside.

Choosing a sealant specialist

Appley: your questions answered

Can you help a landlord with a rental near Ryde St Johns Road station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.

Is external mastic in a coastal place like Appley any different?

Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.

Can you seal joints between render and window frames?

Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.

How long does external mastic last?

It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.

Are you an approved applicator?

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

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

Is it OK to fill a movement joint with cement?

No. Cement or mortar can’t stretch and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.

Where are you based?

We are based in Crawley, and we work across South East England, London and Scotland.

What happens on the day

We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. In a smaller place like Appley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. We cut out the failed sealant and rake out any dirt or growth.
  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. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Before we arrive

  • Clear the area around the work
  • For indoor joints, keep the area dry beforehand if you can
  • Mention any sign-in or site rules at work premises

Advice

When it isn’t the sealant

We’d rather tell you now than do work that will not last, so these are the limits:

  • Movement that’s more than a sealant joint can take
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Cracking across the wall rather than at a joint

Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

What we seal

  • Copings & trims
  • Façade panels
  • Render & cladding joints
