External mastic near Bowsey Hill

Surface by surface

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.

Render joints

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

External mastic in Bowsey Hill, done properly

Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. If you have sealant that has lost its bond to the brick or render and hard, crazed mastic that has stopped moving, we can help, on concrete & block, brickwork movement joints and façade panels alike.

External sealant needs dry, clean surfaces, so work around Bowsey Hill is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.

You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

When something else is needed

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Rising or penetrating damp from elsewhere in the wall
  • Cracking across the wall rather than at a joint
  • Cutting new joints into brickwork, which is building work rather than sealant work

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Surfaces we seal

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

Bowsey Hill buildings and the weather

Historic houses like Harleyford Manor (about 3.3 miles north-east) are a reminder that the area around Bowsey Hill 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. The South East is one of the drier parts 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 St Paul's Mission Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Wargrave station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Looking after it afterwards

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

  • Clear growth from the base of walls and joints
  • Never let anyone fill a movement joint with mortar
  • Point out the joints to other trades
  • Get split or bare joints resealed while the damage is small

If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.

Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.

Why deal with it now?

Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Around Bowsey Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

What you get with us

When to call us in Bowsey Hill

Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.

Keep an eye out for any of the following:

  • Sealant that has lost its bond to the brick or render
  • Cracked joints where brick meets render or frames
  • Old sealant gone brittle and cracked
  • Weeds or debris growing in open joints

If you look after a building such as Crazies Hill CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Yes. Every job comes with our one-year guarantee.

How much does external mastic cost in Bowsey Hill?

Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.

Can a movement joint be filled with mortar?

No, not if it’s a movement joint. Pointing it stops it working. A flexible sealant is the right fill.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

How long before the joint can be used?

Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

What affects the quote in Bowsey Hill

The quote reflects the job in front of us. We take into account:

  • How easy the joints are to reach
  • The size of the job
  • The type of sealant required
  • The number of rooms or windows

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Helping us quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Where the property is
  • Photos by email, if that is easy
  • Any access issues, like height or stairs
  • What the problem is, such as mould, gaps, leaks or cracking

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.

What happens on the day

Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Bowsey Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

How to prepare

  • Mention any tricky access
  • Mention any sign-in or site rules at work premises
  • Keep pets and children clear of the area while we work
