Trusted external mastic in Kirdford

External mastic in Kirdford, done properly

On houses, flats and commercial buildings across Kirdford, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on façade panels, joints between brick and frames and copings & trims, and people most often call us about water getting into walls through failed joints and hard, crazed mastic that has stopped moving.

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

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Work for landlords, hotels and businesses

We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

If you manage several properties in or around Kirdford, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.

When it is not the sealant

Sealant is not the answer to every problem, and we will tell you before any work starts. Sealant will not put right:

  • Rising or penetrating damp from elsewhere in the wall
  • Walls that need new movement joints cut into them
  • Structural movement, which needs a surveyor or engineer

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Surfaces we seal

  • Façade panels
  • Render & cladding joints

Kirdford: your questions answered

Do you work for landlords with property near Billingshurst station?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

Do you cover smaller places like Kirdford?

Yes, Kirdford is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Is there a guarantee?

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

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

Are you insured?

Yes. We are fully insured.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Kirdford buildings and the weather

Historic houses like Petworth House (about 4.1 miles south-west) are a reminder that the area around Kirdford has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Letting a property close to Billingshurst station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near The Parish Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What happens if it’s left?

It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Around Kirdford, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why book with us

  • An ARBOMaster approved applicator
  • A sealant colour to suit the surroundings
  • Colour agreed with you before we start
  • 20+ years of sealant experience

How the visit works

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. Somewhere like Kirdford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. The old mastic and anything lodged in the joint is removed.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Before we arrive

  • Mention any parking rules near the property
  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks

Advice

How to look after the new joints

Looking after new joints is easy:

  • Never let anyone fill a movement joint with mortar
  • Avoid pressure-washing directly into sealant joints
  • Show decorators and builders where the movement joints are
  • Do not let climbing plants root in the sealant

Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.

Different surfaces, different methods

Render joints

Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.

What affects the quote in Kirdford

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

  • The number and length of the joints
  • How many rooms, windows or areas are involved
  • The product the joint needs
  • Any working-time requirements on site

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Helping us quote

You do not need to know the technical terms. It helps if you can tell us:

  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs
  • Where the job is, and your postcode
  • A few photos by email, if you can

There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.
