External mastic for Beenham Stocks homes and businesses

External mastic in Beenham Stocks, done properly

Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We are often asked to deal with rigid filler in a joint that should flex and sealant pulling away from one side of the joint, across render & cladding joints, façade panels and concrete & block.

Around Beenham Stocks, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

The process

Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Beenham Stocks, the journey is planned in advance: 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. 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. The joint faces are cleaned and primed where the sealant needs it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

How to prepare

  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any water getting in

Landlord and commercial work in Beenham Stocks

Letting agents and landlords in Beenham Stocks can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Check external joints each spring
  • Keep movement joints as flexible joints, not mortar
  • Keep soil, plants and ivy away from the joints
  • Tell anyone working on the walls about the movement joints

Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.

Small splits are the time to act. At that stage it’s a simple cut out and reseal.

When it isn’t the sealant

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Structural movement, which needs a surveyor or engineer
  • Loose or hollow render, which needs re-rendering
  • Cutting new joints into brickwork, which is building work rather than sealant work

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

Where we work in Beenham Stocks

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

What happens if it’s left?

Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Older cottages and farmhouses around Beenham Stocks can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

  • ARBOMaster approved applicator
  • Trusted Arbo and Everbuild sealants

Beenham Stocks questions

Do you work for landlords with property near Aldermaston station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you cover smaller places like Beenham Stocks?

Yes. Beenham Stocks is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can you seal over the old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Do you guarantee your work?

Yes. All our work carries a 12-month guarantee.

Do you take out the old sealant first?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.

How long does the job take?

It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We will give you a better idea when we quote.

Signs you need external mastic in Beenham Stocks

Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.

Common reasons people contact us include:

  • Panel joints letting water in
  • Plants rooting in failed movement joints
  • Weathered mastic that no longer stretches
  • Brick movement joints where the sealant has split

If you let a flat or house near Aldermaston station, outside joints that have cracked can let damp into a rental, so check them between lets.

Questions to ask before booking

  • How the surfaces are prepared before sealing
  • Whether they seal over old material or remove it
  • Whether they’re fully insured
  • When the joint can take water or movement

Choosing a sealant specialist

Outside joints around Beenham Stocks

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.

For site and facilities teams at buildings such as Beenham Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Different surfaces, different methods

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it so the sealant is not too deep.

Joints between dissimilar materials

Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so the movement is taken up.
