External mastic in Weston

What sealant work can’t fix

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

  • Failed render or damaged cladding panels
  • Cracks in the bricks or render themselves, away from the joints
  • Rising or penetrating damp from elsewhere in the wall

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Joints and surfaces we work on

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

External mastic in Weston, done properly

Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have cracked joints where brick meets render or frames and old sealant gone brittle and cracked, we can put it right, whatever the surface.

Around Weston, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What happens if it’s left?

A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Weston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

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

How we quote for external mastic

We quote each job individually. These are the things that affect it:

  • Working hours on commercial sites
  • Whether there’s mould to deal with
  • How many rooms, windows or areas are involved
  • The number and length of the joints

The cost reflects the work involved, not guesswork. That is why we ask a few questions first.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

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

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or send us an email.

FAQs for Weston

Do you work for landlords with property near Petersfield station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Is Weston in your area for external mastic?

Yes, Weston is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Are you fully insured?

Yes. We’re fully insured, and we can confirm the details when we quote.

Can you reach joints on upper floors?

Each building is different. Send us pictures and a rough idea of the height.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.

Are you ARBOMaster approved?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

How long does the job take?

Most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll confirm how long when we quote.

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Tell anyone working on the walls about the movement joints
  • Leave the joints unpainted unless we’ve said otherwise
  • Make sure movement joints are not pointed over
  • Clear growth from the base of walls and joints

Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.

An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

What happens on the day

On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Weston, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at every joint and agree a colour to suit the wall.
  2. Failed sealant is removed back to clean, sound faces.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. We prime the faces where required.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Mention any parking rules near the property
  • Mention any tricky access

Walls and rooflines in Weston

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Uppark (about 4 miles south-east) are a reminder that the area around Weston 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.

Uppark, about 4 miles south-east, is one of the historic houses in the wider area around Weston, and older homes nearby need a sealant that suits their walls.

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

Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.
