Your questions about external mastic in Padbury

Will you come out to Padbury?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is external mastic in Padbury guaranteed?

Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.

How do you reach high-level joints?

That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.

Why do you put foam in the joint first?

Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.

Is it OK to fill a movement joint with cement?

No. Cement or mortar cannot stretch. If it has already been filled, we can normally cut it out and reseal it.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can tenants book the work?

We can work for tenants, landlords or agents. Get your landlord’s agreement first.

How we handle external mastic in Padbury

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. Common call-outs are for sealant that has lost its bond to the brick or render and rigid filler in a joint that should flex, on render & cladding joints, joints between brick and frames and façade panels.

Outside joints can only be sealed when they’re dry, so work in Padbury is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Landlord and commercial work in Padbury

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Quotes for external mastic in Padbury

You’ll get a clear quote before any work starts. It takes into account:

  • When we can work, for business premises
  • Whether old sealant or filler has to be cut out
  • How many areas need sealing
  • Whether there’s mould to deal with

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • A few pictures by email, if you can
  • Whether it has been sealed before
  • Where the property is
  • The problem you’ve noticed

For external mastic in Padbury, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.

When it is not the sealant

Sealant is not the answer to every problem, and we will tell you before work begins. It won’t solve:

  • Structural movement, which needs a surveyor or engineer
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Cutting new joints into brickwork, which is building work rather than sealant work

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

Where we work in Padbury

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

Why act early in Padbury

It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. In a small place like Padbury, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Why us?

  • Approved under the ARBOMaster scheme
  • Fully insured
  • Colour agreed with you before work begins
  • More than 20 years in sealant work

Keeping the joints in good condition

So the new joints stay in good condition:

  • Deal with leaking gutters that soak the joints below
  • Keep soil, plants and ivy away from the joints
  • Show decorators and builders where the movement joints are
  • Wash walls gently around the sealant

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.

Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

Padbury buildings and the weather

Historic houses like Claydon House (about 3.3 miles south) are a reminder that the area around Padbury 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

In the older streets around Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Padbury Church of England School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What happens on the day

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. Somewhere like Padbury 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. First, the joints are inspected and the access agreed.
  2. We cut out the old mastic and rake out anything in the joint.
  3. The faces are brushed clean and primed where the product requires it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. We apply the sealant, tool it and check the whole run.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before
  • Keep pets and children clear of the area while we work
