Maple End buildings and the weather

Historic houses like Audley End House (about 4.5 miles west) are a reminder that the area around Maple End 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Schools such as Radwinter Church of England Voluntary Aided Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

External mastic for homes and businesses in Maple End

On houses, flats and commercial buildings across Maple End, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We are often asked to deal with joints where the bead has come unstuck and joints with sealant missing in places, on façade panels, copings & trims and render & cladding joints.

Somewhere as small as Maple End, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

When it isn’t the sealant

We won’t take on work that won’t last, so these are the limits:

  • 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
  • Cracked brickwork or render that needs a builder or plasterer

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

Surfaces we seal

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

Maple End questions

Is Maple End within the area you cover?

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

Is Maple End in your area for external mastic?

Yes. We work across London and the South East, and Maple End is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.

Can a movement joint be filled with mortar?

No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.

Will the new joint stand out?

There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.

How long does external mastic take?

As a guide, most jobs take anything from a few hours to several days, depending on the building. Bigger jobs take longer, and we’ll say how long yours will take.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Can new sealant go over the old?

No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Why is there a gap in my brick wall?

It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Keep high-pressure jets off the joints
  • Get split or bare joints resealed while the damage is small
  • Keep movement joints as flexible joints, not mortar
  • Show decorators and builders where the movement joints are

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

Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

What we’re called out for in Maple End

The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.

Look out for these signs:

  • Rain getting behind render or cladding at a joint
  • Failed sealant between panels on a façade
  • Rigid filler in a joint that should flex
  • Plants rooting in failed movement joints

Homes close to Church of All Saints include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How to choose a mastic man

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation, and the area is left clean. Somewhere as small as Maple End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, the joints are inspected and the access agreed.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. We fit closed-cell backing rod to control the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Before we arrive

  • Clear items away from the joints we are working on
  • Keep pets and children clear of the area while we work
  • Mention any parking rules near the property

Surface by surface

Brickwork movement joints

Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.

Render joints

Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.

Work for landlords, hotels and businesses

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.

We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
