External mastic near Horsebridge

About our external mastic in Horsebridge

We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. We work on joints between brick and frames, render & cladding joints and copings & trims, and the jobs we see most are panel joints letting water in and damp patches traced to an open external joint.

In a village or hamlet like Horsebridge, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

Whatever the size of the job, it’s backed by our 12-month guarantee.

What external mastic looks like in Horsebridge

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Mottisfont Abbey (about 2.5 miles south-west) are a reminder that the area around Horsebridge 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.

If you live in an older home near Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as King's Somborne Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Horsebridge: your questions answered

I let a flat near Mottisfont & Dunbridge station. Can you help?

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

Do you cover Horsebridge for external mastic?

Yes. Our work covers London and the South East, and Horsebridge is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.

Can you seal joints between two different materials?

Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.

What information do you need?

A short description and the location. If we need more, we will ask.

Can you reach joints on upper floors?

It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.

Can I do it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Do I need to be at home?

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.

Will it make a mess?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Failed render or damaged cladding panels
  • Structural movement, which needs a surveyor or engineer
  • Cracked brickwork or render that needs a builder or plasterer

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

What we seal

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

What we do, step by step

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Horsebridge, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Both sides are cleaned back to sound material and primed if needed.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

How to prepare

  • Keep children and pets away from the work area
  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive

Advice

Signs you need external mastic in Horsebridge

Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.

The most common problems we see are:

  • Movement joints with cracked, split or missing sealant
  • Gaps where render, brick and frames meet
  • Water getting into walls through failed joints
  • Hard, crazed mastic that has stopped moving

Letting a property close to Mottisfont & Dunbridge station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Before you book anyone

  • Whether the sealant suits the joint
  • What happens if the job turns out different
  • The length of the guarantee
  • Who does the work, and how experienced they are

Choosing a sealant specialist

What happens if it’s left?

Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. In a small place like Horsebridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

Can I do it myself?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Work for landlords, hotels and businesses

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Tell anyone working on the walls about the movement joints
  • Get split or bare joints resealed while the damage is small
  • Make sure movement joints are not pointed over
  • Clear growth from the base of walls and joints

Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.

Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
