Need external mastic in Woodnesborough?

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Show decorators and builders where the movement joints are
  • Never let anyone fill a movement joint with mortar
  • Act on the first splits you see
  • Avoid pressure-washing directly into sealant joints

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

Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

External mastic for homes and businesses in Woodnesborough

Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on joints between brick and frames, render & cladding joints and brickwork movement joints, and people most often call us about rain getting behind render or cladding at a joint and joints with sealant missing in places.

In a village or hamlet like Woodnesborough, 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.

All our work comes with our 12-month guarantee, wherever you are in Kent.

Signs you need external mastic in Woodnesborough

Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.

The most common problems we see are:

  • Water getting into walls through failed joints
  • Plants rooting in failed movement joints
  • Old sealant gone brittle and cracked
  • Rigid filler in a joint that should flex

Rented homes near Sandwich station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Questions to ask before you book

  • Whether they seal over old material or remove it
  • The length of the guarantee
  • Who does the work, and how experienced they are
  • Which sealant they’ll use, and why

Choosing a sealant specialist

What affects the quote in Woodnesborough

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • Which sealant suits the joint
  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • How easy the joints are to reach

Doing several joints on one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.

What we need to know

Photos by email are helpful but not essential. Please mention:

  • What’s wrong with the joints now
  • Pictures of the joints, sent by email
  • Where the job is, and your postcode
  • Roughly how big the job is

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or send us an email.

What happens on the day

We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. For a village or hamlet like Woodnesborough, the journey is planned in advance: 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 we look over the joints with you, agree which to renew and talk through access.
  2. Old sealant and any debris are cut and raked out.
  3. Both sides are cleaned back to sound material and primed if needed.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Mention any leaks or damp you’ve noticed
  • Clear items away from the joints we are working on

Advice

Woodnesborough questions

Will you come out to Woodnesborough?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you help a landlord with a rental near Sandwich station?

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

What is a movement joint?

Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

What do you need from me for a quote?

Let us know what needs doing and where, with photos by email if possible. If we need more, we’ll ask.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Woodnesborough buildings and the weather

Historic houses like Goodnestone Park (about 3.8 miles west) are a reminder that the area around Woodnesborough has older buildings as well as new. Where a home is older, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For an older house near a landmark such as Church of St Mary the Virgin, 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 Sandwich Technology School, its movement joints, gutters and trims need looking after like any other building’s.

Surface by surface

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.

Cladding and façade panels

If the façade has a specified sealant, that’s what we use. Tell us what the building has when you get in touch.

Why act early in Woodnesborough

The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In a small place like Woodnesborough, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
