Common questions in Whitewood

I let a flat near Godstone station. Can you help?

Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Do you cover smaller places like Whitewood?

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.

Where do you work from?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Are you an approved applicator?

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

Is it messy?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

How do I get a quote for external mastic in Whitewood?

We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Why do you put foam in the joint first?

The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.

External mastic in Whitewood, done properly

On houses, flats and commercial buildings across Whitewood, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Typical jobs include rigid filler in a joint that should flex and moss and dirt in joints with no sealant left, across render & cladding joints, concrete & block and copings & trims.

Somewhere as small as Whitewood, 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.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in Whitewood

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.

Any of these means the joints need attention:

  • Failed sealant between panels on a façade
  • Damp patches traced to an open external joint
  • Joints pointed up with cement by mistake
  • Gaps where render, brick and frames meet

For landlords with property near Godstone station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Before you book anyone

Quotes for external mastic in Whitewood

For a quick quote, just ask. What matters most is:

  • How many rooms, windows or areas are involved
  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out

Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What to tell us for a quote

When you contact us, it’s useful to know:

  • Where the property is
  • Photos by email, if that is easy
  • The type of property
  • What’s wrong with the joints now

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, ring 0345 464 0079 or email us.

Why it’s worth doing now in Whitewood

Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Whitewood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

How it works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere like Whitewood 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. We look at every joint and agree a colour to suit the wall.
  2. We take out the old sealant until the faces are sound.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

Getting ready for the visit

  • Move anything stored near the joints
  • Mention any parking rules near the property
  • Mention if the joints have been sealed before

How to look after the new joints

So the new joints stay in good condition:

  • Check external joints each spring
  • Make sure movement joints aren’t pointed over
  • Have failed joints looked at early
  • Point out the joints to other trades

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

Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

Surface by surface

Render joints

Water behind render can lead to blown patches. Resealing the joints early keeps water out.

Joints between dissimilar materials

Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.

What external mastic looks like in Whitewood

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.

Homes close to Church of St Mary the Virgin include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
