What we cannot put right

Before booking, it’s worth knowing the limits:

  • Adding movement joints to masonry that has none
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.

Surfaces we seal

  • Render & cladding joints
  • Brickwork movement joints
  • Concrete & block
  • Façade panels

  • Joints between brick and frames

External mastic in Chambers' Green, done properly

We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. If you are dealing with joints pointed up with cement by mistake and hard, crazed mastic that has stopped moving, we can help, whatever the surface.

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

A one-year guarantee comes as standard, so you are not left on your own once the job is done.

FAQs for Chambers' Green

Do you cover smaller places like Chambers' Green?

Yes, we do. We work across 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 Pluckley station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

How long does external mastic take?

A typical job takes anything from a few hours to several days, depending on the building, including preparation and clearing up. We will confirm how long when we quote.

When is the sealant fully cured?

Different products cure at different speeds, so please follow the time we give you.

Can you seal joints between two different materials?

Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

What does external mastic cost?

Size, access and the old material all affect the cost. Ask us for a quote.

What affects the quote in Chambers' Green

You will get a clear quote before any work starts. It’s based on:

  • The number of rooms or windows
  • The size of the job
  • Whether the work is at height
  • The old material and how stubborn it is

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • Where the property is
  • Photos by email, if that’s easy
  • Whether it’s a home or a business
  • The problem you’ve noticed

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What happens on the day

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Chambers' Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. We take out the old sealant until the faces are sound.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work

Advice

Looking after it afterwards

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Check the sealant is paintable before painting near it
  • Keep high-pressure jets off the joints
  • Show decorators and builders where the movement joints are
  • Keep movement joints as flexible joints, not mortar

Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.

Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.

What happens if it’s left?

A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In a small place like Chambers' Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Why us?

  • More than 20 years in sealant work
  • ARBOMaster approved applicator

What external mastic looks like in Chambers' Green

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. With historic houses such as Godinton House (about 3.7 miles east) nearby, there’s older building stock in the area around Chambers' Green as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

If you let a flat or house near Pluckley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Pluckley Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Nicholas include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
