External mastic for Farleigh Green homes and businesses

DIY sealant or a professional job?

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.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

How we handle external mastic in Farleigh Green

As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. If you have plants rooting in failed movement joints and panel joints letting water in, we can put it right, on concrete & block, façade panels and render & cladding joints alike.

Older homes in small places like Farleigh Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

Every job comes with a 12-month guarantee.

Farleigh Green questions

Is Farleigh Green within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you help a landlord with a rental near East Farleigh station?

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

Are you fully insured?

Yes, we’re fully insured.

What is backing rod for?

That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.

Do you work for hotels and businesses?

Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.

Why is there a gap in my brick wall?

A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.

Can you seal joints between render and window frames?

Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.

When is the sealant fully cured?

Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.

How it works

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. Somewhere like Farleigh Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. Old sealant and any debris are cut and raked out.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Before we arrive

  • On commercial sites, let us know about site rules
  • Let us know if you’ve seen damp or leaks
  • Keep pets and children clear of the area while we work

What affects the quote in Farleigh Green

Jobs vary more than people expect. The main factors:

  • How much old sealant there is and how hard it is to remove
  • The type of sealant required
  • The number and length of the joints
  • How many rooms, windows or areas are involved

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What to tell us for a quote

When you call or email, it’s useful to know:

  • A few photos by email, if you can
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Leave the joints unpainted unless we have said otherwise
  • Fix overflowing gutters above sealed joints
  • Walk round the building once a year and look at the joints
  • Keep movement joints as flexible joints, not mortar

Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.

Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.

Honest limits

To be straight with you, there are a few things sealant won’t fix:

  • Failed render or damaged cladding panels
  • Movement that is more than a sealant joint can take
  • Walls that need new movement joints cut into them

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

What we seal

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

What happens if it’s left?

It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way. In a small place like Farleigh Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

Walls and rooflines in Farleigh Green

With historic houses such as Stoneacre (about 4.9 miles east) nearby, there’s older building stock in the area around Farleigh Green as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.

If you look after a building such as East Farleigh Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around All Saints Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near East Farleigh station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
