External mastic in Burnt Heath, done properly

Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. We’re often asked to deal with sealant that has lost its bond to the brick or render and movement joints filled with mortar instead of sealant, across brickwork movement joints, joints between brick and frames and façade panels.

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

You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

What the job involves on each surface

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.

Copings and trims

Metal and stone copings both move with temperature, so a flexible sealant suits them best year round.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Point out the joints to other trades
  • Leave the joints unpainted unless we’ve said otherwise
  • Don’t let climbing plants root in the sealant
  • Deal with leaking gutters that soak the joints below

Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.

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

Do you need external mastic in Burnt Heath?

Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.

If you can see any of these, it’s time to have the joints looked at:

  • Joints with sealant missing in places
  • Gaps where render, brick and frames meet
  • Rain getting behind render or cladding at a joint
  • Old sealant gone brittle and cracked

If you let a flat or house near Manningtree station, split movement joints are easy to miss on a rental until damp shows inside.

Questions from Burnt Heath

Can you do external mastic in Burnt Heath?

Yes. We work across London and the South East, and Burnt Heath is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Do you cover smaller places like Burnt Heath?

Yes, Burnt Heath is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Will you leave a mess?

Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

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.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

When is the sealant fully cured?

That depends on the sealant used, so follow the cure time we give you when we finish.

When will the joints need doing again?

It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges.

Outside joints around Burnt Heath

Historic houses like Castle House (about 2.6 miles north) are a reminder that the area around Burnt Heath 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. 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.

Homes close to Church of St Mary include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Why act early in Burnt Heath

Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. Older cottages and farmhouses around Burnt Heath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How the visit works

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. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Burnt Heath, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about earlier repairs to the joints

How we quote for external mastic

For a quick quote, just ask. The main things that affect it are:

  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • Any working-time requirements on site
  • The size of the job

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Asking for a quote

Before you ask for a quote, have a think about:

  • Photos by email, if that’s easy
  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved
  • What the problem is, such as mould, gaps, leaks or cracking

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or email us.

DIY sealant or a professional job?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

If you are set on DIY, put the effort into 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.
