External mastic in Chafford Hundred

External mastic for homes and businesses in Chafford Hundred

External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on façade panels, joints between brick and frames and render & cladding joints, and people most often call us about gaps where render, brick and frames meet and rain getting behind render or cladding at a joint.

Around Chafford Hundred, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Quotes for external mastic in Chafford Hundred

We do not publish a price list, because no two jobs are the same.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

  • When we can work, for business premises
  • How much there is to do
  • How many areas need sealing
  • Whether the work is at height

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

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • Whether it has been sealed before
  • The address or postcode of the job
  • If it’s domestic, commercial or a hotel
  • A few pictures by email, if you can

There’s no standard price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.

Signs you need external mastic in Chafford Hundred

Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.

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

  • Failed seals between different materials
  • Movement joints filled with mortar instead of sealant
  • Moss and dirt in joints with no sealant left
  • Damp patches traced to an open external joint

For landlords with property near Grays station, outside joints that have cracked can let damp into a rental, so check them between lets.

Before you book anyone

  • What happens if they find a problem under the old sealant
  • Whether VAT is included
  • What the cure time is

Our hiring checklist

What we cannot put right

A few problems are outside what sealant work can do:

  • Subsidence or other structural problems
  • Render that’s blown, hollow or coming away
  • Cracks in the bricks or render themselves, away from the joints

If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Chafford Hundred buildings and the weather

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For an older house near a landmark such as All Saints' Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Tudor Court Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Why deal with it now?

Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Homes in smaller places like Chafford Hundred can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Questions from Chafford Hundred

Will you come out to Chafford Hundred?

Yes, Chafford Hundred is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you work for landlords with property near Grays station?

Yes, landlords and agents are among the people we work for, 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 remove the old sealant?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.

Is the work guaranteed?

Yes. All our work carries a 12-month guarantee.

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. If it doesn’t work out, we can redo it.

How often do external joints need resealing?

There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.

Do you do commercial work?

Yes, regularly. Larger jobs can be planned room by room or area by area.

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the building. Parking around Chafford Hundred is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  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. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Move anything stored near the joints
  • On commercial sites, let us know about site rules

Landlord and commercial work in Chafford Hundred

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Landlords and letting agents in Chafford Hundred can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Have failed joints looked at early
  • Point out the joints to other trades
  • Never let anyone fill a movement joint with mortar
  • Keep high-pressure jets off the joints

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.

Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
