External mastic near Staplecross

External mastic for homes and businesses in Staplecross

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint does not stand out. If you are dealing with gaps where render, brick and frames meet and sealant pulling away from one side of the joint, we can put it right, on copings & trims, render & cladding joints and concrete & block alike.

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

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

Different surfaces, different methods

Render joints

Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

What external mastic looks like in Staplecross

London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Durhamford Manor (about 2.4 miles south) are a reminder that the area around Staplecross has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

If you let a flat or house near Robertsbridge station, outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near St Marks Staplecross, an extension built onto an older house moves differently, and the joint between them takes the strain.

When to call us in Staplecross

If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.

Most people get in touch when they notice something like this:

  • Moss and dirt in joints with no sealant left
  • Gaps where render, brick and frames meet
  • Movement joints filled with mortar instead of sealant
  • Rain getting behind render or cladding at a joint

If you look after a building such as Staplecross Methodist Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How to choose a mastic man

Why it’s worth doing now in Staplecross

Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Staplecross, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

How to look after the new joints

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

  • Check the sealant is paintable before painting near it
  • Keep movement joints as flexible joints, not mortar
  • Fix overflowing gutters above sealed joints
  • Wash walls gently around the sealant

Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.

A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. Somewhere like Staplecross needs a little journey planning: let us know about lanes, gates and parking. 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. 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.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height

Related advice

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

If you’re 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.

Questions from Staplecross

Can you do external mastic in Staplecross?

Yes. We work across London and the South East, and Staplecross is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

Can you help a landlord with a rental near Robertsbridge station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Can you work on commercial sites?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

What information do you need?

A short description and the location. If we need more, we will ask.

Are you fully insured?

Yes. We’re fully insured.

Can I do it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Can you seal over the old sealant?

No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
