Why act early in Surrey Quays

Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Surrey Quays.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.

External mastic for homes and businesses in Surrey Quays

On houses, flats and commercial buildings across Surrey Quays, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you’re dealing with sealant pulling away from one side of the joint and movement joints filled with mortar instead of sealant, we can help, whatever the surface.

London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Surrey Quays, check the lease for who looks after the outside.

You get a one-year guarantee, the same in Surrey Quays as everywhere else we work.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Outside joints around Surrey Quays

London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you live in an older home near St Katharine with St Bartholomew, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Rotherhithe Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

When something else is needed

It helps to know what we cannot do too:

  • Movement that is more than a sealant joint can take
  • Damp that is not coming from the joint
  • Cracking across the wall rather than at a joint

If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

What we seal

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

How to look after the new joints

After the cure time, these simple habits help:

  • Act on the first splits you see
  • Walk round the building once a year and look at the joints
  • Show decorators and builders where the movement joints are
  • Keep water from gutters off the wall

Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.

If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

Questions from Surrey Quays

Can you do external mastic in Surrey Quays?

Yes. Our work covers London and the South East, and Surrey Quays is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Can parking be tricky for a visit in Surrey Quays?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

How long does external mastic last?

It varies from wall to wall: 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.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.

Will the new joint stand out?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it does not stand out.

Is there a guarantee?

Yes. Every job comes with our one-year guarantee.

How do you reach high-level joints?

That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

When to call us in Surrey Quays

Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.

These are the problems we are asked about most:

  • Movement joints with cracked, split or missing sealant
  • Water getting into walls through failed joints
  • Plants rooting in failed movement joints
  • Gaps where render, brick and frames meet

As a London address, Surrey Quays can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Our hiring checklist

How the visit works

On the day, we start by going over the job with you. Surfaces next to the work are protected before work begins. The work normally takes anything from a few hours to several days, depending on the building. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Surrey Quays. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  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

  • Keep pets and children clear of the area while we work
  • Tell us about any water getting in
  • Move anything stored near the joints
