How we handle external mastic in Sutton Scotney

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 line blends in. If you have rigid filler in a joint that should flex and panel joints letting water in, we can put it right, whatever the surface.

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

There’s a 12-month guarantee on every job, large or small.

What sealant work cannot fix

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Loose or hollow render, which needs re-rendering

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

What we seal

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

What affects the cost of external mastic

We quote each job individually. This is what makes a difference:

  • The product the joint needs
  • The size of the job
  • Whether the work is at height
  • Any mould that needs treating

What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.

Helping us quote

Photos by email are helpful but not essential. Please mention:

  • A few photos by email, if you can
  • If someone has resealed it before
  • How we’d reach the joints
  • Roughly how big the job is

If you’re in Sutton Scotney and need external mastic, call 0345 464 0079 or drop us an email. Tell us what the problem is and where, and you’ll get a clear quote before work begins.

Why act early in Sutton Scotney

A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Around Sutton Scotney, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Different surfaces, different methods

Joints between dissimilar materials

Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so the movement is taken up.

Render joints

Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.

Can I do it myself?

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 fails, we can still redo it.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What we do, step by step

At the end, we look at the finished work together. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. Somewhere like Sutton Scotney 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. 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. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
