How we handle external mastic in Ickleford

Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. We work on joints between brick and frames, façade panels and brickwork movement joints, and common reasons people get in touch are rigid filler in a joint that should flex and gaps where render, brick and frames meet.

Outside joints can only be sealed when they’re dry, so work in Ickleford 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, whatever its size.

Ickleford buildings and the weather

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

In the older streets around Church of St Katharine, the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Hitchin station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Why it’s worth doing now in Ickleford

The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render, so the damage spreads beyond the joint. Older cottages and farmhouses around Ickleford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Can I do it myself?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Landlord and commercial work in Ickleford

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Ickleford questions

Is Ickleford within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is Ickleford in your area for external mastic?

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

What do you need from me for a quote?

Let us know what needs doing and where. If we need more, we will ask.

When is the sealant fully cured?

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

When will the joints need doing again?

There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.

How do you reach high-level joints?

It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.

I rent my home. Can I book you?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

Are you fully insured?

Yes. We are fully insured.

Common problems we fix in Ickleford

Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.

Keep an eye out for any of the following:

  • Water getting into walls through failed joints
  • Plants rooting in failed movement joints
  • Old sealant gone brittle and cracked
  • Joints pointed up with cement by mistake

For site and facilities teams at buildings such as Ickleford Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Our hiring checklist

How the visit works

When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work generally takes anything from a few hours to several days, depending on the building. Somewhere as small as Ickleford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules

What we cannot put right

Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Failed render or damaged cladding panels
  • Structural movement, which needs a surveyor or engineer

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

What we seal

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

How we quote for external mastic

There’s no set price list, because no two jobs are the same. What we look at:

  • The product the joint needs
  • How easy the joints are to reach
  • Whether there’s mould to deal with
  • The old material and how stubborn it is

Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

What we need to know

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Any previous sealing or DIY work
  • Any access issues, like height or stairs
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel
