About our sand mastic in East Horndon

If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Typical jobs include crumbling sand mastic round a window and gaps round a timber door in stone or brick, on brick reveals, timber door frames and tenement windows.

Somewhere as small as East Horndon, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

All our work is covered by our one-year guarantee.

What sand mastic looks like in East Horndon

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Letting a property close to West Horndon station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as West Horndon Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around All Saints Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

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.

What affects the quote in East Horndon

Jobs vary more than people expect. The main factors:

  • How many areas need sealing
  • The old material and how stubborn it is
  • Whether there’s mould to deal with
  • Which sealant suits the joint

What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What we need to know

Before you ask for a quote, have a think about:

  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved
  • Where the property is
  • If it’s domestic, commercial or a hotel

To get a quote, phone 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before we start.

Why act early in East Horndon

Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Older cottages and farmhouses around East Horndon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

How it works

We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours per window, depending on the condition of the joints. For a village or hamlet like East Horndon, the journey is planned in advance: 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 check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Keep children and pets away from the work area
  • Mention any tricky access
