Sand mastic for Ockley homes and businesses

What happens on the day

We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Ockley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic is not too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

Before we arrive

  • Keep children and pets away from the work area
  • Clear items away from the joints we’re working on
  • On commercial sites, let us know about site rules

Advice

How we handle sand mastic in Ockley

We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We work on stone surrounds, timber door frames and tenement windows, and the jobs we see most are wind and rain getting in round a sash window and mastic round period door frames that has failed.

Somewhere as small as Ockley, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

When to call us in Ockley

Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.

Look out for any of the following:

  • Mastic worn away on windows facing the weather
  • Modern sealant on a period surround
  • Open joints round the window box
  • Gaps round a timber door in stone or brick

For an older house near a landmark such as St John's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions to ask before you book

  • When the joint can take water or movement
  • Whether VAT is included
  • Whether all the old sealant comes out first
  • What product goes in the joint

Choosing a sealant specialist

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Keep modern sealant off the mastic
  • Avoid heavy scraping on the mastic joint
  • Get any rot dealt with first
  • Plan mastic work ahead of painting

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.

Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.

DIY sealant or a professional job?

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Quotes for sand mastic in Ockley

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

  • Any working-time requirements on site
  • Any mould that needs treating
  • The size of the job
  • Access and height

What it costs depends on how much there is to do, 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

There’s no need for technical detail. It helps if you can tell us:

  • Whether it’s a home or a business

  • What’s wrong with the joints now
  • The rough size of the job

How long does sand mastic take to go off?

When it is not the sealant

  • Broken panes
