Sand mastic for Ardington homes and businesses

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Ask a joiner to look at soft timber first
  • Ask us before painting near the mastic
  • Clear gutters so water doesn’t pour onto the windows
  • Find out about consent before window work on a listed home

Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.

Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

About our sand mastic in Ardington

Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on period & listed homes, brick reveals and stone surrounds, and the jobs we see most are tired mastic found when preparing windows for paint and failed mastic on an exposed elevation.

Around Ardington, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

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

Frames and glazing around Ardington

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Schools such as Wantage Primary Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

The process

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours per window, depending on the condition of the joints from start to finish. For a village or hamlet like Ardington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Move anything stored near the joints
  • Tell us about access, such as stairs, a lift or high-level joints

Advice

When it isn’t the sealant

We will always be straight with you, so here’s what new sealant won’t do:

  • Planning or listed building consent (your local planning authority decides)
  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Cracked or broken glass

If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

Surfaces we seal

  • Sash and case windows
  • Brick reveals
  • Period & listed homes
  • Tenement windows
  • Stone surrounds
  • Timber door frames

How we quote for sand mastic

We don’t publish a price list, because jobs vary so much. What we look at:

  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove
  • Whether there’s mould to deal with
  • Which sealant suits the joint

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Helping us quote

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

  • What’s wrong with the joints now
  • How many joints, rooms or windows are involved
  • Any previous sealing or DIY work
  • How we’d reach the joints

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

Different surfaces, different methods

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

Sash and case windows

Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.

Questions from Ardington

Is sand mastic in Ardington guaranteed?

All our work, in Ardington and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Do you cover Ardington for sand mastic?

Yes. We work across London and the South East, and Ardington is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.

What exactly is sand mastic?

It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Can I add another job to the visit?

Yes. Several rooms, windows or areas can go on one quote.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that normally means someone at home.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

Signs you need sand mastic in Ardington

Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.

If you can see any of these, it’s time to have the joints looked at:

  • Wind and rain getting in round a sash window
  • Window mastic to renew ahead of painting
  • Crumbling sand mastic round a window
  • Patchy fillers round a sash window

In the older streets around Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Choosing a sealant specialist

What happens if it’s left?

Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Ardington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
