How the visit works

There is not much for you to do on the day. Point us to the joints and we will get on with it. 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 Hattingley, 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. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any parking rules near the property
  • On commercial sites, let us know about site rules

About our sand mastic in Hattingley

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with mastic that needs renewing before redecorating and crumbling sand mastic round a window, across brick reveals, period & listed homes and tenement windows.

Mastic can only go onto a dry, clean joint, so window work in Hattingley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Common problems we fix in Hattingley

Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.

It’s worth asking for a quote if you see:

  • Window mastic to renew ahead of painting
  • Mastic dropping out of the joint
  • Gaps round a timber door in stone or brick
  • Old cement repairs round a window that have failed

Schools such as Medstead Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What your quote should include

  • Who turns up on the day
  • How long the guarantee is
  • Which sealant they’ll use, and why
  • How hidden problems are handled

Choosing a sealant specialist

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Find out about consent before window work on a listed home
  • Make sure water runs off the sill
  • Look over the window mastic once a year
  • Ask a joiner to look at soft timber first

Look at the mastic when you look over the windows. Small cracks are easier to deal with early.

An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.

Hattingley homes and the weather

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. With historic houses such as Bentworth Hall (about 1.9 miles north-east) nearby, there’s older building stock in the area around Hattingley as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

For an older house near a landmark such as Church of St Andrew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Your questions about sand mastic in Hattingley

Do you cover Hattingley for sand mastic?

Yes. Our work covers London and the South East, and Hattingley is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.

Is sand mastic in Hattingley guaranteed?

All our work, in Hattingley and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.

Can old silicone round a sash window be swapped for sand mastic?

Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.

Do you do commercial work?

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

How do I get a quote for sand mastic in Hattingley?

It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

How long does sand mastic take?

That depends on how much there is to do, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We’ll give you a better idea when we quote.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
