Sand mastic for homes and businesses in Anvil Green

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on timber door frames, tenement windows and brick reveals, and the jobs we see most are old cement repairs round a window that have failed and mastic round period door frames that has failed.

Homes in small places like Anvil Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

We stand behind the work with a 12-month guarantee.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

When it is not the sealant

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Cracked or broken glass
  • Damaged stone surrounds
  • Timber that has rotted

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Surfaces we seal

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

What we do, step by step

You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a single window, longer for several for a typical job. Somewhere like Anvil Green needs a little journey planning: 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. Old, loose mastic is raked out and the joint cleaned.
  3. Deep voids are packed so the mastic is the right thickness.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Mention any tricky access
  • Let us know about parking restrictions

Anvil Green questions

Can you help a landlord with a rental near Chilham station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Can you do sand mastic in Anvil Green?

Yes, Anvil Green is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Do you do commercial work?

Yes. Larger jobs can be planned room by room or area by area to suit the site.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Do you take out the old sealant first?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Do you guarantee sand mastic work?

Every job comes with our one-year guarantee.

What does sand mastic cost?

Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us with a short description of the job.

Is it possible to take out silicone and use sand mastic instead?

In most cases. We remove the silicone and clean the joint before the sand mastic goes in.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Keep modern sealant off the mastic
  • Do not paint over the new mastic
  • Renew mastic before redecorating the windows
  • Look over the window mastic once a year

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.

Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

What sand mastic looks like in Anvil Green

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.

If you let a flat or house near Chilham station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Bartholomew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why deal with it now?

Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Anvil Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.
