Sand mastic in Kirby-le-Soken

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 and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on timber door frames, tenement windows and stone surrounds, and common reasons people get in touch are patchy fillers round a sash window and gaps round a timber door in stone or brick.

In a village or hamlet like Kirby-le-Soken, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Big or small, you get the same one-year guarantee.

Common problems we fix in Kirby-le-Soken

Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.

These are the problems we’re asked about most:

  • A silicone bead on a sash window that spoils the look
  • Tired mastic found when preparing windows for paint
  • Crumbling sand mastic round a window
  • Cement or filler used on old window joints that has cracked

If you look after a building such as Kirby Primary Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Choosing a sealant specialist

Windows and doors in Kirby-le-Soken

Kirby-le-Soken is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Thorpe Hall (about 2.4 miles west) are a reminder that the area around Kirby-le-Soken has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

For landlords with property near Kirby Cross station, any sash windows need sound mastic to keep draughts and rain out. Homes close to Church of St Michael include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

What happens if it’s left?

If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Around Kirby-le-Soken, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

What the job involves on each surface

Timber door frames

Round a period front door, sand mastic gives the right look.

Brick reveals

Loose mastic comes out and deep gaps are packed before the new mastic goes in.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Kirby-le-Soken: your questions answered

Will you come out to Kirby-le-Soken?

Yes, Kirby-le-Soken is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Does living near the coast affect sand mastic in Kirby-le-Soken?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.

What is sand mastic?

A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.

Is it possible to paint over sand mastic?

The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we’ll talk you through it.

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

Do you work for hotels and businesses?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

Which is right for my windows, sand mastic or modern sealant?

That depends on your windows. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.

What we do, step by step

Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Somewhere like Kirby-le-Soken needs a little journey planning: 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. 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.

Preparing for the visit

  • Clear the area around the work
  • Plan for the work area to be out of bounds to pets and children
  • For indoor joints, keep the area dry beforehand if you can
