About our sand mastic in Chillerton

We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, tenement windows and period & listed homes, and common reasons people get in touch are gaps where the frame meets the masonry and mastic that needs renewing before redecorating.

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

All our work is covered by a one-year guarantee, wherever you are in the Isle of Wight.

Quotes for sand mastic in Chillerton

Jobs vary more than people expect. What affects the quote:

  • Whether there’s mould to deal with
  • When we can work, for business premises
  • The product the joint needs
  • How much old sealant there is and how hard it is to remove

Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Signs you need sand mastic in Chillerton

Timber frames move with the seasons. The movement cracks the mastic over time.

People normally contact us when they notice one of these:

  • Gaps where the frame meets the masonry
  • Wind and rain getting in round a sash window
  • Cracked mastic round a front door frame
  • Mastic dropping out of the joint

Managing a site like Chillerton and Rookley Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Chillerton

Is there a guarantee on sand mastic in Chillerton?

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

Do you cover smaller places like Chillerton?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do several jobs on one visit?

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

What should I tell you?

Tell us what needs doing and where. We will ask anything else we need to know.

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

Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.

Will there be a smell?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

Where do you work from?

We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

What exactly is sand mastic?

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

How to look after the new joints

After the cure time, these simple habits help:

  • Plan mastic work ahead of painting
  • Make sure water runs off the sill
  • Inspect the joints round the windows every year or so
  • Leave the new mastic unpainted

Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.

Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.

Frames and glazing around Chillerton

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Sheat Manor (about 0.6 miles north-east) are a reminder that the area around Chillerton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

For an older house near a landmark such as St. Olave's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

How the visit works

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours per window, depending on the condition of the joints. In a small place like Chillerton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Getting ready for the visit

  • Tell us about any water getting in
  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints
