Trusted sand mastic in Workhouse Hill

Sand mastic in Workhouse Hill, done properly

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 work on stone surrounds, timber door frames and tenement windows, and people most often call us about old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes.

Mastic can only go onto a dry, clean joint, so window work in Workhouse Hill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

Every job is covered by a one-year guarantee.

Sand mastic in Workhouse Hill: local notes

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Castle House (about 4 miles east) are a reminder that the area around Workhouse Hill 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.

If you look after a building such as Boxted St Peter's Church of England School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Workhouse Hill questions

Is Workhouse Hill in your area for sand mastic?

Where is Mr Mastic based?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.

Is sand mastic better than silicone for my windows?

For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.

Should I check with the council before work on a listed or conservation-area home?

Check with your local planning authority. They decide whether consent is needed.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Can I paint the new mastic?

It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Looking after it afterwards

Aftercare is simple:

  • Sort the mastic before the decorators arrive
  • Don’t run silicone over sand mastic
  • Find out about consent before window work on a listed home
  • Check the mastic when you check the paintwork

Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.

It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

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

The process

We bring everything the job needs with us, so you don’t need to buy or prepare anything. 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. Somewhere as small as Workhouse Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check the window surrounds and agree which joints need renewing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The finish is dressed so it sits neatly against the stone or brick.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work
  • Mention any leaks or damp you’ve noticed
