Book sand mastic in Beckley Furnace

What we do, step by step

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Beckley Furnace, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

How to prepare

  • On commercial sites, let us know about site rules
  • Let us know about earlier repairs to the joints
  • Try not to wet indoor joints just before the visit

Sand mastic in Beckley Furnace, done properly

We work across Beckley Furnace renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on sash and case windows, tenement windows and brick reveals, and the jobs we see most are cement or filler used on old window joints that has cracked and old sand mastic that has cracked, crumbled or fallen out.

Somewhere as small as Beckley Furnace, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Each job carries a 12-month guarantee, whatever its size.

  • Cement or filler used on old window joints that has cracked
  • Mastic round period door frames that has failed
  • Silicone on a period window that looks wrong
  • Gaps between timber frames and stone or brick

What sand mastic looks like in Beckley Furnace

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Great Dixter (about 2.7 miles north) nearby, there’s older building stock in the area around Beckley Furnace as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

Leave it or put it right?

Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Beckley Furnace can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
