  • Putty and glazing repairs
  • Crumbling stone or brickwork round the window
  • Decayed frames that need repair

How we handle sand mastic in Brandfold

Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We work on period & listed homes, tenement windows and sash and case windows, and the jobs we see most are mastic round period door frames that has failed and draughty sash windows at the surround.

Homes in small places like Brandfold 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.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What sand mastic looks like in Brandfold

With historic houses such as Scotney Castle (about 3.5 miles south-west) nearby, there’s older building stock in the area around Brandfold as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

For site and facilities teams at buildings such as Goudhurst and Kilndown Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to St Mary's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens on the day

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere like Brandfold needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. Deep voids are packed so the mastic is the right thickness.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. The mastic is finished to sit tidily against the stone or brick.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Try not to wet indoor joints just before the visit
  • Mention any parking rules near the property

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

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. In a small place like Brandfold, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.
