Sand mastic near Bailey Green

Sand mastic in Bailey Green, done properly

Across Bailey Green, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on timber door frames, stone surrounds and brick reveals, and common reasons people get in touch are mastic dropping out of the joint and gaps round a timber door in stone or brick.

Homes in small places like Bailey Green 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.

Your job is guaranteed for a year, as with all our work.

Common problems we fix in Bailey Green

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

Most people get in touch when they notice one of these:

  • Gaps between timber frames and stone or brick
  • Old cement repairs round a window that have failed
  • Mastic round period door frames that has failed
  • Mastic that needs renewing before redecorating

Around Bailey Green, as everywhere, sand mastic is only as good as the preparation behind it.

Choosing a sealant specialist

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

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

Why it’s worth doing now in Bailey Green

Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Older cottages and farmhouses around Bailey Green can have timber 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, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Don’t run silicone over sand mastic
  • Ask the planning authority about consent for listed or conservation-area homes
  • Clear gutters so water doesn’t pour onto the windows
  • Check the mastic when you check the paintwork

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.

Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.

What happens on the day

We bring everything the job needs with us, so there’s nothing for you to buy. 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 like Bailey Green 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. 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.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any leaks or damp you’ve noticed

Windows and doors in Bailey Green

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. Historic houses like Hinton Ampner House (about 4.7 miles west) are a reminder that the area around Bailey Green 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 an older house near a landmark such as Holy Trinity Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
