Trusted sand mastic in Sible Hedingham

When to call us in Sible Hedingham

Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they generally need raking out.

The most common problems we see are:

  • Mastic worn away on windows facing the weather
  • Silicone on a period window that looks wrong
  • Gaps between timber frames and stone or brick
  • Old sand mastic that has cracked, crumbled or fallen out

If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

  • Who turns up on the day

Our hiring checklist

Sand mastic in Sible Hedingham

For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on stone surrounds, tenement windows and sash and case windows, and common reasons people get in touch are gaps where the frame meets the masonry and cement or filler used on old window joints that has cracked.

Around Sible Hedingham, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

How the visit works

The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job normally takes a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. For a job in Sible Hedingham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Getting ready for the visit

  • Mention any tricky access
  • Clear the area around the work

Leave it or put it right?

If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Around Sible Hedingham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How the job changes by surface

Timber door frames

Sand mastic is used round timber door frames too. We renew it the same way as on windows.

Stone surrounds

We take care not to mark the stone when the old mastic comes out.

Honest limits

We won’t take on work that will not last, so these are the limits:

  • Damaged stone surrounds
  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Whether work needs listed building consent

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

Where we work in Sible Hedingham

  • Sash and case windows
  • Stone surrounds
  • Period & listed homes

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Windows and doors in Sible Hedingham

London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Hedingham Castle (about 1.1 miles north-east) nearby, there’s older building stock in the area around Sible Hedingham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Schools such as Hedingham School and Sixth Form are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Avoid heavy scraping on the mastic joint
  • Check with your local planning authority if your home is listed
  • Leave the new mastic unpainted
  • Have rotten timber repaired before new mastic goes in

Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
