Sand mastic for Great Bardfield homes and businesses

Sand mastic for homes and businesses in Great Bardfield

Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We are often asked to deal with tired mastic found when preparing windows for paint and wind and rain getting in round a sash window, on stone surrounds, sash and case windows and period & listed homes.

In a village or hamlet like Great Bardfield, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition

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

  • Sort the mastic before the decorators arrive
  • Find out about consent before window work on a listed home
  • Inspect the joints round the windows every year or so
  • Avoid heavy scraping on the mastic joint

Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.

Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

How the visit works

At the end, we look at the finished work together. The work normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. Somewhere as small as Great Bardfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area
  • Tell us if parking is tricky

Surface by surface

Brick reveals

An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

Period and listed homes

Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.

What we’re called out for in Great Bardfield

Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they usually need raking out.

People usually contact us after spotting something like this:

  • Wind and rain getting in round a sash window
  • Modern sealant on a period surround
  • Gaps between timber frames and stone or brick
  • Failed mastic on an exposed elevation

For site and facilities teams at buildings such as Great Bardfield Primary School, the mastic around its windows and doors needs looking after like any other building’s.

  • Whether the sealant suits the joint
  • Whether they seal over old material or remove it

Our hiring checklist

Great Bardfield homes and the weather

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.

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

Common questions in Great Bardfield

Is Great Bardfield within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is there a guarantee on sand mastic in Great Bardfield?

Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.

Can you seal over the old sealant?

No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.

Is it possible to paint over sand mastic?

Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

Can you replace silicone on a period window with sand mastic?

Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before resealing.

How do I get a quote for sand mastic in Great Bardfield?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
