Sand mastic for homes and businesses in Burghclere Common

Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. We are often asked to deal with mastic round period door frames that has failed and crumbling sand mastic round a window, across brick reveals, stone surrounds and sash and case windows.

Homes in small places like Burghclere Common 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.

Every job comes with our 12-month guarantee.

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Different surfaces, different methods

Stone surrounds

Sand mastic sits naturally against stone. The finish blends with the masonry.

Period and listed homes

A traditional finish suits a period property, and sand mastic is one of them.

Sand mastic in Burghclere Common: local notes

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Highclere Castle (about 2.7 miles south-west) nearby, there’s older building stock in the area around Burghclere Common 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.

Letting a property close to Newbury station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as The Clere School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of the Ascension, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we do, step by step

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a single window, longer for several. Somewhere as small as Burghclere Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic isn’t too thick.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. The finish is dressed so it sits neatly against the stone or brick.

Preparing for the visit

  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work

Aftercare tips

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Look over the window mastic once a year
  • Ask the planning authority about consent for listed or conservation-area homes
  • Sort the mastic before the decorators arrive
  • Have rotten timber repaired before new mastic goes in

Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.

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

What we cannot put right

It helps to know what we cannot do:

  • Putty and glazing repairs
  • Decisions on consent for listed homes
  • Timber that has rotted

If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Questions from Burghclere Common

Do you cover Burghclere Common for sand mastic?

Yes, Burghclere Common is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Will you come out to Burghclere Common?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you offer different sealant colours?

Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.

Can sand mastic be painted?

Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.

Do I need permission for sand mastic on a listed building?

Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.

Do you take out the old sealant first?

Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

Should I use sand mastic or silicone?

It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames normally get a flexible sealant.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

What happens if it’s left?

Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. Older cottages and farmhouses around Burghclere Common can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
