Sand mastic in Chilmington Green, done properly

A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you’re dealing with old cement repairs round a window that have failed and old sand mastic that has cracked, crumbled or fallen out, we can put it right, on period & listed homes, brick reveals and timber door frames alike.

Somewhere as small as Chilmington Green, older homes often have timber frames set in stone or brickwork. 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, in Chilmington Green and everywhere else we cover.

Chilmington Green: your questions answered

Will you come out to Chilmington Green?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you do sand mastic in Chilmington Green?

Yes, Chilmington Green is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

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

Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.

How long does sand mastic take to go off?

A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.

Can new sealant go over the old?

No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Which is right for my windows, sand mastic or modern sealant?

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.

Will you leave a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Are you fully insured?

Yes. We are fully insured.

What we are called out for in Chilmington Green

Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.

These are the problems we’re asked about most:

  • A silicone bead on a sash window that spoils the look
  • Gaps where the frame meets the masonry
  • Wind and rain getting in round a sash window
  • Cement or filler used on old window joints that has cracked

Schools such as Great Chart Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Before booking anyone

  • Who does the work, and how experienced they are
  • Whether all the old sealant comes out first
  • How long to leave it before use
  • The length of the guarantee

Our hiring checklist

Aftercare tips

To keep the joints looking good and working properly:

  • Look over the window mastic once a year
  • Avoid patching sand mastic with silicone
  • Do not paint over the new mastic
  • Avoid heavy scraping on the mastic joint

Make sure water drains away from the window surround. Constant wetting wears the mastic faster.

Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

Frames and glazing around Chilmington Green

Rainfall in the South East is lower than in much 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 Godinton House (about 1.9 miles north) nearby, there’s older building stock in the area around Chilmington Green 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.

Letting a property close to Ashford International station? Then any sash windows need sound mastic to keep draughts and rain out. In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Why it’s worth doing now in Chilmington Green

New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. Older cottages and farmhouses around Chilmington Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

What you get with us

  • ARBOMaster approved applicator
  • Anti-fungal silicone where joints get wet

Work for landlords, hotels and businesses

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

If you’ve already had a go yourself, that is fine. We cut it out and start again.
