How we handle sand mastic in Yelsted

Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you have cracked mastic round a front door frame and mastic that needs renewing before redecorating, we can help, on tenement windows, brick reveals and sash and case windows alike.

Outdoor sealant needs dry, clean surfaces, so work on frames around Yelsted is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What sealant work cannot fix

A few problems are outside what sealant work can do:

  • Sash cords, weights and draught-proofing of the sashes
  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Masonry that needs repairing

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

FAQs for Yelsted

Will you come out to Yelsted?

Yes, Yelsted is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you cover Yelsted for sand mastic?

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

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Where are you based?

We’re based in Crawley, and we cover South East England, London and all of Scotland.

Is consent needed for window work on a listed home?

It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.

When will the new mastic be hard?

It skins over fairly quickly but takes longer to harden fully. We’ll explain what to expect before we leave.

Do the sealants smell?

Some sealants have a smell while they cure, but it fades. Opening a window helps.

Do you work for landlords and businesses?

Yes. We work for householders, landlords, letting agents, businesses and hotels in Yelsted.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. A few tips:

  • Leave the new mastic unpainted
  • Renew mastic before redecorating the windows
  • Avoid patching sand mastic with silicone
  • Ask the planning authority about consent for listed or conservation-area homes

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.

Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

Yelsted homes and the weather

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Rented homes near Rainham (Kent) station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like St Augustine of Canterbury Catholic Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
