How we handle sand mastic in Deane

For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, period & listed homes and tenement windows, and people most often call us about modern sealant on a period surround and mastic round period door frames that has failed.

In a village or hamlet like Deane, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Why it’s worth doing now in Deane

Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Around Deane, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

What we cannot put right

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Whether work needs listed building consent
  • Broken panes
  • Crumbling stone or brickwork round the window

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Common questions in Deane

Can you do sand mastic in Deane?

Yes. Our work covers London and the South East, and Deane is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.

Do you cover smaller places like Deane?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you do several jobs on one visit?

Of course. Doing several areas at once is normally more efficient.

Should I check with the council before work on a listed or conservation-area home?

Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.

Can sand mastic be painted?

It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.

Will you leave a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before resealing.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

Frames and glazing around Deane

The South East is one of 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 let a flat or house near Overton station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Quotes for sand mastic in Deane

We quote each job individually. These are the things that affect it:

  • How much there is to do
  • Which sealant suits the joint
  • Working hours on commercial sites
  • Any mould that needs treating

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What to tell us for a quote

You do not need to know the technical terms. Just tell us:

  • What’s wrong with the joints now
  • How we’d reach the joints
  • A few photos by email, if you can
  • Where the property is

For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Don’t paint over the new mastic
  • Find out about consent before window work on a listed home
  • Clear gutters so water does not pour onto the windows
  • Have rotten timber repaired before new mastic goes in

Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

What we are called out for in Deane

Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.

Look out for these signs:

  • Old sand mastic that has cracked, crumbled or fallen out
  • Window mastic to renew ahead of painting
  • Weathered mastic on the most exposed windows
  • Modern sealant on a period surround

Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

How the visit works

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Deane, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about earlier repairs to the joints
