The process

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Binscombe, 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. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

Getting ready for the visit

  • Tell us about any water getting in
  • Mention any parking rules near the property
  • Where the joints are inside, avoid wetting them before we arrive

Advice

When to call us in Binscombe

Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.

Most people get in touch when they notice something like this:

  • Tired mastic found when preparing windows for paint
  • Failed mastic on an exposed elevation
  • Gaps round a timber door in stone or brick
  • Modern sealant on a period surround

In the older streets around St John the Evangelist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions to ask before booking

  • The length of the guarantee
  • Whether the sealant suits the joint
  • How hidden problems are handled
  • What the quote includes, VAT included or not

10 questions to ask before you book

What the job involves on each surface

Sash and case windows

On a sash window, the mastic joint shows on the outside so we finish it carefully.

Brick reveals

Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.

When it isn’t the sealant

It helps to know what we cannot do too:

  • Damaged stone surrounds
  • Timber that has rotted
  • Sash cords, weights and draught-proofing of the sashes

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

What we seal

  • Stone surrounds
  • Timber door frames
  • Period & listed homes
  • Brick reveals
  • Sash and case windows
  • Tenement windows

Frames and glazing around Binscombe

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. Historic houses like Loseley Park (about 0.7 miles north-east) are a reminder that the area around Binscombe has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Schools such as Loseley Fields Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Farncombe station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Questions from Binscombe

Is Binscombe in your area for sand mastic?

Yes. Our work covers London and the South East, and Binscombe is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Is Binscombe 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.

Can I add another job to the visit?

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

How do I get a quote for sand mastic in Binscombe?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Do you work for hotels and businesses?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.

Can old silicone round a sash window be swapped for sand mastic?

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

What’s sand mastic made of?

Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.

DIY sealant or a professional job?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

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

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Leave the new mastic unpainted
  • Check with your local planning authority if your home is listed
  • Go gently near the mastic when preparing windows
  • Inspect the joints round the windows every year or so

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.

It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
