Sand mastic in Skippers Hill

What happens if it’s left?

Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Skippers Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Every job is a little different, so we quote each one individually. 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.

About our sand mastic in Skippers Hill

On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead and we’ll explain which is best for yours. If you have old cement repairs round a window that have failed and mastic that needs renewing before redecorating, we can help, on tenement windows, period & listed homes and stone surrounds alike.

Around Skippers Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

There’s a 12-month guarantee on every job.

Is Skippers Hill in your area for sand mastic?

Yes, Skippers Hill is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.

Do you cover smaller places like Skippers Hill?

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

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

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

Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.

Can new sealant go over the old?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

The process

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. In a small place like Skippers Hill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at the surrounds with you and agree the joints to renew.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Before we arrive

  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access

Advice

Skippers Hill homes and the weather

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you let a flat or house near Crowborough station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Skippers Hill Manor School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of the Good Shepherd, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Get any rot dealt with first
  • Clear gutters so water does not pour onto the windows
  • Find out about consent before window work on a listed home
  • Don’t paint over the new mastic

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.

Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

What affects the quote in Skippers Hill

We quote each job individually. This is what makes a difference:

  • Which sealant suits the joint
  • How easy the joints are to reach
  • The old material and how stubborn it is
  • When we can work, for business premises

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Helping us quote

Before you ask for a quote, have a think about:

  • If it’s domestic, commercial or a hotel
  • Roughly how big the job is
  • Any previous sealing or DIY work
  • A few photos by email, if you can

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

If you’re 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 fails, we can still redo it.

What sealant work cannot fix

Some problems need a builder, plumber or other trade rather than us:

  • Planning or listed building consent (your local planning authority decides)
  • Timber that has rotted
  • Masonry that needs repairing

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