Sand mastic for Flackley Ash homes and businesses

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Sand mastic in Flackley Ash

For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with silicone on a period window that looks wrong and tired mastic found when preparing windows for paint, across stone surrounds, period & listed homes and brick reveals.

In a village or hamlet like Flackley Ash, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Our work is backed for twelve months.

How the visit works

We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job usually takes a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. Somewhere like Flackley Ash needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

How to prepare

  • Move anything stored near the joints
  • Keep children and pets away from the work area
  • Try not to wet indoor joints just before the visit

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Cracked or broken glass
  • Sash cords, weights and draught-proofing of the sashes
  • Decayed frames that need repair

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

Surfaces we seal

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

Surface by surface

Brick reveals

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

Tenement and terrace windows

Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.

Windows and doors in Flackley Ash

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Lamb House (about 3.2 miles south-east) are a reminder that the area around Flackley Ash 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.

For an older house near a landmark such as The Parish Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Rye station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Peasmarsh Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Do the sealants smell?

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. We agree the price before any work begins.

Do you offer different sealant colours?

Are you an approved applicator?

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

How we quote for sand mastic

The price is agreed before any work begins. It’s based on:

  • How easy the joints are to reach
  • The type of sealant required

Why it’s worth doing now in Flackley Ash

Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Around Flackley Ash, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
