Sand mastic near Taplow

Sand mastic in Taplow, done properly

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. Common call-outs are for mastic round period door frames that has failed and draughts and rain around sash boxes, across sash and case windows, stone surrounds and period & listed homes.

Around Taplow, 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.

All of our work is guaranteed for twelve months, in Taplow and everywhere else we cover.

Common problems we fix in Taplow

Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.

Look out for these signs:

  • Gaps where the frame meets the masonry
  • Tired mastic found when preparing windows for paint
  • Silicone on a period window that looks wrong
  • Old sand mastic that has cracked, crumbled or fallen out

Schools such as St Nicolas' Church of England Combined School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What your quote should include

  • How the surfaces are prepared before sealing
  • How long to leave it before use
  • Whether VAT is included
  • Whether they seal over old material or remove it

How to choose a mastic man

What affects the cost of sand mastic

Your quote is based on your job. We take into account:

  • Any working-time requirements on site
  • How many rooms, windows or areas are involved
  • The old material and how stubborn it is
  • Access and height

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. You’ll know the price before we begin.

What to tell us for a quote

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

  • If someone has resealed it before
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • Roughly how big the job is

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.

Can I do it myself?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

The process

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Taplow, the journey is planned in advance: 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 check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

Before we arrive

  • Let us know about earlier repairs to the joints
  • On commercial sites, let us know about site rules
  • Tell us if parking is tricky

Advice

Different surfaces, different methods

Stone surrounds

Sand mastic sits naturally against stone. The finish blends with the masonry.

Timber door frames

Sand mastic is used round timber door frames too. We renew it the same way as on windows.

Aftercare tips

Simple care keeps the joints in good condition. Our advice:

  • Avoid heavy scraping on the mastic joint
  • Ask us before painting near the mastic
  • Clear gutters so water doesn’t pour onto the windows
  • Sort the mastic before the decorators arrive

Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.

Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.

What sand mastic looks like in Taplow

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 Cliveden (about 1.8 miles north) are a reminder that the area around Taplow has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

For landlords with property near Taplow station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Nicolas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
