Sand mastic for homes and businesses in Faygate

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on period & listed homes, tenement windows and sash and case windows, and the jobs we see most are cement or filler used on old window joints that has cracked and window mastic to renew ahead of painting.

Around Faygate, 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.

Each job carries a 12-month guarantee.

Signs you need sand mastic in Faygate

Timber frames move with the seasons. The movement cracks the mastic little by little.

Any of these means the joints need attention:

  • Mastic that needs renewing before redecorating
  • Mastic worn away on windows facing the weather
  • Mastic round period door frames that has failed
  • Mastic dropping out of the joint

Letting a property close to Faygate station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Before booking anyone

  • How the joint is cleaned and prepared
  • What product goes in the joint
  • Is the old sealant removed completely?
  • What the quote includes, VAT included or not

Our hiring checklist

Looking after it afterwards

Looking after new joints is easy:

  • Check the mastic when you check the paintwork
  • Sort the mastic before the decorators arrive
  • Do not paint over the new mastic
  • Avoid heavy scraping on the mastic joint

Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.

Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Different surfaces, different methods

Sash and case windows

The mastic round a sash window is on show, so a neat, even finish matters.

Tenement and terrace windows

Upper-floor windows need access planning. Let us know the floor and we’ll confirm access.

What we do, step by step

Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours per window, depending on the condition of the joints. In a small place like Faygate, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  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.

Preparing for the visit

  • Mention any parking rules near the property
  • Tell us about any previous sealing or DIY attempts
  • Clear the area around the work

What sand mastic looks like in Faygate

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.

If you live in an older home near St Francis' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Holy Trinity CofE Secondary School, larger buildings have plenty of frames, and the mastic around each one ages.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.

Leave it or put it right?

Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Where a wall is exposed, as many are in small places like Faygate, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
