How we handle sand mastic in Ascott d'Oyley

Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Common call-outs are for failed mastic on an exposed elevation and mastic that needs renewing before redecorating, across period & listed homes, stone surrounds and timber door frames.

Homes in small places like Ascott d'Oyley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

Your job is guaranteed for a year, as with all our work.

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Ascott d'Oyley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • Mention any sign-in or site rules at work premises
  • Tell us if parking is tricky

Do you need sand mastic in Ascott d'Oyley?

Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they normally need raking out.

Keep an eye out for any of the following:

  • Window mastic to renew ahead of painting
  • Draughts and rain around sash boxes
  • A silicone bead on a sash window that spoils the look
  • Weathered mastic on the most exposed windows

In the older streets around Church of the Holy Trinity, the joint between an old wall and a newer frame is normally the first place rain gets in.

  • Whether the sealant suits the joint

Ascott d'Oyley homes and the weather

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Minster Lovell Hall (about 4.3 miles south) are a reminder that the area around Ascott d'Oyley 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.

Rented homes near Ascott-Under-Wychwood station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Your questions about sand mastic in Ascott d'Oyley

Will you come out to Ascott d'Oyley?

Yes, Ascott d'Oyley is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is Ascott d'Oyley in your area for sand mastic?

Yes, Ascott d'Oyley is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.

Do you work for letting agents?

Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.

Do you offer different sealant colours?

Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.

Where do you work from?

Our base is Crawley. We work across South East England, London and Scotland.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Can you seal over the old sealant?

No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Is it possible to take out silicone and use sand mastic instead?

Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.

Keeping the joints in good condition

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

  • Avoid heavy scraping on the mastic joint
  • Check with your local planning authority if your home is listed
  • Look over the window mastic once a year
  • Renew mastic before redecorating the windows

Make sure water drains away from the window surround. Constant wetting wears the mastic faster.

An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.

Leave it or put it right?

Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like Ascott d'Oyley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
