About our sand mastic in Stanwell Moor

Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. Typical jobs include mastic round period door frames that has failed and open joints round the window box, on brick reveals, period & listed homes and sash and case windows.

Mastic can only go onto a dry, clean joint, so window work in Stanwell Moor is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Your questions about sand mastic in Stanwell Moor

Is Stanwell Moor in your area for sand mastic?

Yes. We work across London and the South East, and Stanwell Moor is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.

Do you cover smaller places like Stanwell Moor?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Is it messy?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Keep sills and gutters clear so water drains away
  • Find out about consent before window work on a listed home
  • Do not run silicone over sand mastic
  • Inspect the joints round the windows every year or so

When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.

Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.

Frames and glazing around Stanwell Moor

Historic houses like Frogmore House (about 4.1 miles west) are a reminder that the area around Stanwell Moor 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For site and facilities teams at buildings such as Town Farm Primary School & Nursery, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What the job involves on each surface

Stone surrounds

Stone openings are rarely perfectly straight, so the gap is not the same all the way round. We shape it by hand to follow the stone.

Tenement and terrace windows

Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.

How the visit works

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. After that, the work takes anything from a few hours to a full day, depending on how many windows. In a small place like Stanwell Moor, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Let us know about parking restrictions
  • Let us know if you’ve seen damp or leaks
  • Keep children and pets away from the work area

Advice

Why act early in Stanwell Moor

Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Stanwell Moor, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.

Do you need sand mastic in Stanwell Moor?

Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.

The most common problems we see are:

  • Failed mastic on an exposed elevation
  • Mastic dropping out of the joint
  • Tired mastic found when preparing windows for paint
  • Patchy fillers round a sash window

For landlords with property near Heathrow Terminal 5 Rail station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
