About our sand mastic in Upper Halliford

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 and built up by hand. On period homes, it looks right where silicone wouldn’t. If you’re dealing with a silicone bead on a sash window that spoils the look and cracked mastic round a front door frame, we can help, whatever the surface.

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

Whatever the size of the job, you get the same 12-month guarantee in Upper Halliford and across Surrey.

Leave it or put it right?

Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Upper Halliford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

  • Homes, businesses and hotels

DIY versus a professional finish

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

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

What happens on the day

We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Upper Halliford, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by checking each surround and agreeing the joints to renew.
  2. We rake out the old mastic and clean the joint.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. We dress the surface so it sits neatly against the masonry.

Getting ready for the visit

  • Move anything stored near the joints
  • Mention any tricky access
  • Keep children and pets away from the work area

Sand mastic in Upper Halliford: local notes

Historic houses like Hampton Court Palace (about 4 miles east) are a reminder that the area around Upper Halliford has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For an older house near a landmark such as Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Upper Halliford station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Surface by surface

Period and listed homes

Period homes look their best with traditional materials.

Timber door frames

Doors face weather and wear and the mastic can crack early. We rake it out and renew it.

When something else is needed

Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Cracked or broken glass
  • Sashes that rattle, stick or won’t open
  • Timber that has rotted

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What we seal

  • Brick reveals
  • Tenement windows
  • Stone surrounds
  • Timber door frames

  • Period & listed homes

We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

When to call us in Upper Halliford

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.

Look out for these signs:

  • Weathered mastic on the most exposed windows
  • Gaps between timber frames and stone or brick
  • Patchy fillers round a sash window
  • Silicone on a period window that looks wrong

For site and facilities teams at buildings such as The Bishop Wand Church of England School, its window and door frames need their mastic kept sound, just like a home’s.
