How we handle sand mastic in Norton

Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. If you’re dealing with old sand mastic that has cracked, crumbled or fallen out and a silicone bead on a sash window that spoils the look, we can put it right.

Homes in small places like Norton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

Every job comes with a 12-month guarantee, wherever you are in East Sussex.

What sand mastic looks like in Norton

Norton is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.

If you look after a building such as UTC@Harbourside, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to choose a mastic man

Norton: your questions answered

Does living near the coast affect sand mastic in Norton?

Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.

Is Norton within the area you cover?

Yes, Norton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is it possible to paint over sand mastic?

The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will talk you through it.

When will the new mastic be hard?

A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.

What’s sand mastic made of?

Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.

How much does sand mastic cost in Norton?

Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

Will it make a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Is consent needed for window work on a listed home?

Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Why deal with it now?

A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a small place like Norton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

How the visit works

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. For a village or hamlet like Norton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Tell us about any previous sealing or DIY attempts
  • On commercial sites, let us know about site rules
  • Mention any leaks or damp you’ve noticed

Advice
