Sand mastic near Nazeing

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a single window, longer for several, including the tidy-up. For a village or hamlet like Nazeing, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, we look at the surrounds with you and agree what needs doing.
  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. The mastic is mixed, pressed into the joint by hand and shaped.
  5. We dress the surface so it sits neatly against the masonry.

Before we arrive

  • Tell us if parking is tricky
  • Move anything stored near the joints
  • For business premises, tell us about site rules or sign-in

Advice

Sand mastic in Nazeing

Across Nazeing, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. Common call-outs are for draughts and rain around sash boxes and silicone on a period window that looks wrong, on stone surrounds, tenement windows and period & listed homes.

Homes in small places like Nazeing 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.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Different surfaces, different methods

Stone surrounds

Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.

Sash and case windows

The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.

When something else is needed

Before you book, it’s worth knowing the limits too:

  • Timber that has rotted
  • Broken panes
  • Sashes that rattle, stick or will not open

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Surfaces we seal

  • Timber door frames
  • Stone surrounds
  • Sash and case windows
  • Tenement windows
  • Period & listed homes
  • Brick reveals

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Look over the window mastic once a year
  • Go gently near the mastic when preparing windows
  • Don’t paint over the new mastic
  • Clear gutters so water doesn’t pour onto the windows

Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.

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

Frames and glazing around Nazeing

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.

Schools such as Water Lane Primary Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Roydon station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Work for landlords, hotels and businesses

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.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

What happens if it’s left?

Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. Around Nazeing, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
