Sand mastic in Barrow Hill: local notes

Barrow Hill is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.

Managing a site like Mersea Island School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic for homes and businesses in Barrow Hill

Across Barrow Hill, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you’re dealing with mastic dropping out of the joint and wind and rain getting in round a sash window, we can help, on timber door frames, stone surrounds and tenement windows alike.

Somewhere as small as Barrow Hill, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Each job carries a 12-month guarantee, large or small.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Look over the window mastic once a year
  • Sort the mastic before the decorators arrive
  • Have rotten timber repaired before new mastic goes in
  • Do not paint over the new mastic

Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.

Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.

How the visit works

The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job generally takes a few hours for a single window, longer for several, and we tell you how long to leave it before we go. For a village or hamlet like Barrow Hill, 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. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

Before we arrive

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • Let us know about parking restrictions

Do you need sand mastic in Barrow Hill?

Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.

Look out for any of the following:

  • Failed mastic on an exposed elevation
  • Patchy fillers round a sash window
  • Draughts and rain around sash boxes
  • Cracked mastic round a front door frame

For landlords with property near Wivenhoe station, any sash windows need sound mastic to keep draughts and rain out.

10 questions to ask before booking

Why act early in Barrow Hill

A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around Barrow Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before any work starts.

Questions from Barrow Hill

Does living near the coast affect sand mastic in Barrow Hill?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.

Will you come out to Barrow Hill?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you have insurance?

Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

How long does sand mastic take?

That depends on the amount of work, but as a guide it takes a few hours for a single window, longer for several. We’ll tell you when we quote.

Can old silicone round a sash window be swapped for sand mastic?

Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.

What’s sand mastic made of?

Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.

Do you work for letting agents?

Yes. We work in homes, commercial premises and hotels, and we are fully insured.

Timber door frames

Sand mastic is used round timber door frames too. We renew it the same way as on windows.

Period and listed homes

A traditional finish suits a period property, and sand mastic is one of them.

Call for a quick quote. What matters most is:

  • How many rooms, windows or areas are involved
  • The old material and how stubborn it is
  • Whether the work is at height
  • Which sealant suits the joint

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What to tell us for a quote

Photos help, but a description is a good start. Try to tell us:

  • Whether it has been sealed before
  • Any access issues, like height or stairs
  • Roughly how big the job is
  • The address or postcode of the job

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, phone 0345 464 0079 or email us.
