Sand mastic in Fringford

Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. We work on tenement windows, period & listed homes and stone surrounds, and people most often call us about mastic round period door frames that has failed and modern sealant on a period surround.

Somewhere as small as Fringford, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

There’s a 12-month guarantee on every job.

When to call us in Fringford

Rain on the window surround works into any crack and loosens it further. Exposed elevations normally fail first.

It’s worth asking for a quote if you see:

  • Mastic worn away on windows facing the weather
  • Window mastic to renew ahead of painting
  • Cracked mastic round a front door frame
  • A silicone bead on a sash window that spoils the look

Letting a property close to Bicester North station? Then any sash windows need sound mastic to keep draughts and rain out.

Choosing a sealant specialist

What happens on the day

Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to a full day, depending on how many windows. In a small place like Fringford, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

Before we arrive

  • Mention if the joints have been sealed before
  • Try not to wet indoor joints just before the visit
  • On commercial sites, let us know about site rules

Advice

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Ask a joiner to look at soft timber first
  • Find out about consent before window work on a listed home
  • Go gently near the mastic when preparing windows
  • Keep modern sealant off the mastic

Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.

Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

What sand mastic looks like in Fringford

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.

For an older house near a landmark such as Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Fringford Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Common questions in Fringford

I let a flat near Bicester North station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.

Is Fringford in your area for sand mastic?

Yes, Fringford is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.

Do I need permission for sand mastic on a listed building?

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

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can new sealant go over the old?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Do you work for hotels and businesses?

Yes. We have worked for hotels, offices and other businesses and we are fully insured.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Leave it or put it right?

New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Older cottages and farmhouses around Fringford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
