Sand mastic in Milton Common, done properly

Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We’re often asked to deal with draughts and rain around sash boxes and gaps between timber frames and stone or brick, across sash and case windows, timber door frames and stone surrounds.

In a village or hamlet like Milton Common, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

All our work comes with our 12-month guarantee, wherever you are in Oxfordshire.

What happens on the day

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Somewhere as small as Milton Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

Preparing for the visit

  • Keep children and pets away from the work area
  • Tell us about any water getting in
  • For indoor joints, keep the area dry beforehand if you can

Advice

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Honest limits

New sealant can’t fix everything, and we’d rather say so up front. It will not solve:

  • Broken panes
  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Masonry that needs repairing

If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Surfaces we seal

What sand mastic looks like in Milton Common

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Adwell House (about 3.8 miles south-east) are a reminder that the area around Milton Common has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

In and around Milton Common, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Your questions about sand mastic in Milton Common

Will you come out to Milton Common?

Yes. Milton Common is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Is there a guarantee on sand mastic in Milton Common?

All our work, in Milton Common and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Are you fully insured?

Yes. Mr Mastic is fully insured.

Will it make a mess?

No. The area is protected while we work and cleaned up afterwards.

What is sand mastic?

It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.

Do you work for landlords and businesses?

Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

What we’re called out for in Milton Common

Paint, silicone or cement used over old mastic causes problems. They do not suit the joint and we normally remove them.

Common reasons people contact us include:

  • Gaps between timber frames and stone or brick
  • A silicone bead on a sash window that spoils the look
  • Wind and rain getting in round a sash window
  • Crumbling sand mastic round a window

If you live in an older home near Church of St Helen, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions to ask before you book

  • How much experience the applicator has
  • Is the old sealant removed completely?
  • Which colour the sealant will be
  • What product goes in the joint

Different surfaces, different methods

Brick reveals

An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

Tenement and terrace windows

Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.

What affects the cost of sand mastic

We do not publish a price list, because jobs vary so much. The quote depends on:

  • How many rooms, windows or areas are involved
  • Any working-time requirements on site
  • How much old sealant there is and how hard it is to remove
  • Which sealant suits the joint

Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • The rough size of the job
  • Pictures of the joints, sent by email
  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed

For a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
