Sand mastic for Stanford in the Vale homes and businesses

How we handle sand mastic in Stanford in the Vale

Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. Common call-outs are for patchy fillers round a sash window and open joints round the window box, across stone surrounds, tenement windows and period & listed homes.

Houses in smaller places like Stanford in the Vale can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.

Every job comes with our 12-month guarantee, wherever you are in Oxfordshire.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Make sure water runs off the sill
  • Have rotten timber repaired before new mastic goes in
  • Do not run silicone over sand mastic
  • Check with your local planning authority if your home is listed

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.

It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

When to call us in Stanford in the Vale

Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.

Any of these means the joints need attention:

  • Tired mastic found when preparing windows for paint
  • A silicone bead on a sash window that spoils the look
  • Failed mastic on an exposed elevation
  • Mastic round period door frames that has failed

Managing a site like Stanford in the Vale Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

How to choose a mastic man

Your questions about sand mastic in Stanford in the Vale

What guarantee comes with sand mastic in Stanford in the Vale?

Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.

Do you cover smaller places like Stanford in the Vale?

Yes, Stanford in the Vale is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Will it make a mess?

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

Where do you work from?

We are based in Crawley, and we work across South East England, London and Scotland.

Can new sealant go over the old?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

When will the new mastic be hard?

Not right away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Can I choose the sealant colour?

Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.

Why act early in Stanford in the Vale

An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. In an older home around Stanford in the Vale, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before work begins.

Why us?

  • Old sealant always removed completely
  • Anti-fungal silicone where joints get wet
  • Tidy, careful work
  • An ARBOMaster approved applicator

Quotes for sand mastic in Stanford in the Vale

We don’t publish a price list, because jobs vary so much. What we look at:

  • Which sealant suits the joint
  • The number of rooms or windows
  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Helping us quote

Before you ask for a quote, have a think about:

  • What’s wrong with the joints now
  • The address or postcode of the job
  • How many joints, rooms or windows are involved
  • If it’s domestic, commercial or a hotel

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

What we do, step by step

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. All told, the work takes a few hours for a single window, longer for several. For a job in Stanford in the Vale, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Before we arrive

  • Mention any tricky access
  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before

Advice

DIY versus a professional finish

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.

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 does not work out, we can still put it right.

Sand mastic in Stanford in the Vale: local notes

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Longworth House (about 4.7 miles north-east) nearby, there’s older building stock in the area around Stanford in the Vale as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

In the older streets around Church of St Denys, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
