About our sand mastic in Eastry

We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you’re dealing with gaps where the frame meets the masonry and modern sealant on a period surround, we can help, on timber door frames, tenement windows and sash and case windows alike.

In smaller places like Eastry, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.

You get a one-year guarantee, the same in Eastry as everywhere else we work.

DIY versus a professional finish

If you are 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.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

How it works

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several, and the area is left clean. For a job in Eastry, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by checking each surround and agreeing the joints to renew.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic isn’t too thick.
  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.

How to prepare

  • Tell us if parking is tricky
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any sign-in or site rules at work premises

What sand mastic looks like in Eastry

Historic houses like Goodnestone Park (about 3.4 miles west) are a reminder that the area around Eastry has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

For site and facilities teams at buildings such as Eastry Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Sandwich station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Leave it or put it right?

Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In a smaller place like Eastry, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Common questions in Eastry

Do you work for landlords with property near Sandwich station?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Can you do sand mastic in Eastry?

Yes, Eastry is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.

How long does sand mastic take?

That depends on how much there is to do, but most jobs take a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint.

Should I try DIY first?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Do you work for hotels and businesses?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Ask a joiner to look at soft timber first
  • Make sure water runs off the sill
  • Check the mastic when you check the paintwork
  • Avoid patching sand mastic with silicone

Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.

Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.

How we quote for sand mastic

Every job gets its own quote. This is what makes a difference:

  • The number and length of the joints
  • Any mould that needs treating
  • Any working-time requirements on site
  • Whether old sealant or filler has to be cut out

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

What we need to know

When you call or email, it’s useful to know:

  • Roughly how big the job is
  • Where the job is, and your postcode
  • Access, such as stairs, a lift or height
  • If someone has resealed it before
