Sand mastic near Eastling

What the job involves on each surface

Period and listed homes

Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

Sand mastic for homes and businesses in Eastling

If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Typical jobs include tired mastic found when preparing windows for paint and draughty sash windows at the surround, on brick reveals, period & listed homes and stone surrounds.

In a village or hamlet like Eastling, older cottages and farmhouses often have timber windows set in stone or brick. 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.

What sand mastic looks like in Eastling

Historic houses like Belmont House and Gardens (about 1.4 miles east) are a reminder that the area around Eastling 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. 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 Eastling Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints

So the new joints stay in good condition:

  • Have rotten timber repaired before new mastic goes in
  • Make sure water runs off the sill
  • Ask us before painting near the mastic
  • Inspect the joints round the windows every year or so

Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.

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

Common questions in Eastling

Do you cover smaller places like Eastling?

Yes. Eastling is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you help a landlord with a rental near Teynham station?

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

Will you leave a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Do you do commercial work?

Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.

Should I use sand mastic or silicone?

For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.

How long does sand mastic take?

As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll say how long yours will take.

When will the new mastic be hard?

It takes a while. It skins first and hardens fully later and we will give you an idea for your job.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Why deal with it now?

Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Eastling, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

How the visit works

We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere like Eastling needs a little journey planning: 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. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

How to prepare

  • Move anything stored near the joints
  • Mention any parking rules near the property
  • Let us know about stairs, lifts or work at height

Advice

Common problems we fix in Eastling

Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.

If you can see any of these, it’s time to have the joints looked at:

  • Mastic round period door frames that has failed
  • Mastic dropping out of the joint
  • Mastic that needs renewing before redecorating
  • Open joints round the window box

If you let a flat or house near Teynham station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Choosing a sealant specialist

What affects the cost of sand mastic

The price is agreed before any work begins. It’s based on:

  • How much old sealant there is and how hard it is to remove
  • Mould in or behind the old joints
  • The number and length of the joints
  • The type of sealant required

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • The type of property
  • Any previous sealing or DIY work
  • Any access issues, like height or stairs
  • The rough size of the job

Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand.

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Sealing over old silicone is the commonest DIY error. 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.
