Sand mastic in Matching Green

Sand mastic in Matching Green

Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. We are often asked to deal with a silicone bead on a sash window that spoils the look and old cement repairs round a window that have failed, on timber door frames, period & listed homes and tenement windows.

Somewhere as small as Matching Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Quotes for sand mastic in Matching Green

The quote reflects the job in front of us. We look at:

  • The type of sealant required
  • The size of the job
  • The old material and how stubborn it is

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Asking for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • If it’s domestic, commercial or a hotel
  • Where the property is
  • What’s wrong with the joints now
  • How we’d reach the joints

To get 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.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. For a village or hamlet like Matching Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

Preparing for the visit

  • Tell us if parking is tricky
  • Tell us about access, such as stairs, a lift or high-level joints
  • Plan for the work area to be out of bounds to pets and children

How to get a quote

Getting a quote is simple: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

Advice

Looking after it afterwards

After the cure time, these simple habits help:

  • Ask a joiner to look at soft timber first
  • Check with your local planning authority if your home is listed
  • Check the mastic when you check the paintwork
  • Go gently near the mastic when preparing windows

When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

Do you need sand mastic in Matching Green?

Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.

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

  • Cracked mastic round a front door frame
  • Gaps between timber frames and stone or brick
  • Draughty sash windows at the surround
  • Mastic that needs renewing before redecorating

For landlords with property near Sawbridgeworth station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

FAQs for Matching Green

Do you work for landlords with property near Sawbridgeworth station?

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

Will you come out to Matching Green?

Yes, Matching Green is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

What information do you need?

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

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Can you seal over the old sealant?

No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

What does sand mastic cost?

Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.

How long does sand mastic take to go off?

The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.

Should I check with the council before work on a listed or conservation-area home?

Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.

Surface by surface

Timber door frames

Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.

Stone surrounds

Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.

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 is the traditional material and blends with the stone or brick. In a small place like Matching Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

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. Your quote takes all of that into account.

Frames and glazing around Matching Green

With historic houses such as Barrington Hall (about 4.1 miles north) nearby, there’s older building stock in the area around Matching Green as well as newer homes. 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For an older house near a landmark such as Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
