Sand mastic in Lamarsh, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. If you have crumbling sand mastic round a window and mastic round period door frames that has failed, we can help.
Around Lamarsh, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee in Lamarsh and across Essex.

Quotes for sand mastic in Lamarsh
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- How much there is to do
- Whether the work is at height
- How many rooms, windows or areas are involved
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
When you call or email, it’s useful to know:
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or email us.
FAQs for Lamarsh
Do you cover Lamarsh for sand mastic?
Yes. Our work covers London and the South East, and Lamarsh is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Do you work for landlords with property near Bures station?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later and we will give you an idea for your job.
How much does sand mastic cost in Lamarsh?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
How long will you be here?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
What we’re called out for in Lamarsh
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
These are the problems we’re asked about most:
- Mastic worn away on windows facing the weather
- Mastic that needs renewing before redecorating
- Cement or filler used on old window joints that has cracked
- Old sand mastic that has cracked, crumbled or fallen out
Homes close to Church of the Holy Innocents include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- What insurance they hold
- When the joint can take water or movement
- What guarantee comes with the work
- Which sealant they’ll use, and why
What sealant work cannot fix
We will always be straight with you, so here’s what sealant cannot fix:
- Masonry that needs repairing
- Timber that has rotted
- Sashes that need overhauling
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Period & listed homes
- Brick reveals
- Sash and case windows
- Tenement windows
- Timber door frames
- Stone surrounds
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Avoid heavy scraping on the mastic joint
- Inspect the joints round the windows every year or so
- Find out about consent before window work on a listed home
- Keep modern sealant off the mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.

What else we do in Lamarsh
Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Lamarsh can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows.

- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit

- Tell us about any water getting in

What sand mastic looks like in Lamarsh
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. With historic houses such as Gainsborough's House (about 3.7 miles north) nearby, there’s older building stock in the area around Lamarsh as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Bures station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
