Timber door frames
Round a period front door, sand mastic gives the right look.
Sand mastic in Four Elms, done properly
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We work on period & listed homes, tenement windows and sash and case windows, and the jobs we see most are old cement repairs round a window that have failed and weathered mastic on the most exposed windows.
In a village or hamlet like Four Elms, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Combining jobs into one visit usually makes better use of the time than several visits. We’ll give you a clear quote for the lot.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- If someone has resealed it before
- Pictures of the joints, sent by email
- How we’d reach the joints
- The address or postcode of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.
When to call us in Four Elms
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Most people get in touch after spotting one of these:
- Draughty sash windows at the surround
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
For an older house near a landmark such as Congregational Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How it works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. For a village or hamlet like Four Elms, the journey is planned in advance: 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.

- We rake out the old mastic and clean the joint.

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: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Your questions about sand mastic in Four Elms
Do you cover smaller places like Four Elms?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Edenbridge station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How long does the job take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. We’ll confirm how long when we quote.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Damaged stone surrounds
- Sashes that rattle, stick or will not open
- Rotten sashes, sills or window boxes (a joiner’s job)
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
Where we work in Four Elms
- Period & listed homes
- Sash and case windows
- Timber door frames
- Stone surrounds
- Tenement windows
- Brick reveals
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Four Elms, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear quote before any work starts.
Why book with us
- Homes, businesses and hotels
- Any old sealant cut out fully, not covered over
- Arbo and Everbuild products
- A 12-month guarantee on all work

Sand mastic in Four Elms: local notes
With historic houses such as Chartwell (about 2 miles north) nearby, there’s older building stock in the area around Four Elms as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Four Elms Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Edenbridge station, older sash windows in a rental need their mastic kept sound to keep the weather out.
