How we handle sand mastic in Faulkbourne
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. If you have old sand mastic that has cracked, crumbled or fallen out and open joints round the window box, we can help.
Homes in small places like Faulkbourne often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You get a one-year guarantee, the same in Faulkbourne as everywhere else we work.

Common questions in Faulkbourne
Is Faulkbourne in your area for sand mastic?
Yes. We work across London and the South East, and Faulkbourne is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Can you help a landlord with a rental near White Notley station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Where are you based?
We work from Crawley. We cover Faulkbourne and the rest of Essex.
Can I choose the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
What affects the quote in Faulkbourne
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Any mould that needs treating
- The type of sealant required
- Any working-time requirements on site
- The size of the job
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- The address or postcode of the job
- Roughly how big the job is
To get a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. We will send you a clear quote before any work starts.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
What sealant work can’t fix
It helps to know what we cannot do too:
- Broken panes
- Crumbling stone or brickwork round the window
- Timber that has rotted
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Why it’s worth doing now in Faulkbourne
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Faulkbourne can have timber 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 agree the price before starting.
