Sand mastic in Home Farm, done properly
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Typical jobs include open joints round the window box and cracked mastic round a front door frame, across stone surrounds, brick reveals and sash and case windows.
Homes in small places like Home Farm often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, it’s backed by our one-year guarantee in Home Farm and across Bracknell Forest.

Home Farm homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Bracknell, which Home Farm is part of, is one of England’s post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
If you let a flat or house near Bracknell station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Michael and St Mary Magdalene's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Wooden Hill Primary and Nursery School, its window and door frames need their mastic kept sound, just like a home’s.

The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. Somewhere as small as Home Farm, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Keep children and pets away from the work area

Advice
What affects the quote in Home Farm
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- How many areas need sealing
- The old material and how stubborn it is
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- The problem you’ve noticed
- Where the property is
- How we’d reach the joints
We quote each job on its own. Simply call 0345 464 0079 or drop us an email and describe the job, and photos are welcome.
Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Home Farm can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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 we need extra access for height. Your quote takes all of that into account.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What sealant work cannot fix
Sealant isn’t the answer to every problem, and we will tell you before work begins. It won’t solve:
- Crumbling stone or brickwork round the window
- Sashes that need overhauling
- Whether work needs listed building consent
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Home Farm: your questions answered
Can you help a landlord with a rental near Bracknell station?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover smaller places like Home Farm?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
