Sand mastic for homes and businesses in Broadford
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you are dealing with mastic that needs renewing before redecorating and draughts and rain around sash boxes, we can put it right, whatever the surface.
Around Broadford, 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.
Every job comes with our one-year guarantee.

What sand mastic looks like in Broadford
London and the South East are among 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 Loseley Park (about 1.4 miles west) nearby, there’s older building stock in the area around Broadford 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.
If you look after a building such as Shalford Infant School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Shalford station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Common questions in Broadford
Do you cover smaller places like Broadford?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Shalford station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we’ll explain why.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Where are you based?
We work from Crawley. Our applicators cover Broadford.
How much does sand mastic cost in Broadford?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Timber that has rotted
- Damaged stone surrounds
- Decisions on consent for listed homes
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
- Timber door frames
- Stone surrounds
- Sash and case windows
- Period & listed homes
- Brick reveals
- Tenement windows
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
- Keep sills and gutters clear so water drains away
- Have rotten timber repaired before new mastic goes in
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

What we are called out for in Broadford
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Most people get in touch after spotting something like this:
- Old cement repairs round a window that have failed
- Mastic that needs renewing before redecorating
- Modern sealant on a period surround
- Crumbling sand mastic round a window
Homes close to St Michael include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
