How we handle sand mastic in Flowers Green
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you have old cement repairs round a window that have failed and gaps round a timber door in stone or brick, we can help, on stone surrounds, period & listed homes and tenement windows alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Flowers Green is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. In a small place like Flowers Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Questions from Flowers Green
I let a flat near Pevensey Bay station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover smaller places like Flowers Green?
Yes. Flowers Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you match the sealant colour?
We will 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?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Common problems we fix in Flowers Green
Rain on the window surround works into any crack and loosens it further. Exposed elevations generally fail first.
Look out for any of the following:
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
Horselunges Manor, about 3.4 miles west, is one of the historic houses in the wider area around Flowers Green, and older homes nearby need a sealant that suits their walls.

Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
How to look after the new joints
So the new joints stay in good condition:
- Do not run silicone over sand mastic
- Inspect the joints round the windows every year or so
- Keep sills and gutters clear so water drains away
- Leave the new mastic unpainted
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
For landlords and businesses
Letting agents and landlords in Flowers Green can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Windows and doors in Flowers Green
Historic houses like Horselunges Manor (about 3.4 miles west) are a reminder that the area around Flowers Green has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Pevensey Bay station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Herstmonceux Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
