Leave it or put it right?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In a smaller place like East Malling, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Sand mastic in East Malling
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. If you have tired mastic found when preparing windows for paint and open joints round the window box, we can put it right, on sash and case windows, timber door frames and period & listed homes alike.
In smaller places like East Malling, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Each job carries a 12-month guarantee, large or small.

Windows and doors in East Malling
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. Historic houses like Starkey Castle (about 4.9 miles north) are a reminder that the area around East Malling 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’s traditional sand mastic.
Schools such as St James the Great Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Is East Malling within the area you cover?
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.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in East Malling.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic can sit properly.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll say how long yours will take.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
