Sand Mastic in Great Notley
Problem with your window and door surrounds in Great Notley? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

Sand mastic for homes and businesses in Great Notley
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on timber door frames, sash and case windows and stone surrounds, and the jobs we see most are mastic worn away on windows facing the weather and old sand mastic that has cracked, crumbled or fallen out.
Many houses in smaller places like Great Notley have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
All our work comes with our one-year guarantee.

What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Any mould that needs treating
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Other services in Great Notley
Do you need sand mastic in Great Notley?
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
These are the problems we’re asked about most:
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
Managing a site like White Court School? Then its window and door frames need their mastic kept sound, just like a home’s.

What does sand mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What sand mastic looks like in Great Notley
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Braintree station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as The Church in Great Notley, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why it’s worth doing now in Great Notley
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In a smaller place like Great Notley, 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 play a part, and we’ll explain the quote if you ask.
