How we handle sand mastic in Hill Green
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. We work on timber door frames, tenement windows and period & listed homes, and the jobs we see most are a silicone bead on a sash window that spoils the look and gaps between timber frames and stone or brick.
Homes in small places like Hill Green 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.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. For a village or hamlet like Hill Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear items away from the joints we are working on
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

- A silicone bead on a sash window that spoils the look

Windows and doors in Hill Green
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. Historic houses like Audley End House (about 4.2 miles north-east) are a reminder that the area around Hill 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.
Schools such as Clavering Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary and St Clement, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
FAQs for Hill Green
Do you cover Hill Green for sand mastic?
Yes. Our work covers London and the South East, and Hill Green is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Newport (Essex) station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can I choose the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What affects the quote in Hill Green
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- Working hours on commercial sites
- The type of sealant required
- The size of the job
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
To make quoting easier, let us know:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- The rough size of the job
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Why act early in Hill Green
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Around Hill Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
