About our sand mastic in Watch House Green
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. We work on stone surrounds, tenement windows and period & listed homes, and the jobs we see most are window mastic to renew ahead of painting and draughty sash windows at the surround.
Homes in small places like Watch House 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 is not right with it, call 0345 464 0079 or email us.

Sand mastic in Watch House Green: local notes
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.
In the older streets around Church of the Holy Cross, the joint between an old wall and a newer frame is generally the first place rain gets in. For site and facilities teams at buildings such as Felsted Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Do you hold any approvals?

Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Where do you work from?
Mr Mastic is based in Crawley. We cover Watch House Green and the rest of Essex, along with the rest of our area.
Why it’s worth doing now in Watch House Green
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Around Watch House Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. 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.
How we quote for sand mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- The amount of work
- Mould in or behind the old joints
- When we can work, for business premises
- The old material and how stubborn it is
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- A few photos by email, if you can
- The problem you’ve noticed
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or email us.
How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere like Watch House Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
