About our sand mastic in Moreton
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. We work on period & listed homes, sash and case windows and tenement windows, and the jobs we see most are modern sealant on a period surround and old cement repairs round a window that have failed.
Outdoor sealant needs dry, clean surfaces, so work on frames around Moreton is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, it’s backed by our one-year guarantee in Moreton and across Essex.

Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
What affects the quote in Moreton
We quote each job individually. This is what makes a difference:
- The amount of work
- Access and height
- Whether there’s mould to deal with
- When we can work, for business premises
What you pay reflects the work, not guesswork. That is why we ask a few questions first.

What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Moreton, the journey is planned in advance: 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.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare

Moreton homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Signs you need sand mastic in Moreton
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
The most common problems we see are:
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
If you look after a building such as Moreton Church of England Voluntary Aided Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Sashes that need overhauling
- Damaged stone surrounds
- Decisions on consent for listed homes

Other services in Moreton
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
