How we handle sand mastic in Rush Green
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. Common call-outs are for gaps where the frame meets the masonry and draughty sash windows at the surround, on timber door frames, sash and case windows and brick reveals.
Houses in smaller places like Rush Green can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
Whatever the size of the job, you get the same 12-month guarantee.

Period and listed homes
Period homes look their best with traditional materials.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Windows and doors in Rush Green
Rush Green is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Thorpe Hall (about 4.4 miles north) are a reminder that the area around Rush 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’s traditional sand mastic.
If you live in an older home near Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Ravens Academy, the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
So the new joints stay in good condition:
- Sort the mastic before the decorators arrive
- Find out about consent before window work on a listed home
- Ask a joiner to look at soft timber first
- Don’t paint over the new mastic
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Do you need sand mastic in Rush Green?
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Tired mastic found when preparing windows for paint
- Open joints round the window box
- Draughts and rain around sash boxes
- Cement or filler used on old window joints that has cracked
For landlords with property near Clacton-On-Sea station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before you book

- Whether VAT is included
- How the colour is chosen
- Whether they seal over old material or remove it
How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to a full day, depending on how many windows. In a smaller place like Rush Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Mention any tricky access

Your questions about sand mastic in Rush Green
Does living near the coast affect sand mastic in Rush Green?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Is Rush Green within the area you cover?
Yes. Rush Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
What should I tell you?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
What happens if it’s left?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Homes in smaller places like Rush Green can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
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. The price is agreed before we begin.
