Why act early in Goring
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Homes in smaller places like Goring can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

How we handle sand mastic in Goring
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. Common call-outs are for weathered mastic on the most exposed windows and draughty sash windows at the surround, on period & listed homes, sash and case windows and stone surrounds.
Many houses in smaller places like Goring have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
All of our work is guaranteed for twelve months, in Goring and everywhere else we cover.

Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Any of these means the joints need attention:

Questions from Goring
Will you come out to Goring?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do sand mastic in Goring?
Yes, Goring is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We will give you a better idea when we quote.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames usually get a flexible sealant.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Renew mastic before redecorating the windows
- Get any rot dealt with first
- Don’t paint over the new mastic
- Find out about consent before window work on a listed home
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a single window, longer for several. For a job in Goring, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- On commercial sites, let us know about site rules

For landlords and businesses
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Surface by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Sand mastic in Goring: local notes
With historic houses such as Basildon Park (about 1.8 miles south) nearby, there’s older building stock in the area around Goring as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Thomas of Canterbury, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Goring Church of England Aided Primary School, the mastic around its windows and doors needs looking after like any other building’s.
