Sand mastic in Telscombe
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you’re dealing with mastic round period door frames that has failed and cement or filler used on old window joints that has cracked, we can help, whatever the surface.
Houses in smaller places like Telscombe can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
Our work is backed for twelve months, in Telscombe and everywhere else we cover.

Landlords, agents and businesses in Telscombe
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. A visit to Telscombe is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on

Do you need sand mastic in Telscombe?
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.
The problems people generally mention when they call are:
- Weathered mastic on the most exposed windows
- Old sand mastic that has cracked, crumbled or fallen out
- Cement or filler used on old window joints that has cracked
- Window mastic to renew ahead of painting
Letting a property close to Southease station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before booking
- Whether VAT is included
- Whether all the old sealant comes out first
- How hidden problems are handled
- What the cure time is
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic in Telscombe: local notes
Telscombe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Monk's House (about 2.7 miles north-east) are a reminder that the area around Telscombe has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around The Parish Church of St Lawrence, 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 Telscombe Cliffs Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Questions from Telscombe
Is sand mastic in a coastal place like Telscombe any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
I let a flat near Southease station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
What information do you need?
Tell us what needs doing and where. If we need more, we will ask.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
How long does sand mastic take to go off?
Not right away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- Planning or listed building consent (your local planning authority decides)
- Sashes that need overhauling
- Decayed frames that need repair
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
Where we work in Telscombe
- Tenement windows
- Stone surrounds
- Timber door frames
- Brick reveals
- Sash and case windows
- Period & listed homes
Why deal with it now?
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Around Telscombe, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
