Common problems we fix in Langney
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Keep an eye out for these signs:
- Mastic round period door frames that has failed
- Crumbling sand mastic round a window
- Modern sealant on a period surround
- Failed mastic on an exposed elevation
If you look after a building such as Langney Primary Academy, its window and door frames need their mastic kept sound, just like a home’s.

About our sand mastic in Langney
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you’re dealing with weathered mastic on the most exposed windows and modern sealant on a period surround, we can put it right, on period & listed homes, timber door frames and brick reveals alike.
Many houses in smaller places like Langney have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
All our work comes with a 12-month guarantee, wherever you are in East Sussex.

Why deal with it now?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Homes in smaller places like Langney 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.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Your questions about sand mastic in Langney
Can you help a landlord with a rental near Pevensey & Westham station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Does living near the coast affect sand mastic in Langney?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you come to Langney?
Yes. We cover Langney. To book, call 0345 464 0079 or email us.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will talk you through it.
How long will you be here?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll tell you how long to expect.
How to look after the new joints
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Sort the mastic before the decorators arrive
- Keep sills and gutters clear so water drains away
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
Surface by surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Frames and glazing around Langney
Langney is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St. Richard, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Pevensey & Westham station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- When we can work, for business premises
- The number of rooms or windows
- The number and length of the joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Roughly how big the job is
- Where the property is
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or email us with the details, and pictures are welcome.
Honest limits
A few problems are outside what sealant work can do:
- Putty and glazing repairs
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal
- Tenement windows
- Brick reveals
- Timber door frames
- Period & listed homes
- Sash and case windows
- Stone surrounds
The process
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours for a single window, longer for several. In a smaller place like Langney, 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.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
