About our sand mastic in Kirby Cross
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for a silicone bead on a sash window that spoils the look and crumbling sand mastic round a window, on period & listed homes, stone surrounds and timber door frames.
In smaller places like Kirby Cross, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Our work is backed for twelve months, in Kirby Cross and everywhere else we cover.

Questions from Kirby Cross
Do you work for landlords with property near Frinton-On-Sea station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Does the coastal weather in Kirby Cross affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you come to Kirby Cross?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick generally suit sand mastic and newer frames usually get a flexible sealant.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic can sit properly.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Have rotten timber repaired before new mastic goes in
- Keep sills and gutters clear so water drains away
- Don’t run silicone over sand mastic
- Find out about consent before window work on a listed home
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows from start to finish. A visit to Kirby Cross 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.
- We remove the old, loose mastic.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area
- Clear items away from the joints we’re working on

Related advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Surface by surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
How we quote for sand mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- The number and length of the joints
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That is why we ask about the job first.
What to tell us for a quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- How we’d reach the joints
- The type of property
- The problem you’ve noticed
Getting a quote is simple: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Kirby Cross homes and the weather
Kirby Cross is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Frinton-On-Sea station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around St Mary Magdalene, the joint between an old wall and a newer frame is normally the first place rain gets in.

Common problems we fix in Kirby Cross
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Old cement repairs round a window that have failed
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
- Wind and rain getting in round a sash window
Managing a site like Frinton-on-Sea Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
