What else we do in Lunsford's Cross
Windows and doors in Lunsford's Cross
Lunsford's Cross is close to 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Ninfield Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What happens if it’s left?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Lunsford's Cross can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Common problems we fix in Lunsford's Cross
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they normally need raking out.
The problems people usually mention when they call include:
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
- Draughts and rain around sash boxes
- Old sand mastic that has cracked, crumbled or fallen out
Rented homes near Collington station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
Before booking anyone
- Is VAT in the price?
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Check with your local planning authority if your home is listed
- Get any rot dealt with first
- Make sure water runs off the sill
- Don’t paint over the new mastic
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
Your questions about sand mastic in Lunsford's Cross
Do you work for landlords with property near Collington station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Does living near the coast affect sand mastic in Lunsford's Cross?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll say how long yours will take.
Can you match the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before we start.
Are you fully insured?
Yes. We are fully insured.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long does sand mastic take to go off?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
