How we handle sand mastic in Shripney
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We are often asked to deal with mastic worn away on windows facing the weather and modern sealant on a period surround, on brick reveals, stone surrounds and tenement windows.
Around Shripney, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Common problems we fix in Shripney
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 most common problems we see are:
- Gaps where the frame meets the masonry
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
If you let a flat or house near Bognor Regis station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Make sure water runs off the sill
- Take care around the mastic when scraping paint
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
How it works
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several. In a small place like Shripney, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Preparing for the visit
- Move anything stored near the joints
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

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 mastic stays put. Older cottages and farmhouses around Shripney can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.

Shripney homes and the weather
Shripney is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of 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 Holy Cross Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Bersted Green Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Shripney
I let a flat near Bognor Regis station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Shripney?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
How long does sand mastic take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer, and we will tell you how long to expect.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is the work guaranteed?
Our one-year guarantee covers every job.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
