Sand mastic in North Hayling
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. We work on brick reveals, sash and case windows and tenement windows, and common reasons people get in touch are wind and rain getting in round a sash window and window mastic to renew ahead of painting.
Around North Hayling, 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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep sills and gutters clear so water drains away
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Sashes that need overhauling

- Damaged stone surrounds

Do you need sand mastic in North Hayling?
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Signs it’s time to call us include:
- Gaps round a timber door in stone or brick
- Crumbling sand mastic round a window
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Leave it or put it right?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. In a small place like North Hayling, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Why book with us
- 20+ years of sealant experience
- Anti-fungal silicone where joints get wet

FAQs for North Hayling
Does the coastal weather in North Hayling affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to North Hayling?
Yes. North Hayling is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

What sand mastic looks like in North Hayling
North Hayling 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. With historic houses such as Warblington Castle (about 1.5 miles north) nearby, there’s older building stock in the area around North Hayling as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as The Hayling College are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Warblington station, any sash windows need sound mastic to keep draughts and rain out.
