Pilley Sand Mastic
We cover Pilley for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Gaps round a timber door in stone or brick
- Gaps where the frame meets the masonry
- Tired mastic found when preparing windows for paint
Leave it or put it right?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Pilley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

How we handle sand mastic in Pilley
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. Typical jobs include open joints round the window box and old cement repairs round a window that have failed, across tenement windows, brick reveals and stone surrounds.
Homes in small places like Pilley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All our work is covered by our 12-month guarantee.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several. Somewhere like Pilley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling 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.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

What sand mastic looks like in Pilley
Pilley 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. Historic houses like Beaulieu Palace House (about 4.4 miles north-east) are a reminder that the area around Pilley has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Saint Nicholas Chapel include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Lymington Town station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Pilley is about 2 miles north of Lymington, in Hampshire. Jobs in Pilley get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 683 towns and villages across Hampshire, large and small. For nearby work, see our Southampton page (11 miles or so).
Work in SO41 works the same way as everywhere else we cover. If you need sand mastic at a property on Pilley Street, Burnt House Lane and May Lane or anywhere close by, we can help. Close by, we work in Pilley Bailey (1 mile north-east), Warborne (1 mile south-west), Bull Hill (1 mile east), Portmore (1 mile south-east) and Boldre (1 mile west).

Local landmarks in Pilley
Typical jobs here are in homes near Priestlands School, The Red Lion Inn and Southlands School. The closest station to Pilley is Lymington Town station, roughly 1.5 miles south. A little further out are St Barbe Museum and Art Gallery (1.7 miles south) and Lymington New Forest Hospital (1.1 miles south-west). For a walk, there’s Boldre Foreshore.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the cost of sand mastic
We do not publish a price list, because jobs vary so much. What we look at:
- How many areas need sealing
- How much there is to do
- Whether there’s mould to deal with
- Which sealant suits the joint

Common questions in Pilley
Is Pilley within the area you cover?
Yes. Pilley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Lymington Town station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Can you seal over the old sealant?
No, it won’t last. 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.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can I choose the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
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.
Do you need sand mastic in Pilley?
Shallow joints are a common cause. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
These are the problems we’re asked about most:
- Window mastic to renew ahead of painting
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
Managing a site like William Gilpin Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
