Sand mastic in Shiplake
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. If you have gaps between timber frames and stone or brick and patchy fillers round a sash window, we can help, on brick reveals, stone surrounds and sash and case windows alike.
Around Shiplake, 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.
Whatever the size of the job, you get the same one-year guarantee in Shiplake and across Oxfordshire.

Shiplake: your questions answered
Is Shiplake in your area for sand mastic?
Yes, Shiplake is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Shiplake?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What sealant 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 worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Cracked or broken glass
- Sashes that need overhauling
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Where we work in Shiplake
- Tenement windows
- Sash and case windows
- Brick reveals
- Stone surrounds
- Period & listed homes
- Timber door frames
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Ask us before painting near the mastic
- Don’t run silicone over sand mastic
- Make sure water runs off the sill
- Inspect the joints round the windows every year or so
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
What happens on the day
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before we start. Most jobs take anything from a few hours to a full day, depending on how many windows. In a small place like Shiplake, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Mention any tricky access

Frames and glazing around Shiplake
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Greys Court (about 4.1 miles north-west) nearby, there’s older building stock in the area around Shiplake 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.
Managing a site like Shiplake Church of England School? Then its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Wargrave station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why it’s worth doing now in Shiplake
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Shiplake can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
