About our sand mastic in Pondwell
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Common call-outs are for a silicone bead on a sash window that spoils the look and old cement repairs round a window that have failed, on stone surrounds, period & listed homes and timber door frames.
Around Pondwell, 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.
Every job is covered by our 12-month guarantee, wherever you are in the Isle of Wight.

Your questions about sand mastic in Pondwell
Is sand mastic in a coastal place like Pondwell any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Smallbrook Junction station?
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 work begins.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Is the work guaranteed?
Our 12-month guarantee covers every job.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
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. The old sealant has to come out completely.
Why act early in Pondwell
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Around Pondwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How the visit works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for a single window, longer for several. In a small place like Pondwell, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Check with your local planning authority if your home is listed
- Clear gutters so water doesn’t pour onto the windows
- Inspect the joints round the windows every year or so
- Get any rot dealt with first
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What sand mastic looks like in Pondwell
Pondwell is within about 2 miles of 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. 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.
If you look after a building such as Nettlestone Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St. Peter's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Smallbrook Junction station, any sash windows need sound mastic to keep draughts and rain out.
