Sand mastic in Hampton Poyle
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. 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 silicone on a period window that looks wrong.
Around Hampton Poyle, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Every job is covered by a 12-month guarantee, wherever you are in Oxfordshire.

How the visit works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere as small as Hampton Poyle, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Advice
How we quote for sand mastic
Your quote is based on your job. We take into account:
- Any mould that needs treating
- The product the joint needs
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- The type of property
We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or email us and describe the job, and pictures are welcome.
What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Broken panes
- Crumbling stone or brickwork round the window
- Sashes that rattle, stick or will not open
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Period & listed homes
- Tenement windows
- Timber door frames
- Sash and case windows
- Brick reveals
- Stone surrounds
Do you need sand mastic in Hampton Poyle?
Timber frames move with the seasons. That movement opens up the mastic joint over time.
The problems people usually mention when they call include:
- Patchy fillers round a sash window
- Open joints round the window box
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
Rented homes near Islip station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before booking
- What guarantee comes with the work
- When the joint can take water or movement
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
How the job changes by surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
What sand mastic looks like in Hampton Poyle
Historic houses like Blenheim Palace (about 3.9 miles west) are a reminder that the area around Hampton Poyle has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, 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 Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Gosford Hill School? Then the mastic around its windows and doors needs looking after like any other building’s.

Why it’s worth doing now in Hampton Poyle
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. In a small place like Hampton Poyle, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

Questions from Hampton Poyle
Can you help a landlord with a rental near Islip station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Hampton Poyle?
Yes, Hampton Poyle is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Should I use sand mastic or silicone?
We’ll help you decide. Sand mastic suits many period homes and newer frames suit modern sealant.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Landlords and letting agents in Hampton Poyle can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
