Sand Mastic in Fritwell
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homes and businesses in Fritwell and across Oxfordshire. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Modern sealant on a period surround
- Draughty sash windows at the surround
- Tired mastic found when preparing windows for paint
How to look after the new joints
After the cure time, these simple habits help:
- Keep sills and gutters clear so water drains away
- Look over the window mastic once a year
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Sand mastic in Fritwell
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on brick reveals, stone surrounds and tenement windows, and common reasons people get in touch are mastic worn away on windows facing the weather and wind and rain getting in round a sash window.
Mastic can only go onto a dry, clean joint, so window work in Fritwell is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Crumbling stone or brickwork round the window
- Sash cords, weights and draught-proofing of the sashes
- Decayed frames that need repair

The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. In a small place like Fritwell, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Mention any tricky access
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work

Why it’s worth doing now in Fritwell
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Fritwell, 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: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why choose Mr Mastic in Fritwell
- 12-month guarantee on every job

Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
What sand mastic looks like in Fritwell
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Olave include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Heyford station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Fritwell Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Landlord and commercial work in Fritwell
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
