Sand Mastic in Hinksey Hill
Window and door surrounds in Hinksey Hill need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
- Gaps round a timber door in stone or brick
Sand mastic in Hinksey Hill
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. If you are dealing with old sand mastic that has cracked, crumbled or fallen out and silicone on a period window that looks wrong, we can help, whatever the surface.
Somewhere as small as Hinksey Hill, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Honest limits
New sealant cannot fix everything, and we’ll tell you before any work starts. It won’t solve:
- Crumbling stone or brickwork round the window
- Sashes that rattle, stick or will not open
- Decayed frames that need repair

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Do not run silicone over sand mastic
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Hinksey Hill questions
Is Hinksey Hill within the area you cover?
Yes, Hinksey Hill is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do sand mastic in Hinksey Hill?
Yes. We work across London and the South East, and Hinksey Hill is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Can landlords and businesses book you?
Yes, often. We can quote for several properties at once.
What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
What guarantee comes with the work?
Our 12-month guarantee applies to all our work.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Surface by surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Frames and glazing around Hinksey Hill
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Holywell Manor (about 2.3 miles north) are a reminder that the area around Hinksey Hill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as New Hinksey Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Oxford station, any sash windows need sound mastic to keep draughts and rain out.

What affects the cost of sand mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- How much there is to do
- The number of rooms or windows
- Whether there’s mould to deal with
- The product the joint needs
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
To help us quote quickly, please include:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- The problem you’ve noticed
- The rough size of the job

Why it’s worth doing now in Hinksey Hill
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Hinksey Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

How it works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a single window, longer for several, including the tidy-up. In a small place like Hinksey Hill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
