Sand mastic in South Hinksey, done properly
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, brick reveals and tenement windows, and the jobs we see most are silicone on a period window that looks wrong and window mastic to renew ahead of painting.
Somewhere as small as South Hinksey, 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.
All our work comes with a 12-month guarantee.

South Hinksey: your questions answered
Is South Hinksey in your area for sand mastic?
Yes, South Hinksey is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is South Hinksey within the area you cover?
Yes, we do. 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.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How long does sand mastic take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What sand mastic looks like in South Hinksey
Historic houses like Holywell Manor (about 1.8 miles north) are a reminder that the area around South Hinksey has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Managing a site like New Hinksey Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Lawrence, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What the job involves on each surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. In a small place like South Hinksey, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

What affects the quote in South Hinksey
There’s no set price list, because no two jobs are the same. What we look at:
- When we can work, for business premises
- How many areas need sealing
- Any mould that needs treating

Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive

- Let us know about stairs, lifts or work at height
