How we handle sand mastic in Hazeley
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. If you are dealing with silicone on a period window that looks wrong and gaps round a timber door in stone or brick, we can put it right, whatever the surface.
Around Hazeley, 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.
All of our work is guaranteed for twelve months.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Surface by surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Hazeley homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Stratfield Saye House (about 3.1 miles north-west) nearby, there’s older building stock in the area around Hazeley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Mattingley Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Hazeley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

- Old cement repairs round a window that have failed
- Open joints round the window box
- Crumbling sand mastic round a window
- Cracked mastic round a front door frame
If you let a flat or house near Winchfield station, any sash windows need sound mastic to keep draughts and rain out.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep sills and gutters clear so water drains away
- Leave the new mastic unpainted
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
Avoid painting over the new mastic, as traditional guidance advises. If you’re redecorating, ask us first.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
