Sand mastic for homes and businesses in Braishfield
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Common call-outs are for patchy fillers round a sash window and draughts and rain around sash boxes, across brick reveals, timber door frames and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Braishfield is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a single window, longer for several. For a village or hamlet like Braishfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the surrounds with you and agree the joints to renew.
- 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.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

Advice
Looking after it afterwards
After the cure time, these simple habits help:
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
- Sort the mastic before the decorators arrive
- Don’t paint over the new mastic
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Your questions about sand mastic in Braishfield
Do you cover smaller places like Braishfield?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Romsey station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
When will the new mastic be hard?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can you replace silicone on a period window with sand mastic?
Yes. We remove the silicone and clean the joint, then point it with sand mastic.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
Sand mastic in Braishfield: local notes
The South East is one of 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 Mottisfont Abbey (about 3.3 miles north-west) nearby, there’s older building stock in the area around Braishfield as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Braishfield Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What else we do in Braishfield
Why it’s worth doing now in Braishfield
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Around Braishfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

Look out for these signs:
- Draughty sash windows at the surround
- Mastic dropping out of the joint
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
If you let a flat or house near Romsey station, any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
