How we handle sand mastic in Townhill Park
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you’re dealing with gaps where the frame meets the masonry and mastic worn away on windows facing the weather, we can help, whatever the surface.
In a smaller place like Townhill Park, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
A one-year guarantee comes as standard.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Renew mastic before redecorating the windows
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
- Get any rot dealt with first
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
How the visit works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. In a smaller place like Townhill Park, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Advice
Sand mastic in Townhill Park: 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 South Stoneham House (about 0.9 miles north-west) nearby, there’s older building stock in the area around Townhill Park as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Townhill Junior School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Swaythling station, older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to St. Mary's Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Different surfaces, different methods
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.

What do you need from me for a quote?

What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.

A typical job takes a few hours for a single window, longer for several. We will confirm how long when we quote.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
