Sand mastic in Nuptown: local notes
With historic houses such as St Leonard's Hill (about 3.5 miles east) nearby, there’s older building stock in the area around Nuptown as well as newer homes. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Michael and All Angels, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle sand mastic in Nuptown
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. If you are dealing with silicone on a period window that looks wrong and mastic worn away on windows facing the weather, we can put it right.
In a village or hamlet like Nuptown, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Nuptown, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes anything from a few hours to a full day, depending on how many windows. In a small place like Nuptown, access is generally 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.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Do you need sand mastic in Nuptown?

- Draughty sash windows at the surround
- Window mastic to renew ahead of painting
- Silicone on a period window that looks wrong
- Failed mastic on an exposed elevation
For landlords with property near Bracknell station, older sash windows in a rental need their mastic kept sound to keep the weather out.
