Nyewood Sand Mastic

- Weathered mastic on the most exposed windows

- Gaps round a timber door in stone or brick
Sand mastic in Nyewood, done properly
Silicone on a period window often looks wrong and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on timber door frames, tenement windows and period & listed homes, and common reasons people get in touch are mastic dropping out of the joint and gaps between timber frames and stone or brick.
Homes in small places like Nyewood often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes as standard, so you’re covered after we have gone.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Is sand mastic better than silicone for my windows?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Can you replace silicone on a period window with sand mastic?
Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Signs you need sand mastic in Nyewood
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they normally need raking out.
The most common problems we see are:
- Gaps where the frame meets the masonry
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
If you let a flat or house near Petersfield station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Nyewood homes and the weather
With historic houses such as Uppark (about 2.7 miles south-west) nearby, there’s older building stock in the area around Nyewood as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Uppark, about 2.7 miles south-west, is one of the historic houses in the wider area around Nyewood, and older homes nearby need a sealant that suits their walls.

How to look after the new joints
So the new joints stay in good condition:
- Get any rot dealt with first
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Why it’s worth doing now in Nyewood
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Around Nyewood, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
