Questions from Nettlestead
Do you work for landlords with property near Wateringbury station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Can you do sand mastic in Nettlestead?
Yes, Nettlestead is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
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 tell you what we are using.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Signs you need sand mastic in Nettlestead
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
The problems people generally mention when they call are:
- Cracked mastic round a front door frame
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Mastic dropping out of the joint
In the older streets around St Mary's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
What your quote should include
- The length of the guarantee
- Who does the work, and how experienced they are
- What product goes in the joint
- When the joint can take water or movement
Sand mastic in Nettlestead: 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 Old Soar Manor (about 4.3 miles west) nearby, there’s older building stock in the area around Nettlestead 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 Wateringbury Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Wateringbury station, any sash windows need sound mastic to keep draughts and rain out.

Somewhere as small as Nettlestead, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.

Advice
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Avoid patching sand mastic with silicone
- Find out about consent before window work on a listed home
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
