Sand mastic in Oakshott: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Liss station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Sand mastic in Oakshott
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have patchy fillers round a sash window and mastic worn away on windows facing the weather, we can put it right, whatever the surface.
In a village or hamlet like Oakshott, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Surface by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Oakshott, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

What affects the cost of sand mastic
The quote reflects the job in front of us. We look at:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- How many rooms, windows or areas are involved
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Cracked or broken glass

- Sashes that rattle, stick or will not open
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Oakshott questions
Can you do sand mastic in Oakshott?
Yes. Our work covers London and the South East, and Oakshott is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Liss station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
How long does sand mastic take to go off?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Do you have insurance?
Yes, we’re fully insured.
What guarantee comes with the work?
Our one-year guarantee covers every job.
How do I get a quote for sand mastic in Oakshott?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How to look after the new joints
To keep the joints looking good and working properly:
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
- Look over the window mastic once a year
- Avoid heavy scraping on the mastic joint
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
