About our sand mastic in Little Wittenham
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on period & listed homes, tenement windows and brick reveals, and people most often call us about window mastic to renew ahead of painting and patchy fillers round a sash window.
Homes in small places like Little Wittenham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, you get the same one-year guarantee.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Little Wittenham homes and the weather
With historic houses such as Brightwell Manor (about 1.7 miles south-east) nearby, there’s older building stock in the area around Little Wittenham as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Long Wittenham (Church of England) Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
- Get any rot dealt with first
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Signs you need sand mastic in Little Wittenham
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
If you can see any of these, it’s time to have the joints looked at:
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
- Patchy fillers round a sash window
- Weathered mastic on the most exposed windows
Rented homes near Appleford station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Little Wittenham: your questions answered
Can you help a landlord with a rental near Appleford station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Little Wittenham?
Yes. Little Wittenham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
How long does the job take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. We will confirm how long when we quote.
