About our sand mastic in Appleford-on-Thames
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you’re dealing with mastic worn away on windows facing the weather and mastic that needs renewing before redecorating, we can help.
Somewhere as small as Appleford-on-Thames, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Every job comes with our 12-month guarantee, wherever you are in Oxfordshire.

Windows and doors in Appleford-on-Thames
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. Historic houses like Clifton Hampden Manor (about 1.9 miles north-east) are a reminder that the area around Appleford-on-Thames has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Appleford station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Managing a site like Didcot Girls' School? Then its window and door frames need their mastic kept sound, just like a home’s.

- Mastic that needs renewing before redecorating

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Get any rot dealt with first
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Landlord and commercial work in Appleford-on-Thames
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Why act early in Appleford-on-Thames
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Appleford-on-Thames, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
