How we handle sand mastic in Frilford
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. If you have tired mastic found when preparing windows for paint and failed mastic on an exposed elevation, we can put it right, whatever the surface.
Around Frilford, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Why act early in Frilford
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Older cottages and farmhouses around Frilford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What sand mastic looks like in Frilford
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. Historic houses like Appleton Manor (about 2.6 miles north) are a reminder that the area around Frilford 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.
Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the job changes by surface
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Should I try it myself first?
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
So the new joints stay in good condition:
- Renew mastic before redecorating the windows
- Keep sills and gutters clear so water drains away
- Avoid heavy scraping on the mastic joint
- Keep modern sealant off the mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

Advice
Do you need sand mastic in Frilford?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where the frame meets the masonry
- Weathered mastic on the most exposed windows
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
Managing a site like Abingdon Preparatory School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- Is the old sealant removed completely?
- What happens if they find a problem under the old sealant
- Who turns up on the day
