Sand mastic in Ratley, done properly
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. If you’re dealing with cracked mastic round a front door frame and draughts and rain around sash boxes, we can put it right, on brick reveals, tenement windows and period & listed homes alike.
Homes in small places like Ratley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by our 12-month guarantee, wherever you are in Oxfordshire.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. In a small place like Ratley, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

What happens if it’s left?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Ratley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What sand mastic looks like in Ratley
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Upton House (about 1.3 miles south-west) nearby, there’s older building stock in the area around Ratley as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In and around Ratley, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Stone surrounds

Do you need sand mastic in Ratley?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
These are the problems we are asked about most:
- Crumbling sand mastic round a window
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
Homes close to Church of St Peter Ad Vincula include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
