Sand Mastic in Lyford
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for Lyford, backed by a one-year guarantee. Call for a quick quote.
- Modern sealant on a period surround
- Gaps between timber frames and stone or brick
- Draughty sash windows at the surround
What happens if it’s left?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Lyford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

How we handle sand mastic in Lyford
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include gaps where the frame meets the masonry and failed mastic on an exposed elevation, across brick reveals, timber door frames and sash and case windows.
Somewhere as small as Lyford, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Big or small, it’s backed by our 12-month guarantee in Lyford and across Oxfordshire.

How it works
At the end, we look at the finished work together. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. In a small place like Lyford, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Don’t paint over the new mastic
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
- Inspect the joints round the windows every year or so
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Sand mastic in Lyford: local notes
With historic houses such as Longworth House (about 3.2 miles north) nearby, there’s older building stock in the area around Lyford as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Lyford, as everywhere, sand mastic is only as good as the preparation behind it.

Do you need sand mastic in Lyford?
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint, and they usually need raking out.
Common reasons people contact us are:
- Cracked mastic round a front door frame
- Old cement repairs round a window that have failed
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.
Questions to ask before you book
- Which colour the sealant will be
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- When the joint can take water or movement

DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
