Sand mastic in Chipping Norton
Across Chipping Norton, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on tenement windows, sash and case windows and timber door frames, and people most often call us about crumbling sand mastic round a window and silicone on a period window that looks wrong.
Around Chipping Norton, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Frames and glazing around Chipping Norton
Rainfall in the South East is lower than in much 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 Chastleton House (about 4.2 miles west) nearby, there’s older building stock in the area around Chipping Norton 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.
If you let a flat or house near Kingham station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Chipping Norton School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in.

Common questions in Chipping Norton
I let a flat near Kingham station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Chipping Norton?
Yes, Chipping Norton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Leave it or put it right?
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Around Chipping Norton, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Different surfaces, different methods
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
How to look after the new joints
To keep the joints looking good and working properly:
- Find out about consent before window work on a listed home
- Do not paint over the new mastic
- Get any rot dealt with first
- Check the mastic when you check the paintwork
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Honest limits
A few problems are outside what sealant work can do:
- Decayed frames that need repair
- Broken panes
- Sashes that rattle, stick or will not open
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

What else we do in Chipping Norton
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints from start to finish. For a job in Chipping Norton, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
