Sand mastic for sash & case windows in Pangbourne, Oxfordshire
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homes and businesses in Pangbourne and across Oxfordshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Modern sealant on a period surround
- Tired mastic found when preparing windows for paint
- Draughty sash windows at the surround
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Have rotten timber repaired before new mastic goes in
- Clear gutters so water doesn’t pour onto the windows
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
About our sand mastic in Pangbourne
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. If you have mastic round period door frames that has failed and draughts and rain around sash boxes, we can help, whatever the surface.
Houses in smaller places like Pangbourne can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
All our work comes with a one-year guarantee.

Windows and doors in Pangbourne
With historic houses such as Basildon Park (about 1.9 miles north-west) nearby, there’s older building stock in the area around Pangbourne as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St James the Less, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Pangbourne station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Different surfaces, different methods
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Why act early in Pangbourne
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Around Pangbourne, 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.
Combining jobs into one visit generally makes better use of the time than several visits. We will give you a clear price for the lot.

What we do, step by step
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several. For a job in Pangbourne, 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 start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Mention any tricky access
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
