Sand mastic in Shellingford: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Faith include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our sand mastic in Shellingford
We work across Shellingford renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on brick reveals, tenement windows and period & listed homes, and common reasons people get in touch are patchy fillers round a sash window and cracked mastic round a front door frame.
Somewhere as small as Shellingford, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Ask us before painting near the mastic
- Keep modern sealant off the mastic
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
How the visit works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints in most cases. Somewhere as small as Shellingford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Tell us about any water getting in
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Related advice
What the job involves on each surface
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is usually favoured.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a small place like Shellingford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Do you need sand mastic in Shellingford?
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
The problems people usually mention when they call include:
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Gaps where the frame meets the masonry
- Cement or filler used on old window joints that has cracked
Schools such as Shellingford Church of England (Voluntary Aided) School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Questions from Shellingford
Can you do sand mastic in Shellingford?
Yes. Our work covers London and the South East, and Shellingford is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Shellingford?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long does the job take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before we start.
