How we handle sand mastic in West Hagbourne
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include open joints round the window box and gaps round a timber door in stone or brick, on timber door frames, period & listed homes and sash and case windows.
In a village or hamlet like West Hagbourne, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in West Hagbourne and everywhere else we cover.

Questions from West Hagbourne
Do you work for landlords with property near Didcot Parkway station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to West Hagbourne?
Yes, West Hagbourne is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Should I use sand mastic or silicone?
We’ll help you decide. Sand mastic suits many period homes and newer frames suit modern sealant.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
Leave it or put it right?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like West Hagbourne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Advice
What sand mastic looks like in West Hagbourne
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Brightwell Manor (about 4.5 miles north-east) are a reminder that the area around West Hagbourne has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Hagbourne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Didcot Parkway station, any sash windows need sound mastic to keep draughts and rain out.

How we quote for sand mastic
Call for a quick quote. What matters most is:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- The size of the job
- Whether the work is at height
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- If someone has resealed it before
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Surface by surface
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we’ll confirm what’s needed.
How to look after the new joints
To keep the joints looking good and working properly:
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
- Ask the planning authority about consent for listed or conservation-area homes
- Clear gutters so water doesn’t pour onto the windows
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Whether work needs listed building consent
- Decayed frames that need repair
- Damaged stone surrounds
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.
