Sand mastic for homes and businesses in Shotover Hill
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with wind and rain getting in round a sash window and old sand mastic that has cracked, crumbled or fallen out, across sash and case windows, stone surrounds and tenement windows.
Homes around Shotover Hill range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
You get a one-year guarantee, the same in Shotover Hill as everywhere else we work.

Shotover Hill: your questions answered
Do you cover Shotover Hill for sand mastic?
Yes. Our work covers London and the South East, and Shotover Hill is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Do you cover smaller places like Shotover Hill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where is Mr Mastic based?
We work from Crawley. We cover Shotover Hill and the rest of Oxfordshire, along with the rest of our area.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
- Don’t paint over the new mastic
- Check with your local planning authority if your home is listed
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
Different surfaces, different methods
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Stone surrounds
The stone is treated with care while raking out the old mastic.
Quotes for sand mastic in Shotover Hill
Jobs vary more than people expect. The main factors:
- The size of the job
- Mould in or behind the old joints
- The product the joint needs
- How easy the joints are to reach
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Photos by email, if that is easy
We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or email us with the details, and pictures are welcome.
What happens if it’s left?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a smaller place like Shotover Hill, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.

What sand mastic looks like in Shotover Hill
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Holywell Manor (about 2.4 miles west) nearby, there’s older building stock in the area around Shotover Hill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Holy Trinity Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Wood Farm Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Oxford station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a single window, longer for several. In a smaller place like Shotover Hill, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive

For landlords 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.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

- Broken panes
- Rotten sashes, sills or window boxes (a joiner’s job)
- Planning or listed building consent (your local planning authority decides)
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
