Sand mastic in Bradwell, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you’re dealing with gaps between timber frames and stone or brick and failed mastic on an exposed elevation, we can put it right, whatever the surface.
Homes in small places like Bradwell often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

What affects the quote in Bradwell
The price is agreed before any work begins. It’s based on:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- The type of sealant required
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Bradwell: your questions answered
Will you come out to Bradwell?
Yes. Bradwell is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is sand mastic in Bradwell guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
How long does the job take?
A typical job takes anything from a few hours to a full day, depending on how many windows, including the preparation. Your quote will say how long we expect yours to take.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will talk you through it.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
Can landlords and businesses book you?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Oxfordshire.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Why it’s worth doing now in Bradwell
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 Bradwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What you get with us
- A 12-month guarantee on all work

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. In a small place like Bradwell, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Clear the area around the work
- On commercial sites, let us know about site rules
- Mention any parking rules near the property

Advice
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Damaged stone surrounds
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Stone surrounds

- Sash and case windows
How to look after the new joints
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Don’t paint over the new mastic
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Bradwell homes and the weather
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.
For site and facilities teams at buildings such as Burford School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Mary include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
