Questions from Shilton
Can you do window mastic in Shilton?
Yes, Shilton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Will you come out to Shilton?
Yes. Shilton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
Can you do upstairs windows?
Yes, in most cases. Access is planned before any work starts.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
Window mastic in Shilton, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with a bead that doesn’t match the frame and leaking joints at the ends of sills, we can help, whatever the surface.
Homes in small places like Shilton 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.
Our work is backed for twelve months.

What else we do in Shilton
Common problems we fix in Shilton
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
These are the problems we’re asked about most:
- A bead that does not match the frame
- Hard, cracked sealant around windows
- Mastic that is falling out in pieces
- Cracked sealant at the sill ends
Schools such as Carterton Community College are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What affects the cost of window mastic
The quote reflects the job in front of us. We take into account:
- Whether old sealant or filler has to be cut out
- The size of the job
- The product the joint needs
- Working hours on commercial sites
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What to tell us for a quote
To make quoting easier, let us know:
- If someone has resealed it before
- What’s wrong with the joints now
- Photos by email, if that is easy
- Any access issues, like height or stairs
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details.
Shilton homes and the weather
Historic houses like Minster Lovell Hall (about 4 miles north-east) are a reminder that the area around Shilton 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. 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.
Homes close to Church of the Holy Rood include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Shilton is about 1 mile north-west of Carterton, in Oxfordshire. Jobs in Shilton get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Shilton is one of 443 towns and villages in Oxfordshire we cover. We also work in Oxford, about 16 miles from Shilton.

What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
- Faulty window hardware
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Composite doors
- uPVC windows
- Aluminium frames
- Timber windows & doors
- Patio & French doors
- Window sills
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a morning for a couple of windows and a door from start to finish. Somewhere as small as Shilton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Why act early in Shilton
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Shilton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
