What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- Whether there’s mould to deal with
- When we can work, for business premises
- The old material and how stubborn it is
- The number of rooms or windows
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
What to tell us for a quote
When you contact us, these details help:
- Any access issues, like height or stairs
- Where the property is
- The rough size of the job
- Whether it has been sealed before
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or drop us an email with the details.
About our window mastic in Bradwell
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We’re often asked to deal with hard, cracked sealant around windows and a bead that doesn’t match the frame, on aluminium frames, window sills and patio & French doors.
In a village or hamlet like Bradwell, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our 12-month guarantee in Bradwell and across Oxfordshire.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Wash the frames with mild soapy water
- Keep paint off silicone joints
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Bradwell questions
Is there a guarantee on window mastic in Bradwell?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Can you do window mastic in Bradwell?
Yes, Bradwell is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
How much does window mastic cost in Bradwell?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Is the new sealant paintable?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.
Should I try it myself 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 doesn’t work out, we can still put it right.
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, then guaranteed for a year.
Different surfaces, different methods
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Window mastic in Bradwell: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Burford School, the mastic around its windows and doors needs looking after like any other building’s.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a few frames, or a day or more for a whole house. Somewhere like Bradwell needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Move anything stored near the joints

Why act early in Bradwell
Resealing frames is a short job: it takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like Bradwell, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
