About our window mastic in Weston Otmoor
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on patio & French doors, aluminium frames and timber windows & doors, and the jobs we see most are rushed sealant from a window installation and cold air getting in at the frame edge.
Somewhere as small as Weston Otmoor, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

When to call us in Weston Otmoor
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Any of these means the joints need attention:
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
If you live in an older home near Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- How the colour is chosen

What else we do in Weston Otmoor
The process
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Weston Otmoor needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Advice
When it is not the sealant
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- A sash or casement that will not close properly
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
Where we work in Weston Otmoor
- Aluminium frames
- Timber windows & doors
- Composite doors
- Window sills
- Patio & French doors
- uPVC windows
Looking after it afterwards
Looking after new joints is easy:
- Do not use solvent cleaners on the joint
- Paint up to the joint, not over it
- Wipe condensation off the frames
- Keep jet washers away from the mastic
Most silicone sealants won’t take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Questions from Weston Otmoor
Do you work for landlords with property near Islip 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.
Do you cover Weston Otmoor for window mastic?
Yes. We work across London and the South East, and Weston Otmoor is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
