How we handle window mastic in Oakley Green
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. Typical jobs include mastic that has split away from the wall and leaking joints at the ends of sills, across aluminium frames, patio & French doors and timber windows & doors.
Homes in small places like Oakley Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Oakley Green, the journey is planned in advance: 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.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks

Advice
What the job involves on each surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
How we quote for window mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- When we can work, for business premises

Common problems we fix in Oakley Green
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Look out for these signs:
- White mastic on grey or black frames
- Damp patches on the reveal after heavy rain
- Cracked sealant at the sill ends
- Draughty joints inside around the window
If you live in an older home near All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Which colour the sealant will be
- How long to leave it before use
- The length of the guarantee
- Whether the sealant suits the joint
Can I do it myself?
A careful DIYer can reseal a simple joint, 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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Oakley Green homes and the weather
Historic houses like St Leonard's Hill (about 1 mile south-east) are a reminder that the area around Oakley Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Windsor & Eton Central station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Alexander First School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Do not use solvent cleaners on the joint
- Look round the frames every year or so
- Use gentle cleaners on frames and sealant
- Wipe condensation off the frames
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or email us.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
