About our window mastic in Oxley Green
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have old mastic that has gone black or come away and whistling draughts around closed windows, we can help, on window sills, patio & French doors and timber windows & doors alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Oxley Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Big or small, you get the same one-year guarantee.

What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house for a typical job. In a small place like Oxley Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit

What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. Around Oxley Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Windows and doors in Oxley Green
With historic houses such as Layer Marney Tower (about 2.3 miles north-east) nearby, there’s older building stock in the area around Oxley Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Kelvedon station, renewing tired window mastic between tenants heads off draught and damp complaints.

Landlords, agents and businesses in Oxley Green
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Surface by surface
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.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.
Common problems we fix in Oxley Green
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Old mastic that has gone black or come away
- Leaking joints at the ends of sills
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
Managing a site like Thurstable School? Then its window and door frames need their mastic kept sound, just like a home’s.
