About our window mastic in Cliddesden
There are two joints on most windows. 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. Typical jobs include mastic that’s falling out in pieces and a bead that doesn’t match the frame, across patio & French doors, uPVC windows and window sills.
In a village or hamlet like Cliddesden, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same one-year guarantee.

Why deal with it now?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Around Cliddesden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What we’re called out for in Cliddesden
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame

What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Penetrating damp from a failed cavity tray or render
- Faulty window hardware
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before booking.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Cliddesden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Advice
Window mastic in Cliddesden: local notes
With historic houses such as The Vyne (about 4.8 miles north) nearby, there’s older building stock in the area around Cliddesden as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Leonard include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Cliddesden Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Yes, Cliddesden is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Cliddesden?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Is the new sealant paintable?
Not normally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Are you fully insured?
Yes. We’re fully insured for domestic and commercial work.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Avoid blasting the frames with a pressure washer
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
- Keep timber frames painted
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
