Window & door mastic in East Claydon, Buckinghamshire
We cover East Claydon for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Black, perished sealant on frames
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
Do you need window mastic in East Claydon?
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Any of these means the joints need attention:
- Rushed sealant from a window installation
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- Black, perished sealant on frames
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Is the old sealant removed completely?
- Who turns up on the day
- What preparation is included
- Are they insured?
Window mastic in East Claydon, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We’re often asked to deal with cold air getting in at the frame edge and leaking joints at the ends of sills, on window sills, timber windows & doors and composite doors.
Somewhere as small as East Claydon, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work comes with our one-year guarantee, wherever you are in Buckinghamshire.

What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
FAQs for East Claydon
Do you cover East Claydon for window mastic?
Yes. Our work covers London and the South East, and East Claydon is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Will you come out to East Claydon?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Window mastic in East Claydon: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Claydon House (about 1.2 miles west) are a reminder that the area around East Claydon has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as East Claydon Church of England School, the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Make sure the drainage slots aren’t blocked
- Avoid blasting the frames with a pressure washer
- Do not use solvent cleaners on the joint
- Ventilate rooms so frames don’t stay wet inside
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. In a small place like East Claydon, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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.
Preparing for the visit
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
