Window mastic in Botolph Claydon, done properly
Around Botolph Claydon we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you are dealing with water coming in at the bottom corners of a door and draughts coming in around windows and doors, we can put it right, whatever the surface.
Homes in small places like Botolph Claydon often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Aftercare tips
To keep the joints looking good and working properly:
- Avoid harsh chemicals near the mastic
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

When to call us in Botolph Claydon
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
These are the problems we’re asked about most:
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
If you live in an older home near Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- Whether they’re fully insured
- What product goes in the joint
- Whether all the old sealant comes out first

Botolph Claydon homes and the weather
Historic houses like Claydon House (about 1 mile west) are a reminder that the area around Botolph Claydon has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as East Claydon Church of England School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Botolph Claydon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Advice
When something else is needed
In fairness, there are a few things sealant will not fix:

- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. 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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
