Window mastic in Picket Twenty
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. We are often asked to deal with draughty joints inside around the window and gaps where the sill meets the wall, across timber windows & doors, patio & French doors and composite doors.
In a village or hamlet like Picket Twenty, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work is covered by our 12-month guarantee, wherever you are in Hampshire.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep timber frames painted
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Use gentle cleaners on frames and sealant
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. Catching it early keeps the fix to a reseal.

What else we do in Picket Twenty
Windows and doors in Picket Twenty
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Pilgrims' Cross CofE Aided Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near United Reformed Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Andover station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why act early in Picket Twenty
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Picket Twenty, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Why book with us

Honest limits
To be straight with you, there are a few things sealant won’t fix:
- A sash or casement that won’t close properly
- Damp problems in the wall away from the window
- 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’ll tell you honestly before you book.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Different surfaces, different methods
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a morning for a couple of windows and a door. Somewhere as small as Picket Twenty, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
