What we’re called out for in Bighton
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.
These are the problems we are asked about most:
- Hard, cracked sealant around windows
- White mastic on grey or black frames
- Water coming in at the bottom corners of a door
- Leaking joints at the ends of sills
If you live in an older home near Church of All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in.

Window mastic in Bighton
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on timber windows & doors, composite doors and uPVC windows, and the jobs we see most are untidy mastic left by window fitters and cracked sealant at the sill ends.
Mastic can only go onto a dry, clean joint, so window work in Bighton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Bighton as everywhere else we work.

How it works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours for a few frames, or a day or more for a whole house. In a small place like Bighton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What else we do in Bighton
Different surfaces, different methods
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.

What window mastic looks like in Bighton
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hinton Ampner House (about 4.3 miles south) are a reminder that the area around Bighton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Perins School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Use gentle cleaners on frames and sealant
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Keep jet washers away from the mastic
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
