Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Ventilate rooms so frames don’t stay wet inside
- Keep timber frames painted
- Don’t paint over the silicone
- Wash the frames with mild soapy water
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Frames and glazing around Paddington Green
Historic houses like Winfield House (about 0.9 miles north-east) are a reminder that the area around Paddington Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
If you look after a building such as Ark Paddington Green Primary Academy, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St Mary on Paddington Green Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, 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.
If you do try it yourself, take your time over the 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.

How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. For a job in Paddington Green, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

When to call us in Paddington Green
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.
Look out for any of the following:
- Draughty joints inside around the window
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
Paddington Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
