Window mastic in Upper Farringdon, done properly
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have a bead that doesn’t match the frame and cold air getting in at the frame edge, we can help, on aluminium frames, patio & French doors and composite doors alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Upper Farringdon is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

DIY versus a professional finish
If you are 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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How we quote for window mastic
Jobs vary more than people expect. The main factors:

What we need to know
When you call or email, these details help:
- Where the job is, and your postcode
- The problem you’ve noticed

For landlords and businesses

Surface by surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
When to call us in Upper Farringdon
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Common reasons people contact us include:
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
- Draughty joints inside around the window
If you live in an older home near Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Upper Farringdon, 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.
- Frame and wall are cleaned and must be dry before sealing, 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.
How to prepare
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Mention any parking rules near the property

Frames and glazing around Upper Farringdon
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Bentworth Hall (about 3.9 miles north-west) are a reminder that the area around Upper Farringdon 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’s traditional sand mastic.
