Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Window mastic in Stubbings
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you have white mastic on grey or black frames and untidy mastic left by window fitters, we can put it right, on composite doors, uPVC windows and window sills alike.
Mastic can only go onto a dry, clean joint, so window work in Stubbings is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Window mastic in Stubbings: local notes
Historic houses like Harleyford Manor (about 2.2 miles north-west) are a reminder that the area around Stubbings 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Burchetts Green CofE Infants' School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Furze Platt station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What happens if it’s left?
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Older cottages and farmhouses around Stubbings can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Make sure the drainage slots aren’t blocked
- Paint up to the joint, not over it
- Ventilate rooms so frames do not stay wet inside
- Keep paint and stain on wooden frames in good order
Most silicone sealants will not take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
What we’re called out for in Stubbings
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
If you live in an older home near Church of St. James the Less, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- What insurance they hold
- What the cure time is
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Surface by surface
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job. Somewhere as small as Stubbings, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Clear items away from the joints we’re working on
