Window Mastic in Acton Vale
Mastic around window and door frames, sills and patio doors for homes and businesses in Acton Vale and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Untidy mastic left by window fitters
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. In a London area like Acton Vale, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Window mastic in Acton Vale, done properly
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on aluminium frames, uPVC windows and window sills, and people most often call us about cold air getting in at the frame edge and rushed sealant from a window installation.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking, and access in Acton Vale is something to talk through when you book.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Your questions about window mastic in Acton Vale
Is parking an issue for window mastic in Acton Vale?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near Acton Central station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Can you do the inside joint as well?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Are you insured?
Yes, we are fully insured.
Do you do commercial work?

When something else is needed
We will not take on work that won’t last, so these are the limits:

- A sash or casement that won’t close properly
- Condensation trapped between the panes

What the job involves on each surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Windows and doors in Acton Vale
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. 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.
For an older house near a landmark such as St Saviour's Centre for the Deaf, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Wendell Park Primary School, its window and door frames need their mastic kept sound, just like a home’s. As a London address, Acton Vale can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
