Window & door mastic in Holloway, Greater London
Mastic around window and door frames, sills and patio doors in Holloway, with a one-year guarantee on every job. Ask us for a quote.
- Damp patches on the reveal after heavy rain
- Hard, cracked sealant around windows
- Draughty joints inside around the window
Looking after it afterwards
Looking after new joints is easy:
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Repaint timber before it’s bare
- Keep jet washers away from the mastic
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Window mastic in Holloway
Around Holloway we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have damp patches on the reveal after heavy rain and whistling draughts around closed windows, we can put it right, whatever the surface.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Frames and glazing around Holloway
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. With historic houses such as Witanhurst (about 1.7 miles north-west) nearby, there’s older building stock in the area around Holloway as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Drayton Park station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Grafton Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a few frames, or a day or more for a whole house. In a London area like Holloway, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Signs you need window mastic in Holloway
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
These are the problems we’re asked about most:
- A bead that does not match the frame
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
- Whistling draughts around closed windows
As a London address, Holloway can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
